5548 with voip currently running. There is a DHCP server running on the same subnet. We are trying to test DHCP Relay and set up a separate VLAN. From what we can tell by snooping the traffic is that the request is sent to the DHCP server on the different subnet and the response is sent back to the client. The response can be seen leaving the firewall, going into the switch, but it doesn't make it to the requesting machine. Here is the DHCP Relay configuration:
console# show ip dhcp relay
DHCP relay is Enabled
Option 82 is Enabled
Maximum number of supported VLANs without IP Address is 0
DHCP relay is not configured on any port.
DHCP relay is enabled on Vlans: 12
Servers: 10.28.128.20
interface vlan 12
name "DHCP Relay Test"
ip address 10.10.13.2 255.255.255.0
ip dhcp relay enable
ip route 10.28.128.20 255.255.255.255 10.10.13.1
Ports 44/45 are part of the VLAN 12.
interface gigabitethernet1/0/44
ip dhcp snooping trust
no lldp med enable
switchport access vlan 12
switchport trunk allowed vlan remove 10
Port 45 is the firewall port.
This seems to be a routing issue within the switch, but I'm having troubles confirming/resolving.
