ATM PVC VBR
Dear all, I would like to know is it any difference between two method of configuring PVC 1. atm pvc 32 1 32 aal5snap 32000 32000 2. pvc 1/32 . . I am using method one, I have a problem is that I built a PVC between two routers (12008 and 7507) running BGP, in-between is carrier network. And the setting of carrier is VBR, I have set PVC on both routers as VBR. Once I have booted up 7507, the speed is fast and normal, but after several minutes, the speed is very slow. However, if I configure CBR - within the range of VBR's SCR, the speed is normal and fast. Is it any parameters I need to concern when I configure VBR?

RE: 2600 router - critical situation
This happened to me last week. It turned out to be a problem with the router resources. When you downloaded the IOS image it should have informed you what the minimum Hardware required to run the image is (Flash and RAM, 2600 default 8/32). After upgrading the flash, there is not an IOS image, so tftpdnld, as recommended by others, is your friend. I was loading the high crypto image (Which is Huge 11MB) and had neglected to upload the RAM to 48MB from its standard 32MB. At this point you should download a smaller image file from CCO and perform the tftpdnld with the smaller image. The symptom I had was that the router would self corrupt the image while trying to "self-decompress" and like you, my upgrade session was completed successfully. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Ravi Kumar Sent: Tuesday, February 06, 2001 11:00 PM To: [EMAIL PROTECTED] Subject:2600 router - critical situation hi friends I am in deep trouble yesterday i downloaded 12.0 IOS into my 2610 router from my TFTP server. downloading was successful. in fact i deleted old version while upgrading. after that my router is not booting at all. what to do? please help me. bye ravee Get free email and a permanent address at http://www.netaddress.com/?N=1 _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Strange problem with Cisco 2501 routers

On startup, the routers behave normal, but after the "Press RETURN to get started" message, the routers come up with errors about the ethernet and serial interfaces, restarts and then hang up completely. Thinking that the problem may be with the DRAM, Flash or software, I have replaced these with ones from other Cisco 2501 routers in good working condition, but the problem remained the same.

If I do a sh frame-relay lmi and don't see see the Num Status msgs Rcvd and the Num Status Enq Sent incrementing plus I do a sh frame-relay pvc and the status is inactive. Does this mean cable or interface problem. I am thinking cable but not totally sure. I think the cable is a cab-v35mt and cost about a $100usd. I don't want to purchase that unless I know for certain that it is the problem. Actually does anyone know of a place in Seattle that I can get that cable from. Last time I had to order it from Cisco.

I was able to get to the router through PC anywhere and when I checked the configuration it was fine. The LAN side is working fine but when I do a "sh int s0.1" it gives me a line down and protocol down. When I reload the router it gives me Line and protocol up. I give it about 10 seconds and then the line and protocol goes down on the serial interface. What gives ? any ideas ? Could it be flapping ? but then again it is not going back up.

Re: 2600 router - critical situation
The break signal is dependent on the software you are using. For instance, if you are using Procomm, it is Alt + B, so that might be another one to try. I haven't had any experience with other terminal software recently, so I can't think of anything else there. Also, try hitting those key combinations several times. I've noticed that under the right conditions, it takes a while for the break to take effect. Keep us informed and we'll try to help you out however we can.

Seems to be hundreds of vendors out there!!! Pierre-Alex -- -- -- NMap Port scanner Details A new version of NMap has been released. Nmap is used for security auditing, and the new version improves performance, stability and adds more features. Some of the new features are: 1) Fast parallel pinging of all the hosts on a network to determine which ones are up. You can use the traditional ICMP echo request (ping), TCP ACK packet, or TCP SYN packet to probe for responses. By default it uses both ACKs ICMP pings to maximize the chance of sneaking through packet filters. There is also a connect() version for under-privileged users. The syntax for specifying what hosts should be scanned is quite flexible. 2) Improved port scans can be used to determine what services are running. Techniques you can use include the SYN (half-open) scan, FIN, Xmas, or Null stealth scans, connect scan (does not require root), FTP bounce attack, and UDP scan. Options exist for common filter-bypassing techniques such as packet fragmentation and the ability to set the source port number (to 20 or 53, for example). It can also query a remote identd for the usernames the server is running under. You can select any (or all) port number(s) to scan, since you may want to just sweep the networks you run for 1 or 2 services recently found to be vulnerable. 3) Remote OS detection via TCP/IP fingerprinting allows you to determine what operating system release each host is running. This functionality is similar to the awesome queso program, although nmap implements many new techniques. In many cases, nmap can narrow down the OS to the kernel number or release version. A database of ~100 fingerprints for common operating system versions is included, thanks to a couple dozen beta testers who worked on the last 19 private beta releases. 4) TCP ISN sequence predictability lets you know what sequence prediction class (64K, time dependent, "true random", constant, etc.) the host falls into. A difficulty index is provided to tell you roughly how vulnerable the machine is to sequence prediction. 5) Decoy scans can be used. The idea is that for every packet sent by nmap from your address, a similar packet is sent from each of the decoy hosts you specify. This is useful due to the rising popularity of stealth port scanning detection software. If such software is used, it will generally report a dozen (or however many you choose) port scans from different addresses at the same time. It is very difficult to determine which address is doing the scanning, and which are simply innocent decoys.

Re: yet another designated router question..
One DR per multiacess subnet, and an optional BDR. Definitely not one per area. I was a reviewer of the first edition, but not the second. This question has no ideal answer, because "ethernet segment" isn't as precise as I'd like. Do bridged segments count (remember OSPF multicasts, not broadcasts)? How about multiple VLANs on the same physical segment (each will need a DR)? What if there are secondary subnets on the physical segment (results can be flaky. Avoid.)? Hi, Isn't the Designated Router the one on a broadcast type domain that all the routers decide should control the OSPF conversations to avoid everybody doing it thus reducing traffic.

RE: Another 802.3 and Ethernet Question
I am also confused about the question itself. The basic default behavior of Cisco routers is to try to identify the protocol type of a frame, and send it either to the bridging code or the router code for that protocol on that interface. If the protocol type is not supported, drop the frame. I don't know this, but I can reasonably assume that IP protocol identification is hard-coded for the Ethernet II IP Ethertype and for 802.2 IP. IP might be treated as a special case, of which the router is agnostic about encapsulation Still, the encapsulation should be meaningful if and only if appropriate routing or bridging is enabled for the interface. ARP has a protocol type field so that wouldn't seem like the reason. Okay, I have a guess...a total W.A.G., and I wasn't able to back it up with some quick research, but here it is: The answer to this has something to do with ARP packets. My guess is that they assume the presence of Ethernet_II frames when constructing ARP packets and these would be inoperable if some other ethernet frame were being used. That would explain why the default *had* to be Ethernet_II. If ARP breaks, IP over ethernet breaks. Am I right?? I'm going to keep digging to see if I can find some more details about this. I may be chasing down the wrong street. Let me know if I'm even close! :-) John OK, Leigh Anne, you're just going to have to come out and tell us what you are getting at. The suspense is killing me. ;-) The only time I've ever configured an Ethernet encapsulation, it has been part of the ipx network command. As we know, Novell mucked things up and supports four frame types, so being able to configure the frame type is necessary for IPX. A unique feature of IPX is that you can configure multiple networks on a single segment. Each of them must have a different encapsulation. In fact that is how you support networks with devices configured for different encapsulations. I don't even know that you can configure the encapsulation for IP on Ethernet on a router. Can you? Or is that what you're getting at. IP doesn't care. With IP, 99% of the world uses Ethernet V2 (dest, src, EtherType). I just tried to change it on my PC and I couldn't, although I think I have seen that capability on other PCs. But my guess is that if I did change it, the router could still handle it.

Some other companies and protocols had made some changes. The default was used as it was the most common.

She addressed the issue of WHY Ethernet_II is the default frame type selected for IP, but didn't examine why IP requires a default frame type in the first place. IPX uses a default frame type because different Ethernet encapsulations are not able to co-exist within an IPX network -- however different Ethernet encapsulations (Ethernet_II and Ethernet 802.3) ARE able to co-exist within an IP network. As such, what is the importance of a default Ethernet encapsulation for IP? That's what I've been challenging John to think about. Once he understands where the default Ethernet encapsulation comes into play, he could answer his question as to whether there "would there be a good reason to change to a different frame type, or would we only benefit from a different frame type in a non-IP environment or mixed environment". -Original Message- From: Tony van Ree [mailto:[EMAIL PROTECTED]] Sent: February 6, 2001 5:06 PM To: [EMAIL PROTECTED]; John Neiberger; [EMAIL PROTECTED] Subject: RE: Another 802.3 and Ethernet Question Hi, I'm sorry I did not cover the rest of the ethernat frame types.

RE: Another 802.3 and Ethernet Question
What about when the router itself is generating the ARP? I need to find more details about how the ARP packet is constructed. I see a little bit about it in my CIT study guide, but I'd like more details, specifically about the protocol field and its options. If there were no default encapsulation type, I'm thinking that the router would not be able to construct ARP packets. But then we would all just have to learn to add something like "encapsulation arpa" to our ethernet configs. I still don't really see why there *has* to be a default, except that it might lessen the configuration burden on us. I am also confused about the question itself. The basic default behavior of Cisco routers is to try to identify the protocol type of a frame, and send it either to the bridging code or the router code for that protocol on that interface. If the protocol type is not supported, drop the frame. I don't know this, but I can reasonably assume that IP protocol identification is hard-coded for the Ethernet II IP Ethertype and for 802.2 IP. IP might be treated as a special case, of which the router is agnostic about encapsulation Still, the encapsulation should be meaningful if and only if appropriate routing or bridging is enabled for the interface. ARP has a protocol type field so that wouldn't seem like the reason. Okay, I have a guess...a total W.A.G., and I wasn't able to back it up with some quick research, but here it is: The answer to this has something to do with ARP packets. My guess is that they assume the presence of Ethernet_II frames when constructing ARP packets and these would be inoperable if some other ethernet frame were being used. That would explain why the default *had* to be Ethernet_II. If ARP breaks, IP over ethernet breaks. Am I right?? I'm going to keep digging to see if I can find some more details about this. I may be chasing down the wrong street. Let me know if I'm even close! :-) John OK, Leigh Anne, you're just going to have to come out and tell us what you are getting at. The suspense is killing me. ;-) The only time I've ever configured an Ethernet encapsulation, it has been part of the ipx network command. As we know, Novell mucked things up and supports four frame types, so being able to configure the frame type is necessary for IPX. A unique feature of IPX is that you can configure multiple networks on a single segment. Each of them must have a different encapsulation. In fact that is how you support networks with devices configured for different encapsulations. I don't even know that you can configure the encapsulation for IP on Ethernet on a router. Can you? Or is that what you're getting at. IP doesn't care. With IP, 99% of the world uses Ethernet V2 (dest, src, EtherType). I just tried to change it on my PC and I couldn't, although I think I have seen that capability on other PCs. But my guess is that if I did change it, the router could still handle it. Priscilla At 12:33 PM 2/7/01, Tony van Ree wrote: Hi, I understood it to tell me that there is a common method used by a number of manufacturers and protocols. Some other companies and protocols had made some changes. The default was used as it was the most common. Ethernet_II had been around for quite a while before the 802.3 and almost all devices manufacturers ethernet cards and the like could handle Ethernet_II but not necessarily 802.3. Maybe I mis understood. Teunis On Tuesday, February 06, 2001 at 05:36:32 PM, [EMAIL PROTECTED] wrote: I did read Priscilla's post. She addressed the issue of WHY Ethernet_II is the default frame type selected for IP, but didn't examine why IP requires a default frame type in the first place. IPX uses a default frame type because different Ethernet encapsulations are not able to co-exist within an IPX network -- however different Ethernet encapsulations (Ethernet_II and Ethernet 802.3) ARE able to co-exist within an IP network. As such, what is the importance of a default Ethernet encapsulation for IP? That's what I've been challenging John to think about. Once he understands where the default Ethernet encapsulation comes into play, he could answer his question as to whether there "would there be a good reason to change to a different frame type, or would we only benefit from a different frame type in a non-IP environment or mixed environment". -Original Message- From: Tony van Ree [mailto:[EMAIL PROTECTED]] Sent: February 6, 2001 5:06 PM To: [EMAIL PROTECTED]; John Neiberger; [EMAIL PROTECTED] Subject: RE: Another 802.3 and Ethernet Question Hi, I'm sorry I did not cover the rest of the ethernat frame types.

RE: Strange problem with Cisco 2501 routers
Do you have a TFTP server on the segment maybe with a file net-conf? It could be pulling a bad configuration file from a tftp server. Also it might be trying to pull a IOS image from a TFTP server that is not there. It might have a boot system tftp command in the config. I assume you just got these and you are experiencing the problem. Try going into ROM mode and change the Configuration register to ignore the start up config file (confreg 0x142). reload the router and see what the config look like. I have a feeling it is looking for something off a TFTP server. If you want you can make a copy of the config and then do a write erase. Change back the Config Register to 0x2102 (Router#config-reg 0x2102). Reload the router and see if you get the same error.

Hi All, I've got a 2511 that I have had problems with, and I have managed to fix it.

So now I'm scratching my head, wondering where I could get another daughterboard for this 2511. It is not under warranty or service contract.

Re: The best place to put the access lists
The best place for ACL's is at the access layer. You want to deny or permit packets the outer-most level you have control of. If you wait for their packets to get into the core of your network, then you have already compromised your network's security. If you do it at the router that your customer connects to, you can deny things like routing protocols and subnets that need not penetrate your network. The best solution for security is a firewall. If security is a mission critical application, a PIX should be used instead of ACL's.

I passed the CCIE Written yesterday morning. I had taken the CCIE written about a month ago but the test crashed and I had to fight with Cisco and Prometric for a month before I could take it again for free. I read Caslow's book, Routing TCP/IP Vol. 1 by Jeff Doyle, the token ring white papers and the exam cram book. The token ring white papers were very helpful in understanding bridging because I do not work with it at all. I already had my CCNP and CCDP so this also helped and I would not recommend taking the CCIE written without having finished at least your CCNP certification. I also took the certification zone test before I took the exam last month, and it was not that helpful. I am planning to take schedule the lab for this summer. I am going to purchase the Solutions Labs and the ccbootcamp labs today and use them to study. I work for a Cisco reseller so I have plenty of equipment sitting around to use for study labs.

Re: The best place to put the access lists
I agree that access lists should be placed at the access layer. However, I'd argue that a firewall is a minimum component of security, not a best solution for security. Those companies that depend solely on a firewall for security could be in for a rude awakening. Additionally, if security is mission critical, a PIX wouldn't be my recommendation. It's decent at what it does, but lacks the ability to truly interrogate the network traffic. Craig At 10:16 AM 2/7/2001 -0600, you wrote: The best place for ACL's is at the access layer. You want to deny or permit packets the outer-most level you have control of. If you wait for their packets to get into the core of your network, then you have already compromised your network's security. If you do it at the router that your customer connects to, you can deny things like routing protocols and subnets that need not penetrate your network. The best solution for security is a firewall. If security is a mission critical application, a PIX should be used instead of ACL's.

RE: Access-List Statement Clearification Request
Question 1: As John pointed out in Question 2, access lists in the range of 1-99 are reserved for IP standard access control lists and are to be used in conjunction with the "ip access-group" statement. Access lists in the range of 1-99 cannot be used in conjunction with the "ipx access-group" statement--even though your router might permit you to enter the command without returning an error message during the configuration. When you issue a "show running-config" statement, the command will not appear in the configuration. Other than that, your interpretation of the statement is correct. Question 2: You can re-use access lists numbers on the same, or on various interfaces. For example, you could see this in a running-config: interface ethernet 0 ip address 192.1.1.1 255.255.255.0 ip access-group 1 in ip access-group 1 out interface serial 0 ip address 172.16.1.1 255.255.0.0 ip access-group 1 in ip access-group 1 out The only other thing I'd point out, is that if you're going to specify IPX access lists on an interface, don't forget to configure the IPX network (command: "IPX network net_address") that is connected to the interface--and of course, IPX routing (command: "IPX routing) must be enabled before you can do this. -- Leigh Anne -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John Neiberger Sent: February 7, 2001 10:24 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: Access-List Statement Clearification Request Comments inline. --- Start --- Statement: "You can only assign one access list per interface, per protocol, or per direction" Question 1: Would this be correct as to an overall general understanding of this statement? interface ethernet 0 ip address 192.1.1.1 255.255.255.0 ip access-group 1 in ip access-group 2 out ipx access-group 3 in ipx access-group 4 out Yes, this is correct.

Ethernet uses Carrier Sense Multiple Access/ Collision Detection (CSMA/CD). Token Ring uses token passing. Ethernet will send the packet out and detect if there is a collision. Token Ring will not send out the information unless it can insert the information in a empty frame (token). In an Ethernet network, if the information is not for that host, the host will discard the information. In a Token Ring network, if the information is not for that host, the host will past the frame onto the next host. There is never a collision in a Token Ring network. That is why you must have a MAU in a Token Ring Network. In the physical level, the roll/crossover cable will not work because the interface does not operation at the same ohms. I presume you used a DB15/RJ45 converter to connect to the router then use a roll cable to connect to the NIC. You must use a media filter to connect to the router to use the RJ45 connector on the NIC. There is alot more difference between Ethernet and Token Ring.

First, let's look at what you have, 198.144.163.1/25. That gives you 126 usable addresses, 198.144.163.1-126. Now, you want to further divide that into two subnets of 62 usable addresses each. To do this, simply add another bit to the subnet mask. This will give you the following: 198.144.163.0/26 and 198.144.163.64/26 Your usable address range is 1-62 and 65-126. This is because you can't use the .0, .63, .64, and .127 addresses. There are a LOT of threads in the archives about subnetting.

RE: 7000 router power issue ?
You're OK. I believe that the 7000 AC power supply is rated at 700 watts. volts times amps equals power. So power divided by voltage equals amps. Assuming normal electrical service in an US home 700/120 = 5.83 amps. The true current draw would be determined by the number and type of cards in the router. I have never taken a current reading of a working system. There is a large noisy blower in the chassis. The whole is a useful space heater for cold winter nights. The standard US cord has a plug end that fits a regular 15 Amp receptacle. I have run a 7000 at home. Most electrical receptacles are rated at 15 amps. A normal electrical branch circuit is rated at 20 amps - usable at 16 amps for continuous duty (over three hours). So all should be well. The problem is that normal electrical branch circuits have several (up to ten) receptacles on the circuit. The total load cannot exceed 16 amps. -Original Message- From: Rah Sta [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 07, 2001 11:54 AM To: [EMAIL PROTECTED] Subject: 7000 router power issue ?

RE: Another 802.3 and Ethernet Question
At 10:35 AM 2/7/01, Howard C. Berkowitz wrote:
I am also confused about the question itself.
The basic default behavior of Cisco routers is to try to identify the
protocol type of a frame, and send it either to the bridging code or
the router code for that protocol on that interface. If the
protocol type is not supported, drop the frame.
I don't know this, but I can reasonably assume that IP protocol
identification is hard-coded for the Ethernet II IP Ethertype and for
802.2 IP. IP might be treated as a special case, of which the router
is agnostic about encapsulation Still, the encapsulation should be
meaningful if and only if appropriate routing or bridging is enabled
for the interface.
That would be my assumption also. And, it is probably hard-coded to
recognize the EtherType for ARP also.
There were some cases of TCP/IP stacks using 802.3/802.2 and SNAP for IP
and ARP. They weren't very popular. But if you had some devices using them,
then you would have to configure the router to send ARPs that way. There is
also something called an HP Probe that accomplishes the same thing as ARP
in a non-standard way.
So there is an interface "arp {arpa | probe | snap}" command. I doubt that
it's used much. Encapsulation is much more of an issue for Novell.
This discussion has lost its steam. We might want to end it ;-)
Priscilla
ARP has a protocol type field so that wouldn't seem like the reason.
Okay, I have a guess...a total W.A.G., and I wasn't able to back it
up with some quick research, but here it is:
The answer to this has something to do with ARP packets. My guess
is that they assume the presence of Ethernet_II frames when
constructing ARP packets and these would be inoperable if some other
ethernet frame were being used.
That would explain why the default *had* to be Ethernet_II. If ARP
breaks, IP over ethernet breaks.
Am I right?? I'm going to keep digging to see if I can find some
more details about this. I may be chasing down the wrong street.
Let me know if I'm even close! :-)
John
OK, Leigh Anne, you're just going to have to come out and tell us
what you
are getting at. The suspense is killing me. ;-)
The only time I've ever configured an Ethernet encapsulation, it has been
part of the ipx network command. As we know, Novell mucked things up and
supports four frame types, so being able to configure the frame type is
necessary for IPX. A unique feature of IPX is that you can configure
multiple networks on a single segment. Each of them must have a different
encapsulation. In fact that is how you support networks with devices
configured for different encapsulations.
I don't even know that you can configure the encapsulation for IP on
Ethernet on a router. Can you? Or is that what you're getting at. IP
doesn't care.
With IP, 99% of the world uses Ethernet V2 (dest, src, EtherType). I just
tried to change it on my PC and I couldn't, although I think I have seen
that capability on other PCs. But my guess is that if I did change
it, the
router could still handle it.

Design - looks like it's in limbo right now, will it ever come back? 6. prospective Security track - Qualification exam beta ended 3 months ago and no word yet if it will go production or when/if there will be a Security Lab Exam available.

RE: Another 802.3 and Ethernet Question
At 10:35 AM 2/7/01, Howard C. Berkowitz wrote:
I am also confused about the question itself.
The basic default behavior of Cisco routers is to try to identify the
protocol type of a frame, and send it either to the bridging code or
the router code for that protocol on that interface. If the
protocol type is not supported, drop the frame.
I don't know this, but I can reasonably assume that IP protocol
identification is hard-coded for the Ethernet II IP Ethertype and for
802.2 IP. IP might be treated as a special case, of which the router
is agnostic about encapsulation Still, the encapsulation should be
meaningful if and only if appropriate routing or bridging is enabled
for the interface.
That would be my assumption also. And, it is probably hard-coded to
recognize the EtherType for ARP also.
There were some cases of TCP/IP stacks using 802.3/802.2 and SNAP for IP
and ARP. They weren't very popular. But if you had some devices using them,
then you would have to configure the router to send ARPs that way. There is
also something called an HP Probe that accomplishes the same thing as ARP
in a non-standard way.
So there is an interface "arp {arpa | probe | snap}" command. I doubt that
it's used much. Encapsulation is much more of an issue for Novell.
This discussion has lost its steam. We might want to end it ;-)
Priscilla
I have long been of the opinion that certain networking problems are
insoluble without doctoral-level intervention. In at least some of
them, the specific doctor required would be named Kevorkian.
ARP has a protocol type field so that wouldn't seem like the reason.
Okay, I have a guess...a total W.A.G., and I wasn't able to back it
up with some quick research, but here it is:
The answer to this has something to do with ARP packets. My guess
is that they assume the presence of Ethernet_II frames when
constructing ARP packets and these would be inoperable if some other
ethernet frame were being used.
That would explain why the default *had* to be Ethernet_II. If ARP
breaks, IP over ethernet breaks.
Am I right?? I'm going to keep digging to see if I can find some
more details about this. I may be chasing down the wrong street.
Let me know if I'm even close! :-)
John
OK, Leigh Anne, you're just going to have to come out and tell us
what you
are getting at. The suspense is killing me. ;-)
The only time I've ever configured an Ethernet encapsulation,
it has been
part of the ipx network command. As we know, Novell mucked things up and
supports four frame types, so being able to configure the frame type is
necessary for IPX. A unique feature of IPX is that you can configure
multiple networks on a single segment. Each of them must have
a different
encapsulation. In fact that is how you support networks with devices
configured for different encapsulations.
I don't even know that you can configure the encapsulation for IP on
Ethernet on a router. Can you? Or is that what you're getting at. IP
doesn't care.
With IP, 99% of the world uses Ethernet V2 (dest, src,
EtherType). I just
tried to change it on my PC and I couldn't, although I think I have seen
that capability on other PCs. But my guess is that if I did change
it, the
router could still handle it.

Maybe I mis understood.

That's what I've been challenging John to think about. Once

his question as to whether there "would there be a good reason
