avaya ip office with Catalyst 3560

I have the following config for my switch

int gig0/1  through int gig0/20

WS-C3560X-48PF-S   switchport access vlan 10

  switchport voice vlan 20

The Avaya IP Office (PBX)  is doing the dhcp for the voip. vlan 10 has 10.10.40.0/24 subnet. vlan 20 has 10.10.45.0/24 subnet. My PCs are connected via the VoIP. The issue that I am having is I cannot ping the pbx from any of the PC. I can see its MAC address in the CAM table, Ip routing is enabled.

Each of the VLANs need to have an IP address configured (from the correct rage).

Also, the PCs needs to be set to have their default gateway pointing to the IP address of the switch.

Also, the PBX needs to have its default gateway pointing to the Cisco (or at least a static route for 10.10.40/24 with next hop being the cisco WS-C3560X-48PF-L).

You can check your set up on the switch with the "show ip route" command, to make sure it does have the relevant routes - once you have IP addresses in each VLAN.

Can you post a sanitized config from the switch?  Can the switch ping the VLAN default gateways and the PBX?
