4507E+R Routing?


We recently added a 4507E+R switch to our infrastructure.  Before this we used fixed switches at our access layer.  I am having a problem with getting the 4507 "pingable" via our management vlan.  I have the 4507 trunked back to our 5548 layer 3 core switches.  The trunk comes up and VTP sends the VLAN information to the 4507.  I configured our mangement vlan on the 4507 with a ip address and mask, just like I always do but I cannot ping the switch, nor can the switch ping out.  I then configured one of the physical interfaces with an ip address and mask associated with our management vlan subnet and connected it to a physical port on a 3560 we have in the wire closet.  I placed the 3560 interface in the correct vlan.  I can ping the switch via this interface, but cannot ping the vlan interface.  Not sure what I might be doing wrong.  We are allowing all VLANs across the trunk.  We are using redundant Sup7e and have two of the 10G interfaces from each Supervisor in a single Etherchannel going back to our 5548 switches.

Any help would be appreciated.

I think it would be better if you can supply the configs of the switches?


4507E+R Routing?

  Does the 4500 have routing turned on ?  If no then you must have a ip  default-gateway"  command on it pointing to the routing interface of your management vlan . If you have ip routing turned on then instead of a default gateway command you must add a default static route pointing to routing interface of your management vlan.
