Connecting C3560-IPBASEK9-M to existing C2960-LANBASE-M
Posted on 2012-12-26
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)?
