BRI ISDN layer2 going to sleep
Hi all, Has anybody experienced an ISDN BRI "going to sleep". After periods of inactivity, the layer 2 status is not shown as active and incoming calls cannot be received. Shut then no shut on interface does the trick. I suspect this could be some configuration on BT equipment, but is there any workaround, or is there some form of keepalive which is not default. Switch is basic-net3. Config is a real basic one used successfully in many other locations.

Re: What can CDP offer ?
Hi Adia, I have found that CDP allows a bundle of good things. Below are some examples, A couple of switches on different LAN's the client tells me are configured correctly on each LAN with the correct SNMP community name cannot be discovered using SNMP and he cannot Telnet to them. I am the supplier of the routers. I perform a "sh cdp nei det" and in an instant can tell my client what he has done is configured the switches on a bench in his office. Put them into the car and delivered each switch to the wrong building and therefore the switches are configured for a different LAN. On an FDDI link a major client can see the services on the ring but cannot get data from point A to B. A quick glipmse "sh cdp nei det" once again reveals the two routers in question have an IP address mixup. In this case both the same IP address. Looking through the ARP table would confirm this but the there were several hundred entries there. I wanted to know if I had exactly matched my drawing for a switched network having some 50 2900XL switches going into a 5500. I also needed to document serial no.s etc. "sh cdp nei" gave me where the switches were. It was a simple matter antering the data into the 5500 so this was in a sense self documenting. A cut and paste of the details gave me the resto of my doco. When IP, AppleTalk and/or IPX fails CDP might still be there and show config issues. CDP is very handy.

Re: Clock Rate Wire Rate Bandwidth
Used in the context of data transfer, wire-speed means the maximum rate at the physical medium can accomplish the data transfer. What determines this is mainly the physical medium's capabilities (bps rate or number of bits per second) and minimum packet size. Wire-speed processing means that the interface can process each packet at the maximum packet arrival rate. Maximum transer rate is not always available depending on the design of the connector, the physical condition of the connector (dirty, cross-threaded), the interface software driver's capability or configuration, how busy the router's CPU is, etc. I'm probably leaving out something but you get the idea. Be careful about the use of the term "bandwidth" when talking about Cisco routers. The IOS keyword "bandwidth" is used to inform routing protocols (and other processes) about the effective speed of an interface (physical or logical) and may not reflect actual line speed. In phyics, bandwidth is defined as the range of frequencies that a signal occupies on the media. In networking Andy is correct - it usually refers to how fast data is flowing which is pretty close to wire speed if you ignore overhead bits (sync and so forth).

Re: Serial port with identity crisis
Hi Tim, This is typical behavior when using Frame Relay in a main serial interface. This is because unless you are using a point a point sub interface the router relys on map statements or classes to map layer 3 ip addresses to layer 2 DLCIs in the frame cloud -- even though you have given the interface its ip with 'ip address'. You can get around it at follows : Scenario 1: interface serial 0 ip address 10.1.1.1 255.255.255.0 encap frame frame map ip 10.1.1.1 100 <-- Will allow you to ping yourself frame map ip 10.1.1.2 100 <-- Will allow you to ping your neighbor or interface serial 0 no ip address encap frame ! int ser 0.1 point-to-point ip address 10.1.1.1 255.255.255.252 <-- Hey its point to point, save yerself some IP addresses frame interface-dlci 100 Cheers jim.

Re: Clock Rate Wire Rate Bandwidth
I don't know if this made it earlier but here it goes again. Sorry if I repeat myself. Hi, I'm an old guy. It has always been my understanding that something needs to control that is synchronise the signals across a given link. This needs to be controlled from one end only as if there was a slight variation in the clock speed of one device to the other you would get a signal drift and the bits would not coincide. In a simplistic sense where the clock pulse both hits together all is fine when they miss hit we are in no mans lands. In order to acheive this most old systems used a master - slave relationship ie. The master provides the clocking and sends it as a constant pulse to the remote end. Both ends then use this to time the bit pulses. The idea here is to measure a bit somewhere in the middle of its peek signal period. OK I know is is a bit and therefore the signal is a square pulse but due to attenuation in the cable (Capacitance, resistance, refection etc.) it is no longer square when the remote end sees it. If the clockrate is not set correctly to the bit rate sent on the wire we get a drift of the signal and a failure may occur. Cisco use the DCE end to set the clock rate. Setting it to the appropriate speed the remote en knows what to do with it. Most Telco's and or Modem type equipment supply the clocking and the router becomes a DTE device. This provides the time. The "bandwith" statement in the router has no effect on the data rate going out of an interface. It is used for metrics and various management tasks and is totally indepentant of the clock speed on a port. For example in Australia we often get routers where the bri ports show 56K and the serial ports by default are the 1544 or whatever some use. The ports work just dandy to our 2048 and 64K services but if we do not change the bandwith statements we can get 115% or more utilisation an a link. (This is a huge cost saver ;) ) The 115% often creates heated discussion with clients as they get bill for using links over the capacity the see. This is not true only the graphs are out. I'm sorry for being long winded but this topic comes up a lot with various people I deal with. This is a simplistic view and not meant to be totally accurate but give the general gihst.

Re: BRI ISDN layer2 going to sleep
Hi, This is anotherone that comes up a lot with people that use a service from the outside but not always from within. If you don't have the dialer-list (x) protocol [ip ipx or whatever] permit [access-list if wanted] set your dialer won't dial. If this is set but your traffic is always generated from outside the network then run a bogus rip process. This will send out the odd packet and keep your link up. Only do this if you want to tie up the link.

Nagle's algorithm
Does setting 'service nagle' on a router have any effect on TCP sessions transitting the router, or does it only have an effect on sessions that terminate at the router? Various bits on CCO vaguely imply that it affects through traffic, but having read up on how Nagle's algorithm works, I can't see how it could - as it works at the TCP layer, I think it should only affect sessions where the router is a session endpoint. Can anyone confirm this, or am I missing something?

You can if you do a little coorelating. Note the MAC address in the CAM table for the port. Telnet to the router that serves the VLAN and query the ARP table.

Re: Re : ISDN Backup
You don't need to use the backup delay command if you're using floating static routes for backup, in fact I'm not sure that it will actually do anything (how does it know what the secondary interface is without a backup interface command?), but I've never actually tried using it with floating statics. Using floating statics, how quickly the backup line kicks in should depend on the convergence time of your routing protocol and design. EIGRP should be pretty quick, generally. What puzzles me, though, is the statement 'isdn backup is not able to activate (momentarily activates and then disconnects)'. Do you mean that the ISDN call doesn't work, or that the call is disconnecting before the idle timer expires or what? Generally (depending on bits of the config that you haven't shown), if the serial link goes down for long enough for the routing table to point to the ISDN instead, the ISDN will call and will stay up for at least 120 seconds (default idle time), even if the routing quickly reconverges back to the serial. If the serial link goes down (or has errors) for such a short period that the routing table does not point to the ISDN, then the ISDN won't call at all. Does it work OK when the serial link goes down and stays down? If so, how quickly does the ISDN activate? If the serial link is flapping, is the ISDN call (including PPP negotiation if you're using PPP) successful? debug isdn q931 and debug ppp neg or debug ppp auth may show any connection problems, and debug dialer may show why it is disconnecting.

Re: BRI ISDN layer2 going to sleep

Re: can I tell the ip of the PC that connected to a switch port?
Then that wouldn't be telling what the IP of the PC that is connected to which port. You might even say just follow the wire that connects from the PC to the port and lookup the IP of PC using network neighborhood. What I'm trying to answer is in the basic function of a switch, there is not way you can tell what the ip of the pc connected to a port is.

Cisco sales engineer -- ARGH!
Is it just me or is it that Sales engineers at Cisco try to sell stuff that they don't even know will fit right for the environment at which the Cisco stuff are to be installed. Take for instance, I invited a Sales engineer to come over our office this morning showing him what our network looks like. We have about 170 users connected to HP 4000 Switches. Anyway, this guy walks in, tells me that "oh, this is not the best solution. The best solution is to go with a pair of 6500 Catalyst switches for redundancy with an intergrated router and VLANs blah blah blah". It seems like he just got off a class about 6500 and he was inspired to sell it to us using every acronymn he heard at the training class. $12000 MSRP for a 48 port 10/100 is not exactly a selling point when it comes to comparing prices with either HP or Foundry. This guy doesn't even know that 6500s aren't normally implemented in the Access Layer unless we have some spare $100,000 to throw around! Just because they work for Cisco doesn't mean they're network engineers! Whew,... that felt good. I needed to vent a little. Now, I look forward to Monday when I'm supposed to meet with a CCIE who works for Foundry...

Hi Eric, I'd take a different angle to Brian, I did my CCNP v1, CCDP and then MCNS & CATM before my drake test. I had my CVoice booked but time kindof got the better of me. (That and the new CVoice2 Exam) As a refresher I also covered the Routing 2 & Switching 2 Course Notes/Exams as this gave me a more confidence and exposure to BGP, Multicasting, MLS etc.. I believe it all helped, yet when I look back probably 60-70% my Drake (CCIE Written) I answered from experience not the few days worth of study I did before hand.

Re: can I tell the ip of the PC that connected to a switch port?
Hi, Do a show cam dynamic on the switch port. This will give you the MAC address. Go to the router or whatever do a show ARP and it will give you the IP address tied to the MAC address. An ARP Table as I understanmd it shows the mapping of IP address to MAC addresses. The CAM table shows the table of MAC addresses to ports Teunis Hobart, Tasmania Australia On Thursday, December 14, 2000 at 11:05:34 PM, Kenneth Lorenzo wrote: > Then that wouldn't be telling what the IP of the PC that is connected to > which port.

Re : ISDN Backup
Hi jenny, Yes, I agree that with floating static routes backup delay command would not work. When my serial link is completely down then the ISDN backup works perfectly well. It is only when the serial link is flapping that the real problem comes up as neither the condition of the link is good enough to handle the load nor does it allow ISDN to takeover. In such situations how can I prevent downtime by allowing the ISDN to take the load. Secondly I wanted to increase the ISDN bandwidth by adding more ISDN lines.( The present bw is 128kbps (multilink enabled) Any hints/suggestions on that would also be appreciated. Thanks & Regards Amit You don't need to use the backup delay command if you're using floating static routes for backup, in fact I'm not sure that it will actually do anything (how does it know what the secondary interface is without a backup interface command?), but I've never actually tried using it with floating statics. Using floating statics, how quickly the backup line kicks in should depend on the convergence time of your routing protocol and design. EIGRP should be pretty quick, generally. What puzzles me, though, is the statement 'isdn backup is not able to activate (momentarily activates and then disconnects)'. Do you mean that the ISDN call doesn't work, or that the call is disconnecting before the idle timer expires or what? Generally (depending on bits of the config that you haven't shown), if the serial link goes down for long enough for the routing table to point to the ISDN instead, the ISDN will call and will stay up for at least 120 seconds (default idle time), even if the routing quickly reconverges back to the serial. If the serial link goes down (or has errors) for such a short period that the routing table does not point to the ISDN, then the ISDN won't call at all. Does it work OK when the serial link goes down and stays down? If so, how quickly does the ISDN activate? If the serial link is flapping, is the ISDN call (including PPP negotiation if you're using PPP) successful? debug isdn q931 and debug ppp neg or debug ppp auth may show any connection problems, and debug dialer may show why it is disconnecting.

RE: Why so many buffers ?
Yes, you can adjust how many buffers of each size the router maintains. Buffer tuning is somewhat risky, though. You might want to talk to TAC first. By the way, in my previous message, I prefaced my comments with, "If you can believe the CIT class." I'm not sure you can believe that class. &;-) For more info on buffers, see the following Web page written by TAC. It might be more reliable. http://www.cisco.com/warp/public/63/buffertuning.html Priscilla P.S. Please send messages to the group. I can't always answer questions sent to my individual address.

RE: Cisco sales engineer -- ARGH!
Kenneth, I have been in your shoes. You need to voice this to your sales team. Unfortunately there are people out there who don't have your intelligence and would have been in AWE by his/her recommendation. I am not referencing this to Cisco, but to the situation in general. I am not speaking negatively of your SE, Sales Team, or Cisco either. Keep in mind that a sales team is a tool that you should use to your benefit. If a SE has his head in the clouds, make sure to let him know you are still on the ground, for whatever product he is trying to sell you, for whatever vendor he works for. This will help ensure a productive relationship for both parties. -Eddie P.S. If you have 170 users, you should think about purchasing a 12016 GSR for each of them...

The best solution is to go with a pair of 6500 Catalyst switches for redundancy with an intergrated router and VLANs blah blah blah". It seems like he just got off a class about 6500 and he was inspired to sell it to us using every acronymn he heard at the training class. $12000 MSRP for a 48 port 10/100 is not exactly a selling point when it comes to comparing prices with either HP or Foundry. This guy doesn't even know that 6500s aren't normally implemented in the Access Layer unless we have some spare $100,000 to throw around!

Hssi simplex configuration
I have a new customer that will be connecting to a Cisco 3600 with two Hssi cards. They will be connecting to us via a satellite modem. This will be a simplex circuit (customer receive only). The other Hssi port will be connected to a Frame switch (direct connect to UUnet). Encap is hdlc on the customers end. The frame switch and the satellite modem will provide clock.

RE: Nagle's algorithm
Jen, I see your point. I just finished a quick read of RFC 896 (Congestion Control in IP/TCP Internetworks) Recognizing that TCP is responsible for end to end reliable data communications, it would seem reasonable to think that the Nagle service should not effect transit traffic. On the other hand, the RFC does mention issues on slow links, and does mention gateways ( routers ) in a couple of places in a way that imply that the edge router is the place where the mechanism is best put to use. The Cisco references I browsed appear to quote verbatim from the RFC, talking about the single character of data in a TCP packet, and the overhead involved. The further description of the service Nagle implies ( but does not state - in my reading, anyway ) that a router running service Nagle acts as a host proxy, almost in a stateful manner, examining the behaviour of the traffic, and acting accordingly. I'm too sleepy to attempt to get through RFC 2001 this evening. The intro to that one talks about modern TCP implementations, saying to me, anyway, that maybe congestion control mechanisms such as Nagle are now built into end station stacks. What were your thoughts from your reading?

They also don't get a lot of hands on time because they are not expected to. This is a job for our partners or our own Professional Service team. No matter what you ALWAYS want more than one opinion in anything you purchase or implement. Everyone has a different way to do things, and this is where this mailing list provides a lot of value. -Eddie -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Jim Bond Sent: Friday, December 15, 2000 1:47 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: Cisco sales engineer -- ARGH! 1. I think you should talk to a Systems Engineer, not Sales Engineer. 2. 6500 switch doesn't fit in your network doesn't mean Foundry is better; likewise this sale guy is idiot doesn't mean all sales guys at Cisco are idiots. I say this because I'm very happy with Cisco SEs. I've worked with at least 15 of Cisco SEs, most of them are kind, helpful and knowledgeable. Just my opion.

Re: EIGRP
Go to the CCO & check known bugs. I found 11.2(14) in an EIGRP router, that only caused a memory leak with EIGRP turned on. CCO had it, I swapped 2 routers before I began to turn my attention away from faulty FLASH. Phil PS- I do not think default IP Classless & IP Subnet Zero came in until 11.3, so you always need to watch for that when configing this old stuff. - Original Message - From: "Kevin Wigle" <[EMAIL PROTECTED]> To: "John Neiberger" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Wednesday, December 13, 2000 5:23 AM Subject: Re: EIGRP > however, as has been suggested by Louie Belt and my example shown here: > > http://www.cisco.com/warp/public/103/eigrp4.html > > it seems that the network statement has been changed in the latest > releases.. > > Kevin Wigle > > - Original Message - > From: "John Neiberger" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Tuesday, 12 December, 2000 18:13 > Subject: Re: EIGRP > > > > The 'network' statement in EIGRP is classful and accepts only the network > > number with no mask.
