Hello,

looking at the output below:

*Jul 14 08:49:32.159: DHCPD: Sending DHCPOFFER to client 01a4.b239.4805.6f (172.16.130.11).

and what you posted earlier:

interface Vlan67
vrf forwarding Telephone
ip address 172.16.30.1 255.255.255.0

check if you did not simply make a typo somewhere. The DHCP offer is for 172.16.130.11, while the Vlan interface has IP address 172.16.30.1, which is a different subnet.

I dont see any reference to any dhcp server in you configuration, either on the distribution or access switch so where is this server located also i don’t see any voice vlan appended to the switch access port for the phone? -switchport voice vlan x
