asked on Connecting C3560-IPBASEK9-M to existing C2960-LANBASE-M
Hi, I am trying to connect a new C3560-IPBASEK9-M to an older C2960-LANBASE-M. I want to trunk a fast Ethernet port on each and connect them.
We have two other C3560-IPBASE-M switches that are connected this way and seem to work fine.
I have tried to configure the C3560-IPBASEK9-M and the older C2960-LANBASE-M in a similar fashion as the two that are working. I get link lights on both, and can get CDP information. However, I cannot connect to the network through the new C3560-IPBASEK9-M when I plug a laptop into it. Also, I cannot telnet to it.
I saw elsewhere on Experts Exchange that the LANBASE IOS does not support IP routing. I assume this means I cannot use the command ‘ip classless'. Could this be the problem? If so, would it help to reverse the setup (connecting the new C3560-IPBASEK9-M to the fiber network, and then connecting the old C2960-LANBASE-M to the new switch)?

To shorten it, remove any line with a password or identifying information like a circuit id or account number, remove interfaces that aren't the uplink or the port connected to your pc. Post the rest including the show commands I suggested.
also, the 2960 with LANBASE can do static routing. LAN-lite cannot. 3560 can always do routing, but how advanced of routing you can do depends on code level and licensing.

Thanks for your patients. I captured a lot of information that I hope to post today.
Just to clarify, the 2960 is the one with the LANBASE code.
I also briefly tried connecting the new switch straight into the fiber network and taking the old switch out of play (We might just take it out of play permanently). I also had problems connecting to the network with the new switch plugged into fiber. So I am thinking it has something to do with the new switch config.
I have to get permission to post the config. I don't think I will be able to. Is there a certain section that would be helpful or that I should concentrate on?
