Hello Cisco Gurus
I am having an interesting, albeit, frustrating issue with interoperability between a 3560 48 Port Poe and an HP 5412zl backbone switch. I have 2 VLANS defined 1 is Data and 2 is voice. If I plug a PC and or phone into the HP directly I get a DHCP address for the phone and the PC.
I have a Gigabit uplink port set up
Untagged on the HP for VLAN 1 on the HP side. When I connect a computer to the Cisco switch I can get a computer to get an address but not a phone.
From the switch console I can ping both the computer and phone DHCP servers.
The uplink port is GB 0/1 and the port settings are as follows.
The IP subnet for the phones is 10.55.4.x/24
and data is 10.56.x.x /16
spanning-tree mode mst

I tried hard coding a PC using a 10.55.4.x address and I couldn't ping a thing. If I get a DHCP address on a PC I can ping both 10.55.4 and 10.56.x.x addresses. Its like the Cisco device is totally unaware of the existance of VLAN 2. Any ideas and or suggestions would be extremely helpful. This limitation is holding up a project already behind schedule. Thank you in advance for your feedback.
