RE: ATM PVCs Switching on Router 7200 [7:74094]
Hi Mohammad, You can not really switch an ATM PVC on a router, you need to have a switch (popularly called WAN Switch) for that. But even then, if you have 2 ATM PVCs facing different sides, you can exchange traffic between them, by IP routing. e.g. you have one PVC configured on interface atm 1/0 with IP 10.10.1.1/30 and another interface atm 1/1 with IP 10.10.2.1/30. Now both these interfaces will be talking to their respective counterparts on the other side, but on the router you can simply configure adequate IP routing and the router will get ATM cells from atm 1/0, convert them to IP packets, hand them to in IP shape to atm 1/1, which will again convert the IP packets to ATM cells and those cells will be sent out to remote location. Please revert in case more information is required.

Is it through a path that actually handles a 3000-byte packet without IP fragmentation? ATM might default to a high MTU, but if you're starting on Ethernet, then you can't use such a large MTU. So that means that you're doing IP fragmentation. That takes time and causes even more overhead from headers. UDP has an 8-byte header. IP has a 20 byte header. Ethernet supports an MTU of 1500 bytes. So, first figure out what your tool means by 3000-byte packet. Does it count headers? But probaby you want to test with 1472 at most, assuming you're starting on an Ethernet link. If you're starting on ATM, find out the MTU for the ATM interface. So, add to my list of things that affect throughput (not bandwidth): IP fragmentation and reassembly.

Yesterday, we did stress > test in the link and just only reach 30Mbps. Bandwidth means capacity. It is a given. The amount of bandwidth you have is dictated by your provider and the type of interface you are using. It is not measured. It doesn't change (unless you have some technology that uses dynamic bandwidth allocation, such as multilink PPP). What you seem to be doing is measuring throughput. Throughput is measured. It's the amount of data per timeframe that can be sent. Because they have the same unit of measurement (bits per second or something similiar) people think bandwidth and throughput mean the same thing. They don't. Just want to encourage people to use the terms correctly! :-) Now, throughput can measure numerous different things. If you had a tool that could send raw, unframed bits as fast as the interface allows, throughput could equal bandwidth, assuming the link is not used by anything but your testing tool. Since such tools aren't very common, and, of more importance, don't resemble real-world applications, that's not how throughput is really measured. What you really care about is the user's experience. So you care about application-layer throughput. Some tools let you measure the amount of user data that is sent per unit of time. This refers to the application-layer payload. It leaves out overhead caused by headers at the data-link, network, transport, and application layer. Or you can measure throughput using a tool that does count data-link layer overhead, or network, or whatever. If you don't know what your tool is measuring, find out. Otherwise your results are meaningless. Throughput, depending on what layer you are measuring, can be affected by numerous factors: * packet header overhead (and ATM cell overhead) * errors, resulting in retransmissions and dropped frames * dropped frames at internetworking devices due to buffer overflows * media contention on shared links * protocol behavior, including the need to find a resource, set up a connection, ack data, etc. * RAM access speed at end systems and internetworking devices * hard drive access speed at end systems * processing required at end systems and internetworking devices * software inefficiencies And about a zillion other things, depending on what you are actually measuring, which is not bandwidht, but is throughput at some layer. :-) ___ Priscilla Oppenheimer www.priscilla.com > > I thanks any comment. > > > - > Yahoo!

RE: ATM Bandwith [7:71937]
Hi Gerard, ATM as a technology per se, is a high overhead technology. As the basic fact the fixed size cell is of 53 bytes and out of it the Cell Header consumes 5 bytes. So the net payload per cell is actually 48 bytes only, so effectively you are having a close to 10% overhead, and it is not the end, you have to leave some bandwidth on the error detection etc things also, because of which you are never able to use more than a tentative 90% bandwidth on any kind of technology. So if you are getting a burst of 30 Mbps on a E3 link, (I would like to know about the bandwidth consumption tool or parameters used by you) you are not doing bad; for sure.

This is very useful, even mandatory, when doing certain backup configs and HSRP tracking. Without OAM your subinterface is up regardless of the state of the connection on the other side of the PVC. The physical interface is indicative of the status of you connection to the ATM switch. OAM allows for the status of the PVC.

Ensure your routers are configured with this setup as well. The problem is the config you have currently setups end to end pvcs as 48 to 49 and 49 to 49 but what you need is 48 to 49 and 49 to 48.

RE: ATM for Practice Lab [7:65087]
Hi, Just yesterday I was wondering the same thing. I checked into getting ATM for my home lab and the cheapest I came up with was $1,500.00 for all needed equipment. Check Horizondatacom.com - Cisco Lightstream 100 - $495.00 They have 2 available. Check Ebay - 2 4500M (165.00 each). One seller has six of these for sale. No modules, however 16/16 with 12.0 IOS. Do the following search from the Ebay main page - cisco 4500m. This auction will end in 19 hours from now (time now is 3:30 pm EST) Check Ebay - 1 seller has a np-1a-sm for an unbelievable $200.00 and another seller has a np-1a-sm for $425.00. Do the following search from the Ebay main page - cisco np-1a-sm. The first guy's auction ends 3/13. It depends on how your finances are. I mulled over whether to buy but decided to use an online rack rental for ATM. Best of luck.

RE: ATM explanation [7:62502]
Silvia, We can better help you if you could share the ATM interface and sub-interfaces' configuration lines. Feel free to sanitize them first before sharing though. It is common practice that when you use sub-interfaces on a router ATM port, you apply global Interface settings to the physical interface, but not IP addresses or vpi/vci settings for instance. So, I would think that the physical interface on your router does not have an IP assigned to it. Thus, you can't ping it. You should be able to ping the other sub-interfaces, provided that they have an IP address, form part of the routing table and there are no ACLs that prevent your host from getting the echo replies.

After discovering the vpi/vci using atm ilmi-pvc-discovery, how do you determine the ip address of the next hop router using ATM-INARP? I have already used show atm map to check if inarp has not dynamically mapped an ip but it deos not show any results Even if I configure the discovered vpi/vci statically pvc madisa 15/50 the inarp is not working. Is there anything that i must configure extra to get inarp mapping from the switch Thanx Madisa Subject: ATM PVC discovery * From: "Andrew Bratchell * Date: Fri, 1 Nov 2002 14:30:35 - * Content-class: urn:content-classes:message * Thread-index: AcKBtE1VndbwNHJFR6mCs1aRQ6g0uQ== * Thread-topic: ATM PVC discovery Angelo, 1) You must discover the VPI/VCI pair that has been assigned to you (what is configured on the ATM switch) using the commands :- atm ilmi-pvc-discovery pvc 0/16 ilmi You have done this already. Next to see what the VPI/VCI pair is, execute the show atm pvc command. If you have a pair like 5/53 for example in which 5 is the VPI and 53 is the VCI, then create your PVC accordingly interface ATM1/0 ip address 1.1.1.1 255.255.255.0 atm ilmi-keepalive pvc CCIE 5/53 protocol ip 1.1.1.2 broadcast ! NOTE you can remove the pvc 0/16 ilmi and pvc-discovery statements. If routing protocol traffic is passing through the PVC, then you need to make sure that the broadcast keyword is applied. In my example we are saying to reach ip address 1.1.1.2 go through PVC CCIE which has a VPI of 5 and VCI of 53. This example shows the new way of creating a PVC (post 11.3) rather than using map-lists which was the old way. If you are creating traffic classes etc for ATM then you need to do it using the new way rather than map lists. There are some good TAC docs that explain the differences. Finally so you can see what the config would be like using map-lists :- interface ATM1/0 ip address 1.1.1.1 255.255.255.0 atm pvc 1 5 53 aal5snap map-group CCIE ! map-list CCIE ip 1.1.1.2 atm-vc 1 broadcast Notice that when using map-lists we specify the command atm pvc NOT pvc. Also the number 1 refers to the VCD which you also have to define. This VCD value matches with our map-list statement (atm-vc-1) Hope this helps.

Yes indeed, you simply configure the frame and ATM as you normally would, and the provider will provide which vpi/vci maps to which DLCI.

Eric, Thank you for your response. It was a typo on my part entering the information in the posting. The map-list in the router does have the correct IP address. I have defined (many times) the additional PVC's on the "NEW SITE" router/map list without any success. I apologize, I should have stated that in my previous posting. I inserted the neighbor statements in the OSPF process, but no success. THE SHOw IP OSPF Neighbor statement shows ATTMPT/DROTHER for site "c" but eventually shows as being down. Also, I receive a message on the "new site" router " sent youngest key0".. Thank You for your assistance.. -Original Message- From: Erick B.

Re: ATM Problem [7:55238]
Hi, The New site has 2 ATM PVCs defined, with a ip entry mapped to site A and C. Site C has a typo under it's map-list for the new site, going to 192.58.135.68 instead of 192.68.135.68. New site has no PVCs for site B yet configured. Also, this is multipoint non-broadcast interface so under OSPF you will neighbor statements.

No, OAM does not have a corresponding mechanism in frame relay and does not help in internetworking as far a interface up/down status.

Thanks all..I thought there was a way as it's simular to Frame in nature Now, if I have 2 modular 2600 routers does anyone know if Cisco sells ATM Cards for this device so that I can emulate ATM lines and if it's anything like Frame Relay there should be a clocking on end is this correct?

Re: ATM Network Simulation [7:51319]
one smart alecky answer is yes - frame relay. Caslow calls frame relay the basis of understanding of x.25, ATM, and SMDS. Not that x.25 or SMDS are relevant any more. Although there are any number of particulars that are different, ATM fundamentals are exactly the same as frame relay fundamentals. I.e NMBA, pvc mapping, point to point subinterfaces, point to multipoint subinterfaces, either of the above to a physical interface. if you don't have equipment and want to study configuration particulars, perhaps you might consider rack rental at one of the various places. several of them have ATM switches, and you can get into more of the ATM specifics if that is your goal. -- coming soon: www.chuckslongroad.info "" 416South"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > looking to know if there is a way to simulate an ATM network > > Thanks Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=51474&t=51319 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: Anybody seen this error before re: ATM? [7:49614]
Okay, I was able to make my ATM configuration work, but I had to map IDENTICAL vpi/vci numbers on each router end. For example, on the L1010, from interface atm12/0/0, I had to input "atm pvc 5 200 int a12/0/2 5 200". Then on the routers, I had to configure the same pvc numbers. This way, I was able to ping each end. Now, I'm wondering why I had to do this. Can't I configure a different vci value? My stick network drawing is as follows: R1atmL1010atmR2 Again, I was able to make it work, but I'm wondering why I can't vary the vci values on each router. Anyone have any ideas?

Re: ATM IMA interface problems [7:47849]
whoa, now, hold on there! IMA is an open standard. IMA equipment is manufactured by Adtran, Kentrox ( or whomever they are these days ) Nortel, Newbridge, and yes Cisco. Just to name a few that come to mind. Out here in Pacific Bell land a couple of years ago there were severe ATM IMA issues which eventually were traced to bugs in the Newbridge switch software that was in most of the telco CO's. I believe there are still a few known issues with IMA, centering around how lines are terminated on both side of the circuit, not just the CPE side. Sometimes it takes a bit more time on the horn with the switch tech to work through these issues. But for the most part, over the last year or so, I have sold a number of Cisco ATM IMA solutions, and they have performed flawlessly. I have not experienced the issues you mention. Which leads me to believe that maybe you had configuration issues, or maybe your telco had configuration issues. Or both. In my experience, you are quite likely to run into switch techs who don't understand IMA, and therefore are not adept at configuring their side correctly nor in working with customers to resolve issues. My 3 cents or so.

Re: ATM IMA interface problems [7:47849]
This is going to be of no help to you but when we used these cards to bundle multiple T1's we had nothing good to say about the way it worked. There were multiple issues, i.e looping one T1 would cause the whole bundle to go down. Clearing groups like removing one T1 from the bundle was causing problems as well.

Re: ATM IMA interface problems [7:47849]
did you remember to do a shut/no shut on the physical ATM interface after you made the change? also, idle curiousity - how many T1's are you inverse multiplexing? Was the circuit ever working? I ask because sometimes when you have a single ATM T1, the telcos do not terminate it to an IMA port, and IMA will not work.

RE: ATM IMA interface problems [7:47849]
The VBR-NRT parameters musr matche the ATM Carrier Switch settings. So If the Carrier ATM Switch is set for UBR then You can't just change your ATM interface parmaeters from UBR to VBR/NRT. You have to match the Carrier ATM Switch settings only. Also try: sh atm vc to see the VPI/VCI values of peak Mbps, Ave Mbps and Min Burst Cell size, these also Must mtach the ATM Switch on carrier side.

RE: ATM question [7:44498]
David, You are correct in your second statement regarding dynamic bandwidth allocation, if you only have one pvc it will be allocated full line rate. If you have ten pvc's configured, one pvc may be using 100Mbps and the others will be sharing the remaining bandwidth depending on traffic loads. Hope this helps. -Dave Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=44512&t=44498 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: ATM and Voice [7:39849]
first off, I can't resist being a smart ass, as most list members who've been around more than a couple of weeks will tell you. secondly, with regards to the Lab topology, the Soltie book doesn't even come close, based upon my last visit. that is not to say that Soltie is not worth studying. He covers the issues quite well indeed. My point is that if you focus on issues, as demonstrated in a number of study materials such as Soltie, Caslow, BootCamp, IPExpert, and others, you will acquire the skills that are necessary to pass. the core topics are no secret - and the biggest and most important thing one can spend time on is redistribution between any two routing protocols over any network topology or link. The success of accomplishing this, or the lack thereof effects reachability, and if you don't have reachability, none of the other stuff will work, be that voice, dlsw, ipx, or anything else they throw at you. with regards to your subsequent question, I'm in pre-sales myself, and I often use my home lab to mock up customer networks and test concepts for designs I am proposing. I don't have ATM, but I like your idea. I have not priced this out, but I would thing that T1 ATM would be sufficient. If you can do ILMI and various kinds of QoS that would be great. Sure wish I had the capability. Having the LS1010, if you had edge equipment such as 3810's or 2650's with the ATM module, so that you could emulate a cloud, I can see the practical advantage, not to mention the advantage for study.

RE: ATM CBR [7:39423]
Georg - I have been told by the provider that all of their switches are currently set to UBR, which leads me to believe that only the physical limitations (T1 circuit) are governing how much bandwidth I am allowed, but I guess what I'm really needing to know is that if I split the T1 circuit into 2 PVC's (this is already done on the switches) and then make these configuration changes on each end of the cloud (at each CPE device) will that effectively limit the PVC's respectively - say 768k and 768k and guarantee that amount of bandwidth to each PVC? And moreover, is there a way to configure it so that say PVC 0/35 has minimum of 768K but can cut into the bandwidth available for say PVC 0/36 but not vice versa Kevin Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=39486&t=39423 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: ATM CBR [7:39423]
Hi Kevin, to my best knowledge, the provider of the ATM cloud needs to cooperate and configure the ATM switches accordingly. Otherwise, it would be up to the end user to determine the CBR, and the service provider would have no control over it, and hence no way to determine what capacity is available on his network. Hope this helps.

Also depends on what you are preparing for. If you are prepping for the C&S, you will need an LS1010. It supports cell mode MPLS with P functionality. Also supports VPNs and TE.

RE: ATM for CCIE [7:38772]
Older boxes such as the 4500/4700 and 7000 support ATM interfaces. When I was paying attention, it seemed that they were more readily available for the 7000s. Downside to the 7000s is that they max out at 11.2? code unless one buys a RSP7000 card set. LS100s are cheaper than LS1010s. I have seen quite a range of prices for LS100s from over $3k to $1k. I bought one with three OC-3 MM interfaces for $1,500. It is for sale as I built a LS1010 from parts. (i.e. Bought a chassis, then bought card(s), Then bought ASP.) Let's just say that you can buy a heck of a lot of rack time for the same money. > -Original Message- > From: Tom Scott [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, March 19, 2002 9:48 AM > To: [EMAIL PROTECTED] > Subject: Re: ATM for CCIE [7:38772] > > > The one book I'm reading is from ciscopress: Cisco ATM > Solutions, by Galina Pildush > > The next question is, How does a cash-challenged individual > such as myself set up an ATM lab in his basement?

Re: ATM route check [7:38201]
Hi, lane uses svc's to build data-direct connections between LECs, so in principle you can trace the path through all intermediate atm switches by simply doing show atm vc and writing down all the cross-connects on the NNI switches. Needless to say, this may take quite a while... Another method is to simulate (compute) a path by using pnni command: "show atm pnni dtl node " executed on the atm switch.

The argument is that there's less configuration to do if you use dynamic SVC setup than PVCs. Of course, this isn't a big issue in a small network.

T1 ATM would usually terminate on ATM IMA equipment. this can be a router blade, or an external box from someplace like Adtran of Kentrox ( yes I know they changed their name ) up to 45 mbs would probably come in on a DS3 electrical ( coax ) but more likely the telco would hand off fiber.

Re: ATM issue [7:33802]
The primary reason I have used OAM is when a customer has a backup circuit and lets say you use a floating static route. If the remote sight has a problem your ATM interface will stay up thereby negating the usefulness of the floating static route. In ATM as in frame, up an up is only to the repective switch, not the remote device. With OAM enabled the end devices, i.e. routers, communicate with each other as to their status. If they loose a configurable number of OAM cells the interface will declare itself down. This is also nice for customers that are monitoring their ATM network via SNMP. I'm not quite sure what your concern is when you say it may complicate things, it just allows for the real status of the link to be known. Hope that helps some Dave Chuck Larrieu wrote: > > I'm asking because I don't know the real world answer, and don't have a lot > of real world experience with ATM. > > My reading is that OAM will shut down interfaces when the end to end ATM PVC > fails.

Re: ATM issue [7:33802]
This is definitely something that we have a need for here. We have multiple locations with DSL backup links that terminate back here on an ATM DS1. Since these are backup links, without OAM I have no way of knowing when there is a problem with one. Qwest DSL support certainly isn't going to call me and let me know! So, I've enabled OAM and now get a nice syslog message when the link goes down. This allows me to get a quicker start on my one-hour phone call with clueless tech support. ;-) John >>> "Chuck Larrieu" 1/31/02 8:55:17 AM >>> I'm asking because I don't know the real world answer, and don't have a lot of real world experience with ATM.
