Re: Silly Question - Curious to know
I know Cisco has some way that they can tell just from the serial number. I've never really tried, but I bet if you compared 2-3 2500 serial numbers you'd get a good idea (probably something like QYY for quarter & year made). -- Jason Roysdon, CCNP+Security/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ Cisco resources: http://r2cisco.artoo.net/ ""RamG"" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > > Hello Gang, > > Is it possible to find how old is a router based on the show version or any > other output. > > Thanks > > > RamG _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Simple (silly) question on PING [7:51580]
Hi all, Just two simple but annoying PING questions. 1. Why is it that on a broadcast medium, you can issue ping 224.0.0.5 and have all OSPF routers respond (according to CCO), but when I do a simple ping 192.168.10.255 on the subnet, no replies are seen from all the interfaces on this subnet? I know you'll say my brain is getting fried from too much "rack exposure". 2. Using a crossover to connect two Ethernet interfaces, I can ping say RtrA's e0 from RtrB, but can't ping RtrB's e0 from RtrA. I know some of you on the list have seen this before and have had a really crystal-clear explanation for this.

RE: Simple (silly) question on PING [7:51580]
Just want to follow up on my first question. It turned out to be a misbehaving interface, i.e. Layer 1 issue. You do get a reply with a broadcast Ping from each host in the subnet. However, in spite of the one router interface giving me issues, I'm Still trying to TRACE the logic as to how a second router can elicit a PING reply from the first router when Router1 cannot initiate the PING, in spite of the fact that both have each other's ARP table Aware of each other. If only the "debug ip icmp" would give you an Error output when the PINGs don't succeed. Thanks. Elmer P.S.

It does output data even when the interface fails to actually send the packet. Also, put a protocol analyzer on the network. Analyzers make better troubleshooting tools than routers do. You said you can ping RtrA's e0 from RtrB, but can't ping RtrB's e0 from RtrA. This is indeed strange. Once you have fixed the physical-layer issues, check for access lists. That's one of the few things I can think of that would cause this problem. Also, check subnet masks. A router interface could receive a ping request and reply to it just fine, even its subnet mask is wrong. But it might fail to send a ping correctly if its subnet mask is wrong. Actual behavior when there are L1-L3 problems and misconfigurations can be pretty strange. It's often a waste of time to try to figure out the logic because the behavior may be inherently illogical under error conditions. Unless your job is to write the error-handling software routines, why ask why? Just fix the problem. That's the advice I have been giving to network admins for years and it has often helped them be more efficient. :-) Priscilla > Thanks. > Elmer > P.S.
