I've been struggling with this issue for a while now and cannot seem to find where the problem lies.
A basic overview of the infrastructure looks like this...
Cisco 4507 core switch with an ip helper on VLAN 158 (phone vlan) > trunk to Cisco 2960S in IDF > trunk to Aruba MAS 3500 > 9971 on access port and a PC daisy chained through the phone.
The PC gets DHCP IP immediately, but the phone takes a full 5 minutes. If the phone is connected directly to the Cisco 2960S it gets an IP via DHCP immediately.
The port config on the MAS 3500:
interface gigabitethernet "0/0/1"
lldp-profile "lldp-factory-initial"
poe-profile "poe-factory-initial"
aaa-profile "XXXXXX"
switching-profile "vlan250"
no trusted port
VLAN 250 is our default insecure VLAN and we use ClearPass to authenticate and authorize anything the connects to the switch. The AAA profile is assiging the proper phone role and I can see all of that happening via Access Tracker. It's just taking a full 5 minutes every single time a phone needs an IP via DHCP.
I have a helper setup in the MAS 3500, but I dont see where or how I am supposed to apply that to a VLAN or interface.
interface-profile dhcp-relay-profile "Helper"
helper-address X.X.X.X
What am I missing?
Thanks,
Jeff
