TFTP from 5500 to a half duplex machine [7:14894]
Hi all, I am facing a strange problem with the WS-X5012 ethernet module on the 5500 switch. Cisco TFTP server is installed on a machine with 10/100Mbps ethernet card which is connected to the 5500 switch. This switch has a 10BaseT Ethernet module (WS-X5012) and SupIII supervisor engine.(WS-X5530). I need to copy the CatOS image from the switch to the TFTP server. If I copy the image to a machine connected to the 10/100Ethernet module (WS-X5224) then the copy completes successfully. However If I copy the CatOS image from the switch to the TFTP server installed on a machine connected to the WS-X5012 module (telco connectors) then the operation does not complete successfully.(even though no error is reported either on the switch or on the TFTP server). Ironically If I copy an image from this TFTP server (connected to WS-X5012) to the switch it works fine. Another thing I noticed was that on the WS-X5012 module even though we can set the duplex setting of ports to full duplex, the ports function normally only if the duplex is set to half duplex Thanks and Regards ... _ For Rs. 2,000,000 worth of Aptech scholarships click below http://events.rediff.com/aptechsch/scholarship.htm Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=14894t=14894 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: Protection against smurf attaque [7:14634]
no ip directed-broadcast only prevents your network from being used as a smurf amp. What you want to cut down on a smurf attack on your network is: ip verify unicast reverse-path Also, if you are running BGP with your ISP(s) you can establish a NULL_ROUTE non-transitive community with them beforehand to route attack traffic to the bit bucket. When you notice an attack underway, your router speaking bgp with the ISP peer can advertise the /32 target with this community. Once this propagates, the ISP ibr will drop the attack traffic at ingress to the ISP network. Note that if the attack is well advanced, or your WAN link low bandwidth to begin with, you may have already lost the bgp peering session. For this scenario, keep a low bw ddr link that you can use to setup a peering session and pass this advertisement. Of course, this blackholes whichever host is under attack so you are accomplishing the DoSer's work for him/her. It does keep your network up while you are on hold waiting for someone clueful in your ISP's NOC and prevents excessive consumption of $ for the link. Best regards, Geoff Zinderdine CCNP MCP CCA SOB --- Paul Borghese wrote: I would like to protect my router against smurf attaque. For that I have to set up a CAR on my serial interface. But I want to know how to determine the proper amount of bandwidth for icmp packets for the CAR (I have a 8Mb/s bandwidth interconnection to the Internet). By trail and error I have determined a bandwidth of 128 kb/s.

Cisco IOS 12.x and later has the command on by default. If you are the end receipient of a smurf attack, you will need to work with your Internet Service Provider to limit the bandwidth of echo-replies being sent to your network. Filtering on your router does no good as the attack is designed as a denial-of-service attack to fill your internet access with garbage. Once it hits your router it is too late. You will need to use CAR on the router before your internet connection. I hope this helps! Paul Borghese [EMAIL PROTECTED] __ Do You Yahoo!?

don't know if you have already received an answer to this, but one good source is the CCO configuration guides. in the case of SMDS you can read it at: http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/smds.htm the quote you provide does talk about the physical ( carrier ) level, and with SMDS there are means of configuring it from the carrier side as a series of point to point links or as a single multipoint domain. SMDS group addresses allow a single address to refer to multiple CPE stations, which specify the group address in the Destination Address field of the PDU. The network makes multiple copies of the PDU, which are delivered to all members of the group. Group addresses reduce the amount of network resources required for distributing routing information, resolving addresses, and dynamically discovering network resources. SMDS group addressing is analogous to multicasting on LANs. in your quote, I believe that the interface referred to is the physical interface, i.e. the interface connecting to the SMDS CPE - probably a(n) HSSI. make sense?

RE: EIGRP's interpretation of NBMA and disabling [7:14912]
I'd say that that's close Chuck... but it doesn't say how to disable physical multicasting. It shows the alternative for SMDS. And since I'm not that up on SMDS, I'm more interested in NBMA from the perspective of EIGRP. Right now I'm too busy to do any sort of deep investigation--just if anyone knew the answer as to how to disable physical multicasting and why you'd want to do it, that would have been a bonus.

Re: EIGRP's interpretation of NBMA and disabling [7:14912]
Leigh Anne, There is a neighbour statement in EIGRP just like OSPF and RIP. If you configure an interface as passive, Multicast Hellos are NOT sent on that interface. However, neighbor statements will send unicast hellos and will attempt to form adjacenties. Even if its over a passive interface. I have used this in RIP and OSPF but not EIGRP. I don't have a lab anymore so maybe someone can test this. Could the passive interface command be what they are talking about when it means disabling multicast?

Since you're concerned about redundancy, have you verified that the two providers you have selected are using different physical media to transport your data to the US?

Re: 3660 IOS recovery -Extremely important [7:14616]
Hi, I had a similar issue on a 3640 also. I tried to do a remote IOS upgrade and there were issues. The easiest way out of your situation is if you have a pcmcia card with the flash you want. This I think would be the easiest and quickest way to recover your IOS. If you don't have this card, I do not believe you can do a ftfpdnld on a 3600 but don't quote me on this. Otherwise, you need to troubleshoot what is wrong with your xmodem configs. It may be as simple as having the wrong type cable between your computer and router. I would also run the dev command to see what you got in your router. If time is an issue, you could swap your flash with another router to get your customer up and work on the suspect flash in your shop. I hope this helps and wish you luck. Let me know what happens...

Re: 3660 IOS recovery -Extremely important [7:14616]
Oops... sorry about the mispelling. I meant tftpdnld not ftfpdnld mondo wrote in message ... Hi, I had a similar issue on a 3640 also. I tried to do a remote IOS upgrade and there were issues. The easiest way out of your situation is if you have a pcmcia card with the flash you want. This I think would be the easiest and quickest way to recover your IOS. If you don't have this card, I do not believe you can do a ftfpdnld on a 3600 but don't quote me on this. Otherwise, you need to troubleshoot what is wrong with your xmodem configs. It may be as simple as having the wrong type cable between your computer and router. I would also run the dev command to see what you got in your router. If time is an issue, you could swap your flash with another router to get your customer up and work on the suspect flash in your shop. I hope this helps and wish you luck. Let me know what happens...

Slightly OT: LLQ on a 7513 RSP4?? [7:14928]
Okay, this is really ticking me off. I upgraded the IOS on our main 7513 to 12.1(5a)E1 [before it became deferred] so that I could do CBWFQ and LLQ. However, while attempting to apply the service policy to an interface, the router informed me that LLQ could only be done on VIP interfaces with dCEF enabled. Very frustrating, especially since I could not find anything on CCO that mentioned this. Then, after months of waiting, I upgraded to 12.2(3) expecting this issue to be resolved. Again, it will only allow LLQ on VIP interfaces. Good grief! I can do this on a measily 2600 but an RSP4 can't do LLQ?? This is nuts, and I really need to find a way to do it. Do any of you have any experience with this? Is there some version out there that I've been missing that will allow an RSP4 to do LLQ?

Restrictions on Protocol level in Cisco Pix Firewall [7:14930]
Hi All I have a scenario where I need to limit the commands of a particular protocol through the Pix. Consider, for example, putting restriction on ftp or smtp so that only specific commands for these protocols such as only the GET command working for ftp. Is this possible in the Pix.
