Re: question about frame
Hi, I'm not sure how to calculate it for 4 seconds, but all the documentation and examples I've seen explain Bc (Commited burst) as bc = 1/8 / line access rate, where 1/8 is the time period for a one second period which is a common time period from my understanding. Example: line access rate: 64k CIR Contracted: 32k bc (1/8 / line access rate) = 8000 be (excess burst) = 0 (recommended) According to what I read, there are 8 intervals (transmission periods) in this one second period. Interval 1: bc + be (be is only sent on 1st interval) Interval 2-8: bc only So, using a bc of 8000 and be of 0, 8000 * 8 = 64000 which is the line speed. If you make bc 4000 and be 32000 then you will be sending 32000 commited burst and 32000 excess on first interval of cycle, for total of 64000. In cisco terms (Frame Relay traffic shaping) cir = line access rate mincir = contracted CIR with provider bc = commited burst be = excess burst I hope this helps and is accurate. --- Fred Danson [EMAIL PROTECTED] wrote: Hey guys, I just got a quick question about Frame Relay. I've been reading the BCRAN book published by Sybex, and I'm finding the frame relay chapter a bit confusing. A few paragraphs from the Sybex book state the following: "Committed burst size and excess burst size are the two types of burst sizes. Each of these sizes is measured over a specific time interval called the committed rate measurement interval. Committed burst size is the maximum amount of data that the network can guarantee will be delivered during the committed time interval. The excess burst size is the amount of traffic which the user may exceed the committed burst size. For example, take a user who buys a Frame Relay circuit with the following characteristics: 1544Kbs access rate, 256K CIR, 4 second committed time interval. The user is guaranteed a CIR of 256Kbps over a four-second period. The user could transmit 256Kbps for four seconds, and the network would ensure delivery. The user could alternately send 1024Kbps for one second, representing the committed burst. However for the remaining three seconds, there would be no guarantee of delivery for the excess burst traffic." When the author says "The user could alternately send 1024Kbps for one second, representing the committed burst.", is he defining the committed burst as any speed above the CIR that does not exceed the total amount of information (256Kbps * 4 second interval = 1024K, total info) allowed to be sent during the time interval ? I always thought of the committed burst rate as a rate of information agreed upon with the Telco. For example, I thought you could get a CIR of 256Kbps and a burst up to 512Kbps, or a CIR of 256Kbps with a burst up to 1.544 Mbps. Could anyone do me the favor of defining committed burst rate and excess burst rate, and while you're at it differentiate between the two? :) Thanks, Fred Danson _ Get your FREE download of MSN Explorer at http://explorer.msn.com _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] __ Do You Yahoo!?

GSR 12008 Gigabit Ethernet line card
Hi All : Here is a scenario I have encountered. This GSR 12008 actually is served as a Internet Exchange router between A B C location. The basic requirment for this router is to run BGP4. However, this router have a 1 port Gigabit Ethernet line card connected to a 6509 8 port Gigabit Ethernet module, C also have a gigabit Ethernet port connected to this 8 port module. Everthing is fine and until recently, when the traffic of over the gigabit Ethernet go over 200MBit/s for a period, the interface will automaticaly die. (Die here means no traffic flow in and out for the Gigabit Ethernet line card of the GSR). I would like to resolve this problem. I think IOS 12.0(9)S is not some how stable but which IOS should be used? 1 Route Processor Card 2 Clock Scheduler Cards 3 Switch Fabric Cards 2 four-port OC3 POS controllers (8 POS). 1 Single Port Gigabit Ethernet/IEEE 802.3z controller (1 GigabitEthernet). 1 Ethernet/IEEE 802.3 interface(s) 1 GigabitEthernet/IEEE 802.3 interface(s) 8 Packet over SONET network interface(s) 507K bytes of non-volatile configuration memory. 20480K bytes of Flash PCMCIA card at slot 0 (Sector size 128K). 8192K bytes of Flash internal SIMM (Sector size 256K).

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.

Re: Telnet to PIX outside interface
I may your term "outside" confused here, but you cannot Telnet into a pix (outside) unless you carve a whole in the firewall (allowing your IP to Telnet through). The intended design is to pass through the firewall as VPN/ encrypted traffic, to an approved IP for Telneting or to bring up Terminal Emulation. We use either use servers or a 2500's planted inside. In some cases (real world), we use a phone activated power supplies to bring up an encryption modem. With this scenario, the connection only exists when you enter a code after so many phone rings the traffic is encrypted point to point from the PIX's AUX.

Re: Equal cost switching
Spanning Tree's job is to eliminate multiple paths to a single destination. If it finds more than one path it will put one of them into blocking mode to ensure a loop free path. Remember, Spanning Tree runs at layer two and has no concept bandwidth. If you need to setup equal cost paths to a certain destination, you will need to do it at layers above layer two. Pick up a copy of Radia Perlmans 'Interconnections' second edition. Radia is the primary authority on the Spanning Tree algorithm, she will enlighten you.

HSRP and UDP forwarding.
I was told this in another venue: It is the nature of HSRP. Both routers listen to broadcast traffic. 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 follow the primary router. Multi-group HSRP seems to present some other possibilities/problems that I haven't explored in depth yet. One point is that it would appear that having MHSRP primary routers forwarding DHCP (at least the broadcasts) would require extraordinary configuration on the DHCP server. For example, if the clients are in the same subnet, then which default gateway should it send to the client? Thus, MHSRP *with* DHCP forwarding would seem to require, practically, multiple subnets and broadcast domains -- i.e., VLANs.

I have found several different resellers but no one returns my emails so I figure they are either too busy or don't have one. If you or anyone else on this list is in still need of the 2901, I do have one for $1800.00. The 2901 switch, I understand has the same IOS as the CAT5000. Is there any other switches that also have the same IOS? yes, the 2926T, which is 24 ports instead of the cat 2901's 14 ports. The 2926T is supervisor II based, so it has FEC capibility. The 2901 is supervisor I based, so it does not. The 2901 supports ISL on all ports, the 2926T only supports ISL on its supervisor ports. Bottom line is that a 2901 is the cheapest/best way to go imho, the 2926T is going to run you more , and approach the cost of a 5002.

RE: tftp-server :mismatch not ok?(CONFIGS)
It looks like the c2500 image you have is a relocatable image, and the 4000 doesn't support relocatable images. A relocatable image is one that can be a different file # on flash. A non-relocatable image has to be file 1. The 4500 is newer then the 4000 so may support relocatable images; this may be a bootloader/bootrom version issue as well. cisco.com will have the info though. I know when you do a copy tftp on cisco, Pumpkin TFTP server reports 2-3 aborted transfers before the full tftp download. This may mean that IOS is checking the image name or just grabbing the first few bytes of the file to look at the headers, etc to see if its a valid image for that router. You can try renaming the image, etc but I'm not sure what IOS looks at exactly. --- Pierre-Alex [EMAIL PROTECTED] wrote: Ok, still does not work!

Re: Equal cost switching
Actually, the main reason to eliminate multiple paths is because of broadcast at layer 2. Lay 2 devices have to this forward broadcast, and multiple paths to a single destination will cause broadcast storm. Layer 3 devices do not have this problem only because they do not forward broadcast, they either read it or drop it. So if there is a network with no layer 2 broadcast, you do not need spanning tree at all. Of course, you can also disable it when you are sure there is no duplicated path exists. Regards, Jack ""Groupstudy"" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Spanning Tree's job is to eliminate multiple paths to a single destination. If it finds more than one path it will put one of them into blocking mode to ensure a loop free path. Remember, Spanning Tree runs at layer two and has no concept bandwidth. If you need to setup equal cost paths to a certain destination, you will need to do it at layers above layer two. Pick up a copy of Radia Perlmans 'Interconnections' second edition. Radia is the primary authority on the Spanning Tree algorithm, she will enlighten you. This is also good solid study for deeper networking knowledge. - Original Message - From: AndyD [EMAIL PROTECTED] Newsgroups: groupstudy.cisco To: [EMAIL PROTECTED] Sent: Sunday, February 18, 2001 8:58 AM Subject: Equal cost switching Spanning tree is supposed to choose the one best switched path.

Re: HSRP and UDP forwarding.
Look at this way. 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. Erick --- Bob Vance [EMAIL PROTECTED] wrote: I was told this in another venue: It is the nature of HSRP. Both routers listen to broadcast traffic. 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 follow the primary router. Multi-group HSRP seems to present some other possibilities/problems that I haven't explored in depth yet. One point is that it would appear that having MHSRP primary routers forwarding DHCP (at least the broadcasts) would require extraordinary configuration on the DHCP server. For example, if the clients are in the same subnet, then which default gateway should it send to the client? Thus, MHSRP *with* DHCP forwarding would seem to require, practically, multiple subnets and broadcast domains -- i.e., VLANs. Comments? __ Do You Yahoo!? Get personalized email addresses from Yahoo!

Re: tftp-server :mismatch not ok?(CONFIGS)
Darren- you are right... but this is not always true when dealing with 2500's. The 2500 Enterprise routers pull IOS from FLASH to RAM (same as the big Cisco's). I've only seen the "operate from FLASH" on older 2500's or lower line (cheaper) models with non-Enterprise codes. In Pierre's situation- the 4000 wanted to copy the 2500's image into it's FLASH bank, here read only is OK (to "pull or read" the image from the 2500). The running config containing TFTP-Server FLASH image name directs the image to be pulled/read whether in RAM or FLASH. The 4000 needed read/write permissions on it's FLASH, because it's the destination where the 2500 image will be stored/written...

If you do a "show version" on a Cisco2500 the flash will appear as read-only and not read/write. Therefore, you will have to boot the router into boot-mode (change the config register to 0x2101) and you will notice now that the flash is read/write.

Re: Equal cost switching
That is why I said the main reason not the only reason. Normally, before Node A sends any packet, it will do ARP, this will create loop immediately. Not so normal, you can hard coded the ARP cache. Jack ""Peter Van Oene"" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... This is actually not the case. A layer two network that contains a logical loop with get into trouble with all types of traffic flows. For example, consider a simple network like the one I'll try and draw below. Node A Node B | | -Ethernet 1--- | | Bridge A Bridge B | | --Ethernet 2-- Consider a transmission from Node A to Node B and assume that both nodes were recently powered up and that the bridge tables for the two bridges have not been built. Here is a likely scenario. The frame hits Ethernet 1 and both bridge A and B detect the packet and check their forwarding tables only to realize they do not have an entry for B. At this time they add Node A to the forwarding table as residing on Ethernet 1. They then both forward the frame onto Ethernet 2. Node B also receives the frame and processes it. However, 2 versions of the frame now exist on or headed two Ethernet 2. When the bridges forward to Ethernet 2, (1 at a time) each bridge will process the others frame and decide that A has indeed moved to Ethernet 2 and adjust their forwarding tables appropriately. Assuming B hasn't responded as yet, they will also process each others frames and still not finding B in their forwarding table, copy them back onto Ethernet 1. However, when they do, they will again switch A's address from Ethernet 2 to 1 and likely repeat the process again. Just think what happens when B responds :) All in all, this is very unhealthy. The fact that there is no way at layer 2 in ethernet to detect the age of frames severely hinders loop mitigation. In fact, there pretty much isn't any loop mitigation at layer 2 in ethernet networks. If you create a looped topology and do not prune the redundant paths, you will bring a network down in seconds.

Re: ISDN
Jim, You can schedule the exchange site connector (providing you are not using a 'Site Connector'). I would suggest X400 connector for this purpose. This will allow you to control when the exchange server communicates between sites. NT 4.0 DC relationships don't really have any way to schedule synchronisation between servers but you could always upgrade to Windows 2000 if you really needed to schedule the sync. What will be defined as 'interesting traffic' to bring up the ISDN connection? If you can control this outside the NT 4 world, then you could create an access list to block NetBIOS over TCP/IP and RPC traffic and allow the necessary traffic. X400 could be configured to send messages immediately (which would dial the connection) or as needed in the X400 connector, and you could schedule your directory connector between the two sites to only synchronise a couple of times a day, to keep the traffic on the link to a minimum. This would still allow your PDC/BDC to synchronise when the link is available, but would not dial the link or keep it active after the idle timeout. Remember that your clients need to have access to the PDC to reset their passwords and you won't be able to do any administration work on the domain from the site with the BDC, unless the line is active. It would probably be better to configure each site with a PDC in different domains and configure a two-way trust between them. Exchange will still work (I would suggest configuring with a service account local to the specific exchange server, and use the 'override' security function when connecting between sites) but you will not have problems relating to NT 4 replication. Let me know if this helps - I can provide more info if needed.

The 2611 won't do dCEF however. Also, the smaller routers can't do cef accounting. Anyway, now I have to mock something up in the lab to see if we can determine how much of any improvement CEF will give us. Since we're not using CEF anywhere in our network I can't just turn it on without a bit more research. If it only lessens the CPU load by a few percent then bigger hardware is in our future, but if we see gains of 20% or more then CEF would indeed be a cheap solution. I noticed that CEF has issues with policy routing and other features - but so far we're not using any of them.

I'm wondering if the SAR process is overwhelming the 3620? I'm sure I read someplace that only one high-speed interface was recommended for the 3620 but I haven't found that info again.

RE: tftp-server :mismatch not ok?(CONFIGS)
I sent that too soon. I meant, to eliminate TFTP'ing the image off a 2500 as a problem put the image on your PC and set it up as TFTP server. Then try TFTP'ing from your PC to the 4000. You'll probably get the relocatable image error still... I'm not sure if a newer boot prom version adds support for relocatable images or not with the 4000. A brief look on CCO didn't reveal anything. If a image on the 2500 is running from flash - the flash is read-only. Try TFTP'ing the image from the 2500 with your PC to see if it sends it to you. I don't have a 2500 handy to try. This isn't going to solve your problem but would be interesting to see result. Erick --- "Erick B."

If you do a "show version" on a Cisco2500 the flash will appear as read-only and not read/write. Therefore, you will have to boot the router into boot-mode (change the config register to 0x2101) and you will notice now that the flash is read/write. You will now be able to TFTP the image to flash. I hope this helps, and if you have any problems let me know.

A relocatable image is one that can be a different file # on flash. A non-relocatable image has to be file 1. The 4500 is newer then the 4000 so may support relocatable images; this may be a bootloader/bootrom version issue as well. cisco.com will have the info though. I know when you do a copy tftp on cisco, Pumpkin TFTP server reports 2-3 aborted transfers before the full tftp download. This may mean that IOS is checking the image name or just grabbing the first few bytes of the file to look at the headers, etc to see if its a valid image for that router. You can try renaming the image, etc but I'm not sure what IOS looks at exactly. --- Pierre-Alex [EMAIL PROTECTED] wrote: Ok, still does not work!
