Re: CCIE Writen Failed again
I really don't think the survey would have anything to do with your score. I would find that very hard to believe that Cisco would punish people for not filling out a survey...however I would find it more then natural for them to punish people by not knowing the material by flunking them...

Re: Serial over Ethernet
OK, I see you want to conserve IP addresses, so what you need to do is use private address space on the ISL subinterfaces and then perform nat on the router to the public IP's.

If PAT will work for you, use the serial's IP address with NAT and use the OVERLOAD command. I hope this makes sence, I don't have time to give you an example.

Re: setting mtu size on a 2611
I'm coming in on the middle, so this point may have already been made: You should do the fragmentation and interleaving at the datalink layer with FRF.12 or multilink PPP. Don't set the MTU on the interface for the following reasons: It will cause IP to fragment. The packets will remain fragmented until they reach the end-node recipient. This causes extra work for the recipient. In addition, it's silly to have fragments on the other end if the other end is a Gigabit Ethernet, for example. With FRF.12 and multilink PPP, the partner router reassembles at the datalink layer. Some protocols, such as AppleTalk and IPX, don't have a fragmentation and reassembly function. Setting the MTU to a small size simply breaks those protocols. Priscilla At 11:22 PM 6/19/00, Chuck Larrieu wrote: >Eric, I wanted to follow up on this one.

Newbie trying to build a lab
Hi all, I have been lurking while I learn more about the Cisco product line and this world of networking. I am trying to build a lab so that I can practice some of the things in my CCNA book. I could use some advice as how to place it all together. Types of set ups that would be helpful, cabling issues, where to obtain additonal cables etc. I currently have 2 routers 1 is a 2501 and the other is a 2503. Any URLs and\or advice would be helpful.

I just passed the Support 2.0 test with a score of 873. There were 61 questions, 692 required to pass. The test had some confusing questions, but it wasn't too bad. It did not have the technical detail I expected, but it still required very in-depth study. I used the CIT 4.0 course book, the Exam Cram book, boson #2, Priscilla Oppenheimer's flash cards, and threads on this list.

Re: ip and subnet
This won't work because the subnet for the first floor includes the addresses you are then trying to assign seperately to floors two and three. You first floor subnetwork includes addresses from 10.150.0.0 - 10.150.255.255. So, any traffic from floor one to floors two or three will not be sent to the router because the source will assume, given its address and mask, that it exists on the same network as the destination. The router won't know where to send traffic from floor two bound for floor three, since addresses in the 10.150.102.x range could be on floor one or floor three. Same for sending from three to two. Will the router even let you set this up this way? I've never tried. Maybe it would assume it was dual homing and would try load balancing between the floor one and floor three interfaces, giving intermitant results when sending from floors two or three. Stick an extra 8 bits on the subnet mask for the first floor, and allow ip subnet-zero, and it should work. ---JRE--- ""SH Wesson"" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > If on one floor I use 10.150.0.0 255.255.0.0 and on the remaining 2 floors I > use 10.150.100.0 255.255.255.0 and 10..150.102.0 255.255.255.0, will this > work in terms of all three networks being able to communicate with each > other.

Re: Firewalls
You'll probably want to look up performance stats with Cisco and Checkpoint directly, although I would doubt that Checkpoint is faster. Can someone else with more experience on PIX hardware jump in with more information? You also have to look at the cost perspective. Ok, maybe Checkpoint running on an E450 or an E3000 will be as fast as much less hardware/cost in a PIX solution. But, do you have the extra rack space to lug one of those Sun boxes in? Do you have a hired unix admin to take care of the box when it goes down, or needs general maintenance/upgrades? Sun reps can be expensive. In general, hardware based firewalls are always going to be faster. I've worked a lot with the netscreen 100 devices that are mostly hardware based, cost about $10,000 and use 100Mb ethernet ports on all sides. They perform very well under a wide variety of traffic loads, although I've never pushed more then 70Mb/s through it. Using a SmartBit to max it out isn't always the most realistic of scenarios either. Netscreen claims that their hardware adds very little (microseconds) latency, but again, this is all in their labs using only SmartBits. I haven't measured realistic latency myself. Ok enough firewall plugs.. I'd really suggest going to the NetworkWorld trade journal site http://www.networkworld.com and searching for firewalls in their archives. They do routine performance evals of every major platform out there.

Re: Off Topic - Technical Review, OR What do I know? :->
A Cisco editor would have caught that! ;-) It means prioritize SNA before e-mail, i.e. SNA is higher priority than e-mail.

Re: Serial over Ethernet
Tony, I am very short of IP addresses and wanted to reduce public IP utilization by 75%. PPPoE is not supported on my routers (I have c26xx). Here is the story - the router will provide internet access to many workgroups located on different VLANs. I am running 802.1q (switch is not from cisco) encapsulation on router subinterfaces.On each VLAN I will have third party NAT boxes, so they need 1 public IP address. I was thinking to save 3 IP addresses on each VLAN, if this is possible at all, of course. If I can "emulate" ethernet sub-interface as serial, then give "unnumbered", the solution looks pretty straightforward... I want to use rate limit on subinterfaces too.

PPP Multilink question
Hi all, I hope someone can help me understand something about PPP multilink. I was reading up on it, and checking the routers at my job to verify that it was working. Whenever two routers have a dial connection using BRIs and they are configured to use PPP Multilink (PPPM), they work fine and the command "show ppp multilink" gives me info about them. We have a 3640 with a PRI that a bunch of local routers with BRIs use for dialup. The BRIs are configured for PPP multilink, but the PRI is not. Over the weekend I tried getting it to work. I have also read several articles on CCO and read the section in ACRC on PPPM, but have found no configs for PRI and PPPM. So, I think that it probably cannot be done, but I am not sure why. My two questions: 1. When the local routers call up and bring up two B channels, they are not using PPPM. How does the data flow differ in this instance from a PPPM connection? 2. What is different about a PRI that does not allow the PPPM to be configured?

Re: Memory Calculation
You will find that such a formula will require the specific IOS, feature set available, feature set used, routing protocol(s), interfaces, sub-interfaces, the phase of the moon at installation... (Actually you might not need sub-interfaces! ;) Every formula I have ever seen fails miserably - the one for EIGRP from Cisco reported that 1.5 MB would be enough - we died with almost 40 free before the installation. Basically, if you are going to do BGP, EIGRP or OSPF I'd max the memory - its cheap. Also, NAT, PAT, access-lists and other features would tend to influence my desire to load things up. Just as with PCs, you're best bet is to have enough. Otherwise, make a best guess, load it up and take a look - baring in mind that new features may put you over the top. --- Masaru Umetsu <[EMAIL PROTECTED]> wrote: > Hello,all ! > > I have a question regarding a memory calculation. > When I buy a Cisco router,I have to make a > calculation of memory(DRAM) > of Cisco router.

No this will not work, tell us what will happen when a user on floor 1, let's say his ip address is 10.150.25.25/16 tries to ping a user on floor 2 whose ip address is 10.150.100.25/24. The ping will fail, but you need to know why in order to understand why this ip scheme will not work. By the way, if you are using a private address, why are you choosing an addressing scheme like this anyway.

RE: collision on cut-through switch
Not a white paper, but let's see whether *I* understand how it's supposed to work Cut-thru waits for the dest addy, then starts forwarding. Frag-free waits for 64bytes, then starts forwarding. Store'n'forward waits for the whole packet and CRC's it, so will only forward truly valid (tm) packets. Sooo... cut-thru will forward runts, and you'll get those if there's a collision after the dest addy but within the first 64. Frag-free will /not/ forward runts, so will protect you from collisions that really should have happened. It won't protect you from 'late collisions' (that shouldn't have happened), but you're gonna fix your cable plant to remedy those (aren't you? :-) Or am I lying ? :-) (big quote for context, below; sorry) Tone > From: Barry Hofland [mailto:[EMAIL PROTECTED]] > Hi, Priscilla, > > I think the best way to find this out is to just get yourself > a network > tester to connect between the transmitting host on port 1 and > the CISCO box. > ( like a FLUKE ) You will be able to see ( or not ) the JAMS > on port 1.

Re: ip and subnet
The way you have it setup means that 2 and 3 floor won't be able to talk to eachother, but the 1st floor will be able to talk to both of the other floors, 2nd and 3rd floor will be able to talk to some hosts on the 1st floor, plus there is a chance of overlapping addresses if your not careful. If your goal is have all the floors to talk to eachother, a better way to subnet it would be: 1st - 10.150.1.0 255.255.0.0 2nd - 10.150.2.0 255.255.0.0 3rd - 10.150.3.0 255.255.0.0 This way all floors are in the same subnet therefore they can all see each other.

If I have misunderstood this, anyone, please correct me .. I've spent over a year trying to understand exactly how this works. =) I'm hoping they put some new 12-releases out soon; I just had to upgrade to 12.0(7)XK1 to support some new NMs we purchased, and it's got some .. interesting quirks to say the least.

IP Addressing
I currently have one floor where my routers and servers are. These are address as 10.100.1.x and 10.100.2.x addresses with a subnet of /16. I'm adding two more floors. However, in adding two more floors can I address these floors as for instance 10.100.11.x, 10.100.12.x, 10.100.13.x, and 10.100.14.x with a subnet mask of /24. I'm confused as to how this may work if I have them all at a /24 subnet mask, a /16 subnet mask in the current floor and /24 subnet mask in the new floors, or even changing everything including the existing floor and new floors all to reflect /24. Any help with this ip address stuff and how the new floors can be integrated would be greatly appreciated. Thanks.

Re: collision on cut-through switch
Without doing any research and only depending on the seat of my pants, here is what I believe. In a cut-through environment, the switch will only buffer the necessary portion of the frame that is necessary for it to know where to switch the frame to. It doesn't care if the frame is a jumbo or not, a collision or not. Therefore if a packet is received destined for the broadcast address and the header is in tact and looks completely correct, yet the packet is hacked all to hell because of a collision beyond the header information, this collision will be broadcast to all devices. In a store-and-forward environment, the switch buffers the entire packet and handles error conditions so that end-systems do not have to be interrupted in order to process erroneous packets. I believe that on a number of switches, they can be configured as cut-through with some extra checking. Should a port be receiving a large number of erroneous packets, they will reconfigure themselves on the fly to store-and-forward in order to guarantee the highest throughput possible. These are just my quick thoughts, I'm sure a little research would lead to a more fully-qualified answer. But, you get what you pay for.

If it's ED, you may want to down/upgrade to a GD version. Let me know Russ..

Re: Backup Interface
You need to configure the backup interface from the serial interface ie: router# int s0 router#(config-if) backup interface bri0 router#(config-if) backup delay 20 40 or router#(config-if) backup interface dialer1 router#(config-if) backup delay 20 40 It would probably be better to use a Dialer interface instead of using the BRI interface directly.

The first question is has it ever worked, if yes, then what changed since it last worked, either on your network on the account, confirm with your ISP that the Zone file us still properly set up and that it has not changed. You should be able to telnet to the pop3 account on both ports (25 and 110) if not, it could be a firewall problem (More than likely) if you are behind a firewall or router configuration i e access list et all or that the account is incorrectly set-up or non assistance.

ccda
Hi to anybody taking the CCDA. I took it recently and had a shock when the exam flunked out after 7 questions. (I guess corrupted files on the transfer)? Well the point is after a 30 min wait for a second download the 2nd exam was a completely different format than the first. The first exam had 88 questions with marking capability, the second had (i think) 77 and NO marking capability.First question was a scenario as i was jittery it was a bit unnerving not being able to mark and go back. So presume nothing, please no emails for questions.

I'll elaborate, the dialer brought up BRI3/0 and BRI3/1 and made the 4 calls one after the other like it should and bound them into a virtual interface but then the dialer started reporting errors saying LCP not open when all 4 channels did successfully negotiate LCP and both they and the virtual bundle showed LCP open. The Dialer showed spoofing. The end result no pings or traffic was working across the link. Downgraded the IOS and it all started miraculously working again!

RE: collision on cut-through switch
Looking at this logically, I don't see how Cisco would not allow for this. A fundamental function of a bridge (besides a layer 2 forwarding decision) is to re-establish the slot time, thus making it a collision domain boundary. If cut-through-switching negates extending the network diameter in the name of speed, what's the point? Jay Dunn IPI GrammTech, Ltd. 210.694.4313 http://www.ipi-gt.com Nunquam Facilis Est -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Priscilla Oppenheimer Sent: Monday, June 19, 2000 3:47 PM To: [EMAIL PROTECTED] Subject: collision on cut-through switch Hi Group Study, I got into a discussion with a knowledgeable Sniffer instructor recently. When he teaches cut-through-switching theory, he warns his students that a cut-through switch does not really isolate collision domains. Consider this example: * The switch is receiving a frame from port 1 destined for a station out port 2. * The switch recognizes the destination address and starts forwarding the frame to port 2 ASAP. * There is a collision on port 2. (It's a shared and/or half-duplex Ethernet.) According to the instructor, the Switch sends a jam signal back to port 1 to let the initial sender know that the frame experienced a collision. This allows the sender to retransmit. If you read some of the books on switching, you would think that this is true. The books make it sound like the frame is passing through the switch and disappearing out the destination port as soon as the destination address is recognized. I don't think the Sniffer instructor's conclusion is true, however. I believe that a Cisco cut-through switch buffers the frame and hence has the ability to retransmit. There is no requirement to send a jam to the original sender because port 2 in our example retransmits after sensing the collision. I believe that Cisco switches store frames, even when doing cut-through, whereas the instructor assumed that the frame has passed through and out the port and is no longer available for retransmission by the switch. Cisco positions cut-through as reducing delay, not reducing the need for buffering, so I'm contending that I'm right. Who do you think is right? Can you point me to any white papers that would prove who is right?

trace pop3?
we have a funny problem from our small network. None of us can Receive mail from a certain mail server that we use at a remote location. We can however send mail, using accounts based on that server. We can telnet to port 25 but NOT to 110, on the remote mail server. All indications are that this is a firewall problem. I have taken down acls on our office Router temporarily to check this at our side, but problem still persisted. Guys at the other side are 'sure' the problem does not lie with them, it could of course lie at our ISP, but extremly unlikely or? Would be grateful for any trouble shooting tips, to determine where the 110 pkts are being dropped thanks in advance tayta ___ 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]
CCIE ISP Dial study group
Does anyone want to form an ISP-Dial online study group??? I'm getting a few of the course manuals, but I'm looking for other post-CCNP level hopefuls that are a few months away from taking the lab... I just purchased an 804 on Ebay, now I'm selling it there... I have plenty of access to the other equipment at work (AS5200, AS5300, etc. etc.) I just need to get experience with the ASDL and cable stuff. Lets trade experience, course information, and lab stuff. I'm MOTIVATED! The main reason why I'm so amped is they keep adding stuff to the ISP-Dial cert... let's pass this before they add more! :) John
Re: Catalyst 6509 Giga EtherChannel- trunking
Sorry for something error in the chart. The VLAN between 6509s is VLAN20
with the same network segment. VLAN3 is divided into 2 for more services
reliability, but only one Gateway could be set here in one of the 6509 Switches.
So when the 6509 with the GW crash, VLAN3 still have to be shut down.
I think the VLAN3 could also be set to 2 VLANs so there needn't rely more on
the inter-link trunking. But sometime maybe it's not permitted. Could someone
give more analysis about the performance of trunking technologies?
