Inter-vlan routing not working on the C3750X Layer 3 Switch. Help!!!

Hi all,

Just configured a 3750x switch as a DHCP server for some vlans and even though the ip routing is enabled, I am unable to route between vlans.

Note that the 3750x serves as a core switch that connects through trunking to 2960s accesss switches. VTP v3 is enabled, as well as VTP pruning, all SVIs configured. DHCP gives the respective SVI as gateway for the PCs. The computers connect through IP phones so the ports on the 2960S are on multi-vlan access mode.

I am wondering why I am unable to route between my vlans as I can see all subnets on respective SVIs in the routing table of the switch. I also used the default gateway comand on the 2960S switches so they are able to ping all the SVIs but the PCs on the access ports are not able to do the same and possibly exchange information with each other on different networks.

Thanks in advance for your help.

Regards,

Igor
