Re: Looking for async modem dialup config for ISP
Hi all, I wonder if Paul Lalonde got an answer for his question below because I'm also looking for something similar. Pls help, anybody ? Paul, I hope you are reading this. Regards I'm looking for an example configuration of async modem dialup from a Cisco router to an ISP. I'd like to get my router connecting to the ISP for test purposes. However, my ISP provides a text-based front end (Xylogics Remote Annex) which requires the username, password, and 'ppp' options to be entered. All of my existing DDR configurations work in a branch-office to central-office arrangement (when the IP address of the destination network router is known). But I can't seem to get dial-on-demand calls placed when the destination network is last resort (0.0.0.0) Any examples would be appreciated. Thanks!

RE: Off Topic: Citrix and PIX via Secureclient?
I assume you're talking about the ICA secureclient. I have not used it, but according to Citrix it does slightly degrade performance (vs. normal ICA). However, I can't see it being a serious degradation. For the PIX setup, the Citrix/ICA protocol works like most (e.g. ftp). It listens on one default static port and establishes a session on another from a range of available ports. As for a 56k connection, this shouldn't be a problem. I have a client whose technicians use Citrx to run a windows based client/server app from the field. They carry laptops and connect to a frame relay network via wireless modem. The wireless connections operate at 14k and the base host connects via a 56k lease line on a Cisco 1600. They're very happy with the performance.

Smart serial, and normal serial
Hello all, I am having a problem with a WIC-2T. The setup is as follows: A pair of HDSLs connected back-to-back. The clock is generated from one of the units internally, and the other unit receives this clock and uses it. When I connect a normal serial at one end to a smart serial on the other, I get a lot of errors on the serial interface in the frame counter. However when I connect normal serial at both ends, everything works fine... Do I have to put a certain commend on either interfaces to work On the other hand the same card WIC-2T is working fine with a 128k circuit using NTUs connected to a TDM MUX, with normal serial on the other end also Regards, - Hossam El-Ashkar [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Equal cost switching
Jason is right. This will defeat the purpose of Spanning Tree of creating a single path to a destination. The primary reason this was designed was to prevent broadcast loops. If you want to force it to use 2 paths to one destination, use port-channelling which statically load-balances traffic going out of two ports. Statically meaning it creates a list of source-destination MAC address pairs and these pair will communicate from a specific port configured to be part of the port-channel. This is in contrary to Dynamic load-balancing where each packet will go out of each port of the port-channel. With this in mind, if 4 ports are configured for 100 Mbps full-duplex port-channels, this doesn't mean it provides an 800Mbps link. "AndyD" [EMAIL PROTECTED] wrote in message 96p2uk$rt5$[EMAIL PROTECTED]">news:96p2uk$rt5$[EMAIL PROTECTED]... Spanning tree is supposed to choose the one best switched path.

Re: Equal cost switching
I don't think you can put a single port on two VLANS unless you configured trunking if my memory serves me right. with Per VLAN spanning tree a particular switch can belong to multiple instances of spanning tree and in each spanning tree instance, it might be acting as a root bridge, some ports might be in blocking mode or forwarding depending on what VLAN it belongs, too. I believe the design that you had drawn shows the access layer switches are trunking to Switch A and B to provide redundancy in case of failure in switch A or B. Also, each switch in the access layer can run up to 2 instances of spanning tree on each VLAN which are carried through the trunk ports only if Cisco switches are used.

This will defeat the purpose of Spanning Tree of creating a single path to a destination. The primary reason this was designed was to prevent broadcast loops. If you want to force it to use 2 paths to one destination, use port-channelling which statically load-balances traffic going out of two ports. Statically meaning it creates a list of source-destination MAC address pairs and these pair will communicate from a specific port configured to be part of the port-channel. This is in contrary to Dynamic load-balancing where each packet will go out of each port of the port-channel. With this in mind, if 4 ports are configured for 100 Mbps full-duplex port-channels, this doesn't mean it provides an 800Mbps link.

RE: what is VOIP ?
A few lines. Voice-over-IP (VoIP) enables a router to carry voice traffic (for example, telephone calls and faxes) over an IP network. Cisco's voice support is implemented using voice packet technology. In VoIP, the digital signal processor (DSP) segments the voice signal into frames and stores them in voice packets. These voice packets are transported using IP in compliance with the International Telecommunications Union-Telecommunications (ITU-T) specification H.323, the specification for transmitting multimedia (voice, video, and data) across a network. Because it is a delay-sensitive application, you need to have a well-engineered, end-to-end network to successfully use VoIP. Fine-tuning your network to adequately support VoIP involves a series of protocols and features to improve quality of service (QoS). Traffic shaping considerations must also be taken into account to ensure the reliability of the voice connection. regds Hp -Original Message- From: Robert Nickson [SMTP:[EMAIL PROTECTED]] Sent: Monday, February 19, 2001 2:47 PM To: [EMAIL PROTECTED] Subject: RE: what is "content distribution" ?

RE: HSRP and UDP forwarding.
Thanks, Erick. It seems that you have basically said, "Yes, UDP forwarding is not part of HSRP." But you also apparently agree that there is no technical reason why this must be true :) Maybe they need to add a feature, like standby helper or something so when HSRP is being used it will only forward UDP broadcast traffic on the device that has the HSRP IP active. Example: if such a feature existed, then you wouldn't use ip-helper on HSRP interfaces - you would use standby-helper if you just wanted UDP forwarded on device with active HSRP IP address. ISTM that it would be easy to simply add a command like [no] standby-helper Everything else, including "ip-helper" is the same, and this flag simply tells a router in standby or monitor mode not to forward, but when in primary mode to do so. I guess the effort is not worth the gain. UDP's being an unreliable and connection-less transport requires the protocols to be robust enough to handle the duplicate packets. The problem arising from this duplicate forwarding with DHCP occurs when the 2nd DHCPDISCOVER is delayed enough so that the client has already received its lease and IP address in response to the 1st DHCPDISCOVER. When the server sees the 2nd DHCPDISCOVER, it will try to give the same address again. But, prior to doing so, it MAY (RFC2131) ping the address to see whether it's in use. Well, the client will respond, because it just got the IP address :) The server will then try to give another IP address and abandon the first lease. Of course, that's a contrived and highly unlikely case -- the packet would probably never be delayed that long, but it just came to my mind when thinking about this. - Tks | mailto:[EMAIL PROTECTED] BV | mailto:[EMAIL PROTECTED] Sr. Technical Consultant, SBM, A Gates/Arrow Co.

HSRP (and VRRP) share a virtual IP address among the devices participating. Hosts point their default-gateway to this Virtual IP address. This allows the hosts to still forward traffic when the primary router/switch interface goes down and the standby router/switch changes over to active. This is the function of HSRP/VRRP - to provide a shared IP address among multiple interfaces on the same network. If the interface is in standby mode for HSRP then the standby IP address isn't active on this interface, but the primary IP is active and ip-helper, routing, and all other IP features you have configured are active unless the interface is down, etc. Currently, there isn't a way to stop ip-helper from forwarding when the HSRP address is in standby mode since ip-helper isn't part of HSRP. Maybe they need to add a feature, like standby helper or something so when HSRP is being used it will only forward UDP broadcast traffic on the device that has the HSRP IP active. Example: if such a feature existed, then you wouldn't use ip-helper on HSRP interfaces - you would use standby-helper if you just wanted UDP forwarded on device with active HSRP IP address. The only way to get around forwarding UDP broadcasts from both routers would to remove the ip-helper from one of the interfaces. The problem here is when the other interface goes down you're not going to forward the UDP broadcasts anymore. The other solution would to be make the DHCP server local so ip-helper wasn't needed. If you search on cisco.com for HSRP and IP-helper you'll get a document on UDP Flooding which involves bridge-groups and using spanning-tree to block.

Both routers are configured as a DHCP and BOOTP relay agent in order to get redundancy. So all DHCP and BOOTP broadcast traffic is sent twice to the central server. Is there some reason for this to be true? It does not seem right to me. My understanding is that, normally, HSRP does not depend on multiple routers in the group to forward traffic. The HSRP group appears as one router to the side where it is being redundant, with the primary router forwarding all traffic. The standby doesn't participate, except possibly on reply traffic I think that you would agree that it is not normal nor good (maybe not necessarily bad, but certainly not good :) for a router arbitrarily to send duplicate packets onto a subnet and this is, in effect, what would be happening here. In single-group HSRP mode, I can see no reason for this to be required -- I would think that it would be sufficient for the UDP forwarding simply to

Re: Content services switch what is it ???
The CSS series switches are from the Arrowpoint acquisition. We purchased one while they were still Arrowpoint and I must say that they are *seriously* cool boxes. Basically, it is a switch that can see up into the higher layers to make switching decisions. Let's say you had three web servers that had different content but the same domain name. This switch can look inside the http request and direct it to the best server for that particular content. In our network, we use it to forward requests for cacheable content to our cache engine, and then load balance between two servers for non-cacheable unsecure content. For secure content, we have the switch configured to notice when an SSL session has been set up and it locks the user down to one server instead of continuing to load balance. That is a very cool feature, and it's especially useful if you have online shopping with shopping carts. Once someone logs in, they are stuck to the same server for the remainder of the session, so they don't run the risk of jumping to another server and losing they shopping cart information. You can also lock sessions down based on cookies if you'd like. If you don't want to use the default round-robin load balancing, you can configure it to load balance based on number of current connections, server load, etc. Once you've read through the manuals, if you need any help configuring it just let me know. I'd be glad to help you out with the details. When we got the box, I was in the same boat as you. I had NO idea what in the heck the thing did, yet I was the one tasked with learning to use it.

Re: Equal cost switching
Depending on the architecture of your network, you can balance the traffic of multiple VLANs across different links by setting the root bridge to opposite switches. So if you have an access layer switch feeding into say 2 catalyst L3 switches, you can set the root bridge for VLAN2 to the first Catalyst and for VLAN3 to the second Catalyst. This will allow you to use bandwidth from both links. This is one of the benefits of PerVLAN Spanning Tree versus a Common Spanning Tree.

Re: % Connection refused by remote host
Not knowing much about your firewall - is the async port available? i.e. - does another process have the async open? If the port is disabled or "occupied" by another program it won't be available to the terminal server. Just like the router console port. If you reverse telnet into it, then give a "ctrl-shift-6-x" to return to the terminal server, that console port is still attached to a session. If you try a second reverse telnet into the router console you will get the same error until the first sessioin is released.

Re: % Connection refused by remote host
Most likely the issue is with the config on the terminal server. Take a look at the line with "show line" and see if there is a * next to the line you have plugged into the firewall. If there is try clearing the line "clear line _" then show the line again. If this fixes it, but the issue keeps occuring you may want to add "no exec" to the line config.

If the route command statement uses the IP address from one of the PIX Firewall unit's interfaces as the gateway IP address, PIX Firewall will ARP for the destination IP address in the packet instead of ARPing for the gateway IP address. PIX Firewall also does not accept duplicate routes with different metrics for the same gateway. In version 5.1(1), the CONNECT route entry is supported. (This identifier appears when you use the show route command.) The CONNECT identifier is assigned to an interface's local network and the interface IP address, which is in the IP local subnet. PIX Firewall will use ARP for the destination address. The CONNECT identifier cannot be removed, but changes when you change the IP address on the interface. You can now enter duplicate route command statements with different gateways and metrics. You can now enter static route command statements with virtual subnets; for example: route outside 10.2.2.8 255.255.255.248 192.168.1.3 route outside 10.2.2.8 255.255.255.255 192.168.1.1 --- Jason [EMAIL PROTECTED] wrote: As someone said yesterday: The PIX will not route, period.

Citrix is faster via Internet than LAN/WAN
Hello all ! I'm hoping someone out there can help me with this. We are stumped. We are running the latest version of Citrix on an 8 server ( Proliant 6400) farm. Internally, we get to it via a couple of 2948G switches and a 3660 Core Router. But, if I go to one of our remotes sites that has a DSL connection to the Internet, they access our Citrix farm through our 2612 Internet router, then a Catalyst 2900 switch (DMZ), then through our PIX, then another 2948G, BUT they apparently bypass the 3660 and get to the farm. External access has much quicker response times than internal. The only difference I see is the 3660 router. We have 30 WAN sites and about 150 LAN hosts working through the 3660, but the CPU usage and Memory are not hurting. Could this difference just be a "traffic shaping" issue or is there something that I am just missing??? We have only a basic config on the 3660. Any assistance would be much appreciated.

Re: Equal cost switching
Thanks for all your help. The way I understand it now is that with multiple vlans using different root bridges, you can have different vlans splitting the bandwidth - some going in one direction, some in the other. But if one link goes down, STP will then shift all to the good link. This gives you some load balancing and also redundancy. It looks like you need to go to layer 3 switching to do any load balancing other than this. And etherchannel is another option for aggregating bandwidth. But someone said with etherchannel using 4 full duplex 100 mbp ports will not give 800 mbps of throughput? I always thought that in theory that was the case?? Since the data is transmitted on different wire pairs, if the sender and receiver transmit at the same time, why isn't 800 mbps possible Thanks again !!

Etherchannel decides which link to send a packet over based on a logical operation on the MAC addresses of the source and destination hosts (XOR, I believe).

to not allow a firewall to run routing protocols, could someone give me advice on how to set up my proposed redundant firewalls. Please refer to my ugly ASCII network.

On the inside of the PIXs I have one connection going to Network A and another going to Network B. But right in front of Network B (critical production network), I have a load balancing set of Checkpoint firewalls. The Checkpoints are connected to both Network A B. I want it done so that the Checkpoint will forward data to A when destined there and send all other packets to the PIX. However, if the Checkpoint's link to the PIX goes down, I want it to be able to send traffic through network A and through the PIX from there. I want it to work the other way around for the PIX going to network B. My question is, how would I do that if the firewalls don't run a routing protocol? Do the PIXs allowing for floating statics?

Re: Cisco 4000 error message..
Looks like your flash has gone bad or the image has become corrupt. Error : compressed image checksum is incorrect 0x30EAA646 Expected a checksum of 0x30EA3646 What happens when you erase the flash? An another error or does it complete apparently ok? If you "sh flash" after erasure is the file still there with a mark beside it? If the erasure apparently went ok did you "squeeze" the flash to regain the space?? This happened to me on a 3620 lately and I had to use a 3640 to erase the flash and copy a new image to the flash. Put it back into the 3620 and everything was ok. I put the flash in the second bank of the 3640 and was able to erase it (flash:2:). The episode was my fault since I downloaded an image and thought I had the whole thing and then copied it to the 3620. It happened that the download aborted and the image wasn't the correct size. The router "accepted" the tftp copy (although it wasn't complete) and both the router and the tftp server said that it copied fine. On boot I didn't get far and had to recover using the 3640. Anyway, long story - same thing. Either change the flash or maybe get another router to erase it and load it then try again.

Re: Equal cost switching
The Ethernet Bundling Controller (EBC) performs an X-OR operation on the last two bits of the source MAC address and the destination MAC address. This operation yields one of four results: (0 0), (0,1), (1 0), or (1 1). Each of these values points to a link in the Fast EtherChannel bundle. That really makes sense. I always pictured this process as the first frame in a stream being sent down the first wire, and the second frame in the stream being down the second wire, third frame being sent down the first wire.. ect.. The way you explain it makes more sense because this way the switch wont have to think about which wire it last used to send a frame, but instead it does a simple calculation. So in essence, if you had 8 wires in an EtherChannel, but most of your traffic was going only between 2 servers ( Server1 - Switch- Server2), then only 1 or 2 of the links would be used based on the X-OR calculation? So 6 of the wires in the bundle would be wasted? Is this accurate? Also, I've never really thought about it, but is it possible to have a number of wires in an EtherChannel that are not a power of 2? I.E. 3,5,6,7? It wouldn't seem possible if each wire was assigned a value ((0,0), (0,1), (1,0), (1,1)). If you had 3 wires in an EtherChannel, then the 1,1 value would not be used, and to me, I would think that the Switch would get confused if all the values didn't have an assigned value. One more thing guys! Don't let the hype about fool-duplex full you! If you have a full-duplex 100Mbps connection, you dont REALLY get 200Mbps bandwidth, you just get 100Mbps in both directions simultaneously.

FW: EMUTEL LITE setup
The spids are most likely configured in the emutel lite already since they come from the factory with a default setting depending upon which version of the emutel lite you have. The default ISDN switch is a basic-ni1 if I remember correctly. Obviously, if you got an emutel lite with a European siwtch type, then you won't have any spids to worry about. I thought it was a breeze to set up the emutel lite because there was essentially no configuration. If you don't have the manual, download it from the emutel web site to get what the default spids are. You may not need NT1s depending upon whether your 2503s have U interfaces or S/T interfaces. I am assuming you must have S/T since you are using the NT1s.

RE: Citrix is faster via Internet than LAN/WAN
It's really difficult to give you an answer without knowing more about your topology or the utilization segments as they contend for bandwidth. One thing that you should keep in mind however is that every frame destined for a PC (and every broadcast transmitted over that LAN segment) creates an interrupt that must be processed by the CPU of the end system. The load on a CPU (how much ability it has to process the network-generated interrupts) definitely has an impact on how network access can appear faster or slower. It always really boggled my mind that 20 some computers on a hub vying for a 10 Mbps uplink to the school's network terminating in a single 10 Mbps shared hub port would absolutely kick butt over computers in labs where each computer was plugged into the single "terminating" hub. You would think all the contention experienced prior to getting to that final (common-point) hub would impair access--but access was actually better. I didn't twig on the reason for that until I upgraded my home PC. With both my computers sitting side-by-side, the newer PC brought up web pages far faster than my old PC. BEST YET however, now was that my Videon cable modem service was JUST AS FAST as my dad's Shaw @ Home cable modem service. Darn I hate it when he's got better network access than I do! Something to think about--network performance isn't just something affected by bandwidth, but by a PC's capability to process interrupts. -Original Message- From: Germain, PJ [mailto:[EMAIL PROTECTED]] Sent: February 19, 2001 1:12 PM To: '[EMAIL PROTECTED]' Subject: RE: Citrix is faster via Internet than LAN/WAN They are all DPEN600s or better.

RE: Looped
Hi, My experience tells me the looped usually indicates that there is a loop somewhere. This can be a soft set loopback in either router. A loopback set at either end on the network termination equipment. The one that gets tricky is if a telco tester has left a loopback in place mid stream. Check each end to ensure that the loopback is not configured on the interface. Check you actually see the loopback from each end. I have had one end in loopback the other not. This service went to the wrong place mid stream. (the jumpers in an exchange).

Re: error on the show port counter on catalyst5505
Hi, This is the classical duplex mismatch. More than likely the PC is running at full duplex and the switch port at auto or half duplex. The switch ports says I have traffic don't send, the full duplex does not understand this concept and just keeps sending. Th packet gets interupted late and the errors occur. Hard set both the PC and the switch to maximise your traffic. Just some thoughts on the most common problem (not including 'portfast') that plagues switched networks.

Re: Citrix is faster via Internet than LAN/WAN
Hi, Check out how much bandwith each user uses, check how much memory is required. I have spent a considerable amount of time using products such as 'Ecoscope' various 'sniffers' and monitors all to check on Citrix. Over the years I keep coming to the same point. Basically as I understand Citrix (which is not very well) it takes key strokes and returns screens thereby reducing traffic. Each session however takes somewhere in the vicinity of 16K+ bandwidth sometimes very much higher. Each session takes up quite a deal of memory. Each session runs a separate service (say ftp or Xterm whatever) back to the server supplying the data. Often the slow point is from the Citrix farm back to the application. I found that to be the slow point in a number of cases. Also tuning the Citrix (turn off screen savers and the like) helped a little. Each screen saver causes more traffic, cpu utlisation etc. Just some of the stuff I found, have fun Teunis, Hobart, Tasmania Australia On Monday, February 19, 2001 at 09:46:15 AM, Germain.

RE: Citrix is faster via Internet than LAN/WAN
I would start with the basics and send a few large ping packet the servers way from various locations. If some introduce more latency than others try a tracert or two and see where the latency is. If there isnt any latency I would say you dont have a network problem unless you are doing some queuing or QoS. Probably not a good answer but an obvious start Tim -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Germain, PJ Sent: Monday, February 19, 2001 9:46 AM To: '[EMAIL PROTECTED]' Subject: Citrix is faster via Internet than LAN/WAN Hello all ! I'm hoping someone out there can help me with this. We are stumped. We are running the latest version of Citrix on an 8 server ( Proliant 6400) farm. Internally, we get to it via a couple of 2948G switches and a 3660 Core Router. But, if I go to one of our remotes sites that has a DSL connection to the Internet, they access our Citrix farm through our 2612 Internet router, then a Catalyst 2900 switch (DMZ), then through our PIX, then another 2948G, BUT they apparently bypass the 3660 and get to the farm. External access has much quicker response times than internal. The only difference I see is the 3660 router.

Re: 2 internal MSFC`s running HSRP
I can't find it right now, and in fact, it may not relate to this post, however, I have posted the rules before: Dual Sups/Dual MSFC 6500 platform Configurations MUST be exactly the same, except for IP address and a few minor items.

Re: CCIE Written Passed
Hi, Ed: Comparing with CCNP, how about CCIE written? Ed Moss wrote: I finally made a passing mark for the CCIE Written with a 79%. Four days ago I missed the passing score by only 3%. With the encouragement of several people here in GroupStudy, co-workers and friends, I was convinced to reschedule. From my original exam, I scored very low in areas that I thought I would have been comfortable in. I believe my comfort level contributed to those poor scores. Many have said it before read the question, read it again. You should know the answer before you look at the possibilities. After you have made your selection - read it again and ensure it is justified. For studying for the exam, I really don't have much more to offer than what has already been posted elsewhere on the list other than these comments: I believe the "CCIE Study Guide" by Giles provides an excellent presentation on layer one and two topics for each of the technologies (Ethernet, Token-Ring, FDDI, etc.).
