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)?
