switches
Hi. I have two questions: 1. Does anyone know where on the web we can have some free access to switches so that we may telnet into them? FirewallKing.com has only router access as far as I could tell. 2. At work, We are running an IBM 2210 router, with two hubs (ethernet 10bt) and one HP switch. I wnat to install a cisco catalyst 1900 series switch as well. Need I run the crossover cable from switch to switch/hub? Is there any ohte rway I can implement it? Also, can I run stp on just the 1900 series? I dont know that much about HP switches, and am focusing on cisco at this time. THanks __ Do You Yahoo!? Yahoo!

Title: Switches !!! Installed a few 10/100 3com switches in our network, after a while started getting Ip conflict errors. The swithces were getting ip address from our obedient NT DHCP servers, unfortunately the switches are BOOTP enabled they got ips from some DHCP servers, ( I dont know from where as none of our DHCP servers had a reservation for those ips.). The DHCP started to lease the same address to some wins dhcp enabled clients, which was granted to the switch this resulted in the conflicts. Still trouble-shooting from where the Swiches took the ip addresses. Maybe some of you can put some light on it.

RE: switches
Charles, You are right, you would install the Catalyst 1900 by connecting it to the HP switch with a crossover cable. I don't know much about HP switches either but the 1900 runs STP by default. Here's a configuration link for the 1900.

Cascading Switches
I've looked through the archives as well as on CCO but could not find a definite answer to the limit of "cascading" switches, specifically catalyst 2900's. I saw the discussion earlier this year/last year that talked about the difference between "cascading" and "stacking". I'm not looking for shared management (stacking) but just how many switches can I cascade together to get the highest port concentration. Just a simple (or bad network design)of one switch to another to another to N... because I ran out of ports and do not want to by a real switch scenario How many can I connect? My first reaction to this question was that it had to be limited by the CAM of each switch but can't find an answer. Again it is for the 2900 series switch.

RE: Switches !!!
a1. How are MAC addresses used on a switch: The MAC address of the switch, depending on the interface being used, handle this in different ways. Some Catalyst switches assign a global MAC address, some switches use a pool of addresses assigning one to each interface(You can assign one manually), and sometimes the MAC address can be a virtual MAC address when using HSRP on mulitiple internal route processors such as the MSM, RSM, RSFC, NFFC, NFFCII or the MSFC. The switch is assigned an IP address and default gateway which allows you to telnet to the switch. On most switches you can also use the your webrowser to access the switches configuration and make changes simply by typing in the switches IP address. a2. If two nodes on the same switch want to communicate on the same switch: (This question requires a long answer!) If: A. They are connected to the same port on the switch the switch does nothing since the two nodes are in the same collision domain they will see each others traffic. If B. They are in the same VLAN and reside on the same switch, the switch learns the location of each node attached by reading the first frame received and logging the source address and port of arrival in it's Content Addressable Memory(CAM) table. When the switch receives another frame it checks the CAM table and if it knows the port the destination node resides on it forwards the frame directly to that port. If it does not know the port, it broadcasts the frame to every port which are members of the same VLAN with the exception to the port of arrival. If C. If the destination and source node reside on ports assigned to different VLANs on the switch, the switch requires an external router to resolve the address and send the packet back to the switch. If the switch contains an internal route processor, the external router needs to only resolve the first packet and then the internal route processor can finish the job from there. (An external router needs to be used so that a routing protocol can be used to map the network topology to base it's routes.) Hope this answers your questions.

RE: Switches !!!
Hey Sean. This is regarding the following passage taken from the your previous reply to this thread: If C. If the destination and source node reside on ports assigned to different VLANs on the switch, the switch requires an external router to resolve the address and send the packet back to the switch. <*** If the switch contains an internal route processor, the external router needs to only resolve the first packet and then the internal route processor can finish the job from there. ***> (An external router needs to be used so that a routing protocol can be used to map the network topology to base it's routes.) The second sentence implies that there will always need to be at least one router in any switched network. Is this actually correct? I seem to remember reading that there are fully switched networks utilizing layer three switching as the routing mechanism. What I am getting at is I thought Route Switch Processors are layer three devices and fully capable of making their own routing decisions, in which case there would be no need for a router.

What Sean implied here is you will always need a router to route between VLAN's. I thought you could use a router (router on a stick)OR a RSP.

RE: Switches !!!
Fred Switches even with an internal route processor cannot take the place of a router. The first packet in Multilayer switching is resolved by the external router. The internal route processor learns from the forwarding decision made by the external router and then uses that resolution for the remainder of the flow from the source to the destination without using the external route processor. Unless the external route router must be used as a gateway to leave the local boundaries. To answer your question, a switched network must still use an external router for Layer 3 resolution. Switches using Layer 3 modules merely releive the router of precious processing power. Hope this helps. I have two books on switching which can be used to answer your questions.

RE: Switches !!!
I've just been doing some research for a customer proposal. What I have found is that the Cisco's so-called layer three switches will natively route RIP, but if you want more capability you pay for a software enhancement that will permit OSPF, IGRP, and EIGRP, or in other words, turns the L3 switch into a real router :-> Is this more or less what you folks are talking about?

RE: Switches !!!
You will always need to have a router or a route processor to router between VLANS. At least with current technology. Layer 3 switching is really just being able to processes a route and then forward at switch or wire speeds. It still needs to process a route, and is routing between lan segments. In the second part I believe Sean is speaking about Netflow switching where the router determines how to route a source/destinatioon once, and once the switch learns how that packet was routed through the switch, the next time it recieves a similiar source/destination that normaly would require route processing it will just switch the packet to the appropriate port based on what it learned the last time without asking the router to process a route. -Original Message- From: Frank Wells [mailto:[EMAIL PROTECTED]] Sent: Friday, August 11, 2000 12:30 PM To: [EMAIL PROTECTED] Subject: RE: Switches !!!

RE: Switches !!!
Is it possible that Cisco's Layer 3 switching has evolved beyond the way things are done of the 5xxx platform. For example, my reading of the product description of the Catalyst 4908G-L3 switch provides this info: - The Catalyst 4908G-L3 provides a complete IP routing solution without sacrificing any of the services that are required to build a scalable network. The Catalyst 4908G-L3 is a feature-rich switch with full Cisco IOS implementation that allows network managers to continue to administer and manage their networks as they do today while scaling their backbone bandwidths to gigabit speeds. The Catalyst 4908G-L3 supports all the routing protocols that are used today in mid-sized networks. These protocols include: * Interior Gateway Routing Protocol (IGRP) * Enhanced IGRP (EIGRP) * Open Shortest Path First (OSPF) * Routing Information Protocol (RIP) Versions 1 and 2 * Static routes * Route redistribution Now if this guy is an OSPF router, and therefore contains a full table of the network topology, why does it have to consult an external router to forward a packet? Doesn't it have its own forwarding table? I remain unenlightened, and appreciate clarification.

RE: Switches !!!
I have to say that I'm a little confused my self! RSP "Route Switch Processor" is used by the 7500's RSM "Route Switch Module" can be used by Cat5500 for example. We have currently 7 5500's with RSM's, and I tell you it is doing all of the routing for us to include VLANs. Lot's of then. What I am trying to say here is that I can Route between VLAN's just fine with an RSM. I think that someone missed typed RSP with RSM.

RE: Switches !!!
Frank, I had the same problem as you did with the concept before. I believe that Sean and Chris are both talking about the same thing. RSM module is essentiality a router that is design to route between VLANs instead of networks. Remember, there are many kinds of switches. (Ethernet, Token Ring, ATM) Main purpose of VLANs is to limit broadcast (that's what most of us use it for but there are other uses like security). >From a design point of view and to keep it simple. At the access layer, each switch will have one VLAN. At the distribute layer you would have switches with RSP in it. It will function as the security, switching/routing between the VLANs. At the core layer, you can have only switches. All broadcast had been stop or change to unicast at the distribute layer. In a WAN situation, those switches could be ATM. If you have no broadcast in your network at all, you can do without the RSP and the VLANs. I am not sure how such a network would work but Howard or Priscilla can probability tell you. I hope this helps. A really good book to read about switching is CCIE Professional Development: Cisco LAN Switching.

RE: Switches !!!
Title: Switches !!! A.1 If you want to telnet into the switch you should give the switch an IP address. This IP address should be applied to VLAN 1. "Administrative Interface" A2 The NIC on the PC will broadcast their MAC address to the switch. You're getting the correct picture. However, if for some reason you are not being able to communicate between both PC's you need to check the port assignments on the switch. All ports should be assigned to VLAN 1 by default. If the ports are not asigned to the same VLAN they are going to be on seperate broadcast domains. This means that in that case you'll need a router to do the job. I try to be as simple as possible.

RE: Switches !!!
Think of the RSM as a router that just happens to be inside a big switch. It can run routing protocols (OSPF, EIGRP) just like an external router can, which means it can make routing decisions without the aid of an external router. This also means it can make the initial routing decision for MLS and from then on the switch can start forwarding packets. /Jared -Original Message- From: Jeffrey Humphreys To: Odom, Sean/SAC; 'Frank Wells'; [EMAIL PROTECTED] Sent: 8/12/00 10:53 PM Subject: Re: Switches !!!

RE: Switches !!!
I don't believe this is correct. "Layer 3 switching is hardware-based routing. In particular, the packet forwarding is handled by specialized hardware, usually ASICs. Depending on the protocols, interfaces, and features supported, Layer 3 switches can be used in place of routers in a campus design... Cisco's Layer 3 switching implementation on the Catalyst family of switches combines the full multiprotocol routing support of the Cisco IOS software with hardware-based Layer 3 switching. The Route Switch Module (RSM) is an IOS-based router with the same Reduced Instruction Set Computing (RISC) processor as the RSP2 engine in the high-end Cisco 7500 router family. The hardware-based Layer 3 switching is achieved with ASICs on the NetFlow feature card. The NetFlow feature card is a daughter-card upgrade to the Supervisor Engine on a Catalyst 5000 family multilayer switch. " This from http://www.cisco.com/warp/public/cc/so/cuso/epso/entdes/highd_wp.htm Also, from the BCMSN course notes, "An alternative to using a layer 2 switch and a layer 3 router is to use the next generation of LAN switches, called layer 3 switches. These new switches integrate layer 2 and layer 3 functionality in a single box". My understanding is that an RSM/RSFC/MSM is a full-featured router on a card. If it swims like a duck, flies like a duck, and quacks like a duck, I don't care if it's called Layer 3 switching. As far as I can see, it's just missing a few tail feathers in the form of WAN interfaces - it can still fly like a duck, just not over long distances :-) JMcL -- Forwarded by Jenny Mcleod/NSO/CSDA on 14/08/2000 10:27 am --- "Odom, Sean/SAC" <[EMAIL PROTECTED]> on 12/08/2000 03:03:10 am Please respond to "Odom, Sean/SAC" <[EMAIL PROTECTED]> To: "'Frank Wells'" <[EMAIL PROTECTED]> [EMAIL PROTECTED] cc:(bcc: JENNY MCLEOD/NSO/CSDA) Subject: RE: Switches !!!

The Catalyst 4908G-L3 is a feature-rich switch with full Cisco IOS implementation that allows network managers to continue to administer and manage their networks as they do today while scaling their backbone bandwidths to gigabit speeds. The Catalyst 4908G-L3 supports all the routing protocols that are used today in mid-sized networks. These protocols include: * Interior Gateway Routing Protocol (IGRP) * Enhanced IGRP (EIGRP) * Open Shortest Path First (OSPF) * Routing Information Protocol (RIP) Versions 1 and 2 * Static routes * Route redistribution Now if this guy is an OSPF router, and therefore contains a full table of the network topology, why does it have to consult an external router to forward a packet? Doesn't it have its own forwarding table? I remain unenlightened, and appreciate clarification.

RE: Switches !!!
Great! Did you see the post by Howard? He summed up interVLAN routing very technically in-depth. -Sean Sean Odom, CCNP, MCSE, CNX-EtherII Coriolis/Sybex Author www.TheQuestForCetification.com E-mail: [EMAIL PROTECTED] One of the things that confuses this discussion is that "switch" is more a marketing than a technical term. Certainly "layer 3 switch" is a marketing term. There seems to be an assumption in this discussion that fastest is always best. No. Taking off my Cisco stockholder hat, cheapest that will do the job is best. Regardless of the vendor, routing has two distinct functions. Path determination builds the "routing table," or, more properly, the Routing Information Base (RIB). The RIB is what you see when you do a "show IP route." RIBs are optimized for updating by dynamic routing. Incidentally, the OSPF database, BGP Adj-RIB, etc., are not part of the RIB, but are inputs to it. Typically, the first packet to a destination must go through the RIB to get the FIB set up. From the RIB is derived the Forwarding Information Base (FIB), which the second function, packet forwarding, examines to select the outgoing interface to which the packet is to be sent, based minimally on destination address. In process switching, the RIB and FIB are the same data structure. There is no true FIB. In fast switching, there is a FIB, which still is in main RAM, and forwarding is done by the CPU. In autonomous and silicon switching on the AGS+ and 7000, the FIB was in a separate memory, and the bus controller (AGS) or Silicon Switch Processor (7000) did the forwarding. The FIB was on the same board as the forwarding engine. FIB memory was small, so if the particular destination was not present (i.e., new or not recently used), there could be "cache misses". On a cache miss, the FIB was invalidated and rebuilt from the RIB. In optimum switching, the FIB and RIB are both on the RSP card, but in separate physical memories. One processor/memory set does path determination, and one does forwarding. In distributed switching (CEF and NetFlow) on router platforms, simplifying slightly, there is one RIB but multiple copies of the FIB are distributed onto the VIPs, each of which runs a separate forwarding process. VIPs have large memories, so the FIB and RIB (at least in CEF) are in 1:1 correspondence, and there are no cache misses. Still, the first packet to a destination goes through the RIB. In distributed/layer3 switching on "switch" platforms, there remains a single route determination engine. This can be in the same physical chassis (e.g., RSM in a 5000), or in a separate chassis (the "external router"). A Cisco proprietary protocol transfers the FIB information to a NFFC on a 5000 series or to a forwarding board on the higher-speed distributed switches. Using an external router platform as the source of the FIB, or even using an external router for all inter-VLAN routing, is simply a design choice. A very real-world situation is having your clients in one place and servers in another, but on the same VLAN (or using VLAN-aware NICs). In such a situation, the actual requirement for inter-VLAN forwarding may be limited to management (e.g., pinging from the management station) or perhaps email. The function of routing is important, but not the speed. In this case, to keep costs low, I'd consider, in order, 1. Use a 2600 to do all inter-VLAN routing 2. Use a 3600 to do it a little faster 3. I don't know the most recent support for external path determination -- used to be that the 4500/4700 was the lowest platform. Probably a 3600 can these days. Use a 3600 as path determination engine and an NFFC or equivalent on the switch platform(s). 4. Use an RSM/NFFC or equivalent. 5. Use a 1/12000, etc., for very heavy routing loads with multiple WAN interfaces.

Cisco's counterclaim was that VIPs cost less and were more optimized for forwarding. In the newer platforms from both vendors, there really is convergence.

Things get even more complex, and there are no simple answers, when one considers more processing-intensive functions like filtering, traffic shaping, encryption, compression, etc., and whether these are in the "fast path," a coprocessor, or the main processor. I'm sure you will see both similarities and differences in new products from all vendors. ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

hmmm. in the aforementioned new Cisco CDs I just got there is a "8 Minute Layer III Switching QuickStudy". The interesting thing it points out between differences in using a router to route or a switch to "route" is that routers have RISC processors and switches have ASICs. It goes on to say that the RISC is more powerful and meant for doing other things like encryption, handling WAN traffic, etc - whereas ASIC does forwarding only.

RE: Switches !!!
>From the Cisco website: http://www.cisco.com/warp/public/cc/so/cuso/epso/entdes/highd_wp.htm watch that wrap :-> Layer 3 switching is hardware-based routing. In particular, the packet forwarding is handled by specialized hardware, usually ASICs. Depending on the protocols, interfaces, and features supported, Layer 3 switches can be used in place of routers in a campus design. Layer 3 switches that support standards-based packet header rewrite and time-to-live (TTL) decrement are called packet-by-packet Layer 3 switches. High-performance packet-by-packet Layer 3 switching is achieved in different ways. The Cisco 12000 Gigabit Switch Router (GSR) achieves wire-speed Layer 3 switching with a crossbar switch matrix. The Catalyst(r) family of multilayer switches performs Layer 3 switching with ASICs developed for the Supervisor Engine. Regardless of the underlying technology, Cisco's packet-by-packet Layer 3 switching implementations are standards-compliant and operate as a fast router to external devices End quote. But also look at this: http://www.cisco.com/warp/public/784/packet/july98/12.html The primary difference between the packet-switching operation of a router and a Layer 3 switch is the physical implementation. In general-purpose routers, packet switching is typically performed by microprocessor-based engines. A Layer 3 switch performs packet switching with application-specific integrated circuit (ASIC) hardware, which enables greater raw throughput. Although higher-speed packet switching would seem to offer obvious benefits, a common but flawed assumption is that it will automatically improve the speed of applications. For example, if application demand on the network is 10,000 pps, and current Layer 3 devices process packets at 200,000 pps, replacing them with devices that perform even at 10 million pps will not speed up the applications. Raw performance, therefore, is not the most important criterion for selecting a Layer 3 switch. Route processing and intelligent network services -- two vital software functions -- have a more significant impact on the performance of specific applications and the network as a whole. End of quote Note the caveat, from Cisco's own mouth, as it were: layer 3 switching cannot be assumed to automatically improve network performance. This continues to be a wonderful thread, one forcing me, at least, to push the envelope in my studying.

There is a very widespread misperception that routers and switches impose significant latency. At one time, this was true.

Re: Cisco switches or HP switches? Which to buy?
Remember - you may not be saving money by buying less expensive hardware with the same functionality. You need to factor in the support available, the reliability of the hardware, the uprgadeability, managability, etc., etc. You may save several hundred dollars on a switch but that does not add up to much if your network is down for several hours because of reliability issues. I do not have firsthand experience with the HP line if switches so I am NOT implying that their hardware is unreliable.

RE: Cascading Switches
Hub-n-spoke is not always practical from a budget perspective. I think of cascading and stacking as basically the same thing in terms of physical topology. Creating a switch cluster (stack as you call it) simply provides a single management interface for the entire cluster. A cluster does not need to be a physical stack of switches, however, as they can be spread out across the LAN. Now, when it comes to the maximum number of switches that you can stack, that depends on the technology involved. There are distinct limitations to each. With Cisco's GigaStack GBICs, you can stack up to 9 switches in half-duplex mode. You could also simply use crossover cables between the 10/100 ports, but the stack size limitation is probably different when doing this. In comparison, 3Com's matrix module only supports a stack of 4 switches within the shared backplane. As Gareth suggested, hub-n-spoke is a better way to go, but you should dedicate a switch just for the hub function and then uplink all of the other switches to it. This way, you prevent frames from crossing the entire backbone and going through every switch, which could happen in a stacked configuration. A little more expensive, but better in the long run.

I've heard there is a way (command or two) that will allow me to manage these switches as if they were enterprise. Does anyone have any ideas?

IBM ATM Switches
Hi, Does anyone know about the IBM ATM switches. Specifically the 8285 ATM switches, I believe are the lower end ATM switches. Is this sufficient for an ATM switch for a home lab? I'm not too familiar with ATM product range. I believe there is an ATM module for the Catalyst 5000, so does that make it an ATM switch? What about the Cisco LightStream products, are they no a switch as well? Is setting up ATM in a home lab a matter of getting the right module for the router, and hooking it up to the switch?

Training on switches.
I am trying to find aresource to get some training on Cisco Switches (2900's thru 5500's) for some people at work. Something on CD would be best. Perhaps something like Learneky offers.

Hubs and switches...
If you have 5 Hubs attached to a Cisco Switch, will the switch add every MAC address that touches one of those Hubs to it's ARP table?

Re: Cascading Switches
Hi, I can't find my figures but off memory you can have 5 bridges between 2 devices therefore you could have up to 5 switches between two clients or client -> server. This would probably suggest the to go more than 3 deep in your cascading could present a problem but could the links cope. Running 15 or so switches into another with a couple of servers into it would be ok. But running 15 or 20 into one switch then onto another 15 or 20 I guess you would end up with a huge bottle neck if not between switches then most likely at a server. 20 X 20 is alreay 400 connections, whew!. Just some thoughts. Teunis Hobart, Tasmania Austalia On Monday, January 22, 2001 at 04:49:30 PM, Maness.

Re: cisco switches
True Percilla, but I would rather hire someone who could actually make the switches do what he knows they can. Also, the BCMSN had around 5 or 6 command questions, so it wasn't just the CLI that got him... ;) P.S. Love your book ;) Mark Z ~ CCNA/DA 1/4-NP **NOTE: New CCNA/CCDA List has been formed.

Re: cisco switches
Oh yeah I just remebered I got a 934 on that switching test my finger got stuck. I'll scan it and post if anyone doubts it. I know there was a chuckle there, bordered on belly roll. Bingo priscilla if you know what vlans are and multicasting is a STP is HSRP is My mother says: Donald time for dinner My brother says: yo duck lets eat My father says: Buddy-Boy don't make me call you again!! either way i get my belly full cause I understand that concept of dinner. all those commands work. what do you think i,m brain dead i wouldn't tell anybody if I got a 347. I'm not going in there with a Jedi send in a droid. Pricsilla thanks for coming to the defense of all those that turn it on and make it work. Looking forward to reading your work, it is on my reading list and about fourth in the queue. Working on Doyle right now. I'd shoot you a resume but I got a good ride right now. I apoligize to the group but I don't think cisco even cares which runs on which, that's just extraneous stuff that you read in study guides. If the test is truly adaptive I'd give a question like that a one, and a question about routing between VLANS or configuring a router for a dense-mode network a tad higher in the score count.

Re: cisco switches
See what I'm talking about. You don't get 300 points. That attitude is not the good attitude Neil. I was joking you guys are serious you think you get 300 points. No. That is just a scale in the adaptive testing format. You mean to tell me if you answer 1 question right get a 333 you are 1/3 of the way to a 1000.

Re: cisco switches
Test taking skills and real-world skills sometimes overlap and are related but not always. I've met scores of people who are excellent at taking and passing tests of any kind, but have spent most of their lives in a classroom and have little high-pressure real-world experience. In that light, I tend to regard someone who has passed a computer-based test as someone who has the basics of a subject memorized, which is often the first step in an apprenticeship. However, there are many people who have lots of hands-on experience who can't ace a CCNP/CCDP test because they aren't good at tests or haven't studied the test material (very little of which you really need to have memorized in the real-world to do your job). I passed all those CCNP and CCDP tests a couple of years ago and remain somewhat disgusted about how much useless nonsense I had to memorize. On a daily basis I would say I use less than 10% of the test material in my job as a network engineer. Jonathan Priscilla Oppenheimer wrote: > > Yes, but in the real world, I like Duck's attitude.

Re: cisco switches
Well last time I checked this was a study group. And Cisco might care for their tests. So, it might be a good idea to know the difference. Its not that hard. I believe 4000 and up run switch IOS and everything below that is router type IOS.

Switches and VLANs
hi olzak! I have a question. How can a pc in VLan 2 reach to a pc in Vlan 3 without hitting a router? As far as I know, router would interconnect different Vlans.(in your example, Vlan 2 and Vlan3). I mean, is it possible not to use a router to connect different Vlans, because it can be done using Multi-Vlan function on 2900XL version? I will appreciate your reply. jeongwoo __ Do You Yahoo!?

Connecting Switches, hubs..
I have a simple question, and one which I cannot readily answer at this time. Can I safely connect TWO switch ports from a Cisco 5509 (two different switch blades) to a hub to increase the hub's crossconnection bandwidth, without having a looping problem? The hub is actually a DEC multi-blade, with a swithced backplane. The hub is also connect on two different blades, but the same backplane. TIA! btw, I have already done this and I figured if spanning tree found a looping problem, it wouldv'e set one of the ports to a non-forwarding state.. ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: cisco switches
I disagree. From what I have seen Jason is 'learning the ropes' in an organized and focused manner. IMO, he asks good questions and typically only after researching and reaching an impasse, this time being an exception. He is also one of the more active posters on the list in the time I have been subscribed. I have benefited from many of these threads. That said, the question you are responding to could be answered with a polite link to www.cisco.com .

Re: cisco switches
who cares!!! when you console, or telnet, or tenlet in you will find out which command set you are using. If you know what a switch can do you should be allright.

Re: cisco switches
Yes, but in the real world, I like Duck's attitude. Basically he's saying that he doesn't need to memorize which switch has IOS. He is not intimidated by any switch because they all basically do the same thing, and he has learned enough configuration commands in both command sets to feel comfortable. I could see hiring such a person even if he did flunk the test!

FS: ATM LANe Switches
Hey guys. If anyone needs LANe switches, I've got two I'm selling for cheaper than a LS 1010. I no longer need them. 1) 3Com Corebuilder 3500 [ http://www.3com.com/solutions/cb3500.html ] This is cool because it's a Layer 3 switch, six 10/100 TX ports, six 100 FX ports, two ATM OC3 Multi-Mode fiber ports, runs RIP v1, RIP v2, and OSPF, QoS, LANe, etc.. I also have a 3Com Switch 3300 with 100FX uplinks if you need to practice 802.1q with your Cisco gear. Both include rack ears. 2) 3Com Corebuilder 7000 [ http://www.3com.com/products/dsheets/400265.html ] This is a large core switch with sixteen 100 TX, sixteen 100 FX, and sixteen ATM OC3 Multi-Mode fiber ports. Includes rack ears, redundant power, redundant sup modules. I'm asking $900 for each one. This includes shipping (and they are HEAVY! Probably $100 to ship each one). I'm not making money off this, just trying to get back what I invested. So hopefully this will be beneficial for some of you.

Re: IBM ATM Switches
The LightStream is Cisco's ATM Switch and good. It's pricy though and may be hard to find. IBM. I'm familiar with the MSS products (don't know part # but it is 82xx.. may be 8285). The MSS were OEM'd from Xylan. IBM OEM'd some of their switches to. The MSS has a very cryptic configuration. The Cat 5000 ATM module is for LANE. Not switching. You might be able to pick up some older FORE gear for ATM switching at a decent price. FORE was known for ATM and still is. You can also get ATM modules for each router and do back-to-back ATM.

Re: IBM ATM Switches
The IBM 8265 is a good switch. It was not OEMed from Xylan (that was the IBM 8274 / Xylan Omniswitch) with the 8265 you would also need the MSS for ATM/LANE configurations. There is a config tool available for both and it actually looks like the 2216 router config tool, with the addition of Switching, ATM, and LANE added to it. Same look and feel.

Arrow Point content switches
Group, Our company is considering using the new Cisco / Arrowpoint content switches. I have been informed that there management connection is not routable, and as a result transmission of any packets from the switch to a remote management station on another IP sub net is not possible. The management station must be on the same IP network. Can anyone confirm that this is true ? And has anyone found a solution to this problem ? I have been thinking about the use of IP helper addresses, but i am not convinced that this will work. Other thoughts have gone down the procy route but i feel that these will lead down a black hole. Unfortunately we have no spare kit to get this tested in a lab.

Re: Hubs and switches...
The tricky part of the question--and I think someone touched on this before--is that a managed switch is going to have an ARP table and a CAM table, and they're completely different animals. The ARP table is used only when the switch itself is communicating with other IP devices. It will send an ARP request and place any responses in the ARP table. The key is this: the ARP table matches an IP address to a MAC address. The CAM (Content Addressable Memory, IIRC) table is what correlates destination switch ports with MAC addresses. If the switch receives a frame from a device, it places that device's MAC address and incoming port # into the CAM table. The key: the CAM table associates MAC addresses with switch ports.

Cisco vs. HP Switches
We are looking at four new 24 port switches for our network. We have Cisco and HP as our final contenders. Both the HP Procurve and the Cisco Catalyst carry similar specs, but the HP is about 20% of the cost of the Cisco. Can someone give me a REAL reason why the Cisco Catalyst would be a better choice. Our network is all 10/100 for now and we won't need Gigabit for at least a couple of years. We need these switches to be in 24 port configurations as the company is going to split in two in a couple of months and move half of the operations to another building, so we need to be able to split the network as needed. I know this is a Cisco group, which is why I am asking it here, because I want a BIASED opinion of why Cisco would be better in this situation. Thank you all for your suggestions. Denis Denis A.

Upgrading to Cisco switches
I am upgrading my network from Bay/Compaq/Misc. switches to Cisco switches. I heard a rumor...in order to connect a Cisco switch (from a wiring closet) via fiber (GBIC) the core switch must also be a Cisco. In other words, a Cisco switch when connecting via fiber can only connect to another Cisco switch. I find this hard to believe, but I want to make sure before I go spouting off. Thanks in advance.
Re: Telephone Switches --> --> --> PA
The company I work for uses Lucent switches internally (we're an eCRM company much involved with online banking, dotcoms, etc. - what used to be called call centers). I know that Lucent offers classes on their switches and have a certification on running their switches in a call center environment. Depending on what brand switch is used by Verizon in the local COs, you might want to check that manufacuturer's website for training. A few phone calls to your local Verizon office should tell you what switches are being used - mostly AT&T in my area - Northern West Virginia/SW Pennsylvania. You'll have to talk your way past the CSRs - Customer Service Reps - to talk to the Engineering people but, once you do that, if you explain what you're after, they may be able to point out training resources that will help you out.

Segments, Switches, and Routers
If I have 2 segments each connecting to a Catalyst 5000 (via GBIC fiber) in the core, do I need a router? The more I think about this, the more confused I get. Should I put in a couple of 4908G-L3 in the core? I guess I don't understand when I have to and when I don't have to use a router when connecting seperate subnets through (or using) a layer 3 switch. I understand what a layer 3 switch is, but I am confused on when I really need to use one. If I was to subnet a class B address in to 8 subnets, would I use a layer 3 switch, like a 4908G-L3 or a bunch of routers? I thought in a proper Cisco design, layer3 activities should be done at the distibution layer and not in the backbone.

HSRP Between 6509 Switches
Could someone tell me if they have seen this problem before or have any suggestions. Scenario: We have 2 6509 switches with msfc cards in each on the 1st floor and 4th floor of a building. We have redundant links between the switches and each switch has redundant sup 1 cards with the msfc blades. We also have 2 more 6509 switches on the 2nd and 3rd floors of the same building. The first floor switch is connected to the outside world through a 7206 router. There are multiple vlan across each switch that are connected to the user through several 3500 series switches on each floor. When we first turned HSRP on, the msfc1 vlans did not come up. We get Cisco online and they said we had a bad msfc card. So we switched over to the redundant msfc card (msfc2). The vlans came up and hsrp between the switches was working (exchange hello packets and send standby info). Each vlan knew of the other vlan standby router and ip address. To run a test we disabled our connection to the outside world to localize any problems and brought up continuous ping sessions between the switches and vlans on the 1st and 4th. Next we shut down the 1st floor switch. (Note: The 1st floor switch has the higher priority). The network went down and hsrp did no swap over to the standby switch. Additionally, when we disconnect the cable between the 1st floor and 4th floor switch we see duplicate ip address errors. We saw the same duplicate ip errors the last time we disconnected the cable between the 1st and 4th floor switches, but that was before we had hsrp installed. Some other useful info: About 3 weeks ago, before we installed the 1st floor switch the 4th floor switch acted as the interface to the outside world through the msfc card that cisco now says is bad. Then we installed the 1st floor switch and move all connections through the 1st floor switch. Essentially the 1st floor switch became the interface to the outside world with redundant link to the 4th floor and 2nd floor switch. When we did this the vlan could not talk to each other. Which means that we could ping the msfc card from the outside world but not the 6509 switch. Internally, we could ping the 6509 switch, but not the outside world. To isolate the problem we removed the connection to the 1st and 4th floor switches like we did above and everything came up, but we saw the same duplicate ip address errors. We did a hardware reset of the switch and reconnected the 1st and 4th floor switches and everything started working correctly. Any ideas? This make no sense to me and installing HSRP should not be an 8 ordeal.

RE: Renting Routers/Switches
I think you'll find renting then prohibitively expensive. What a lot of people do is buy what they need on e-bay or through used vendors, and when they're done, resell the equipment.

Switches/cables [7:3673]
I looked at my G4 mac and the Apple System Profiler says 100Mbps/full duplex. The 3548 XL switch says 100Mbps/full duplex.
