DHCP scope options for Avaya phone

Jeffrey_Bourger — Tue, 22 Dec 2015 02:29:00 GMT

Setting up Summit x440 as DHCP server.
Looking for the syntax, or reference material for Avaya options.
This is the string used in MicroSoft or QIP DHCP.
“MCIPADD=#.#.#.#,MCPORT=1719,TFTPSRVR=#.#.#.#,L2Q=1,L2QVLAN=0″

Maybe this?

configure test dhcp-options code 176 string "MCIPADD=10.8.2.5,MCPORT=1719,TFTPSRVR=10.8.2.5,L2Q=1L2QVLAN=0"

Thank you Jeremy. That will work, I'll ask the client for the IP office IP address. Second question, which is probably a no or at least not best practices. I have a client that has given me one vlan, to use for both voice and data. Let's say 10 devices, all phones, with a pc connected to the back. So, If I tag all the ports, the phones will receive an IP address and see the tag, place the tag on the phone. Question would be would the workstations receive an IP address placed on the back of the phone? I know that if I separate the phone and data connections, I can put the phones on the vlan tagged, the desktop on the vlan untagged and this would work. Thank you.

Hey Jeffrey, If you are going to do multiple VLANS (tagging the Voice VLAN on the required ports) here is the config I use for Avaya on XOS gear

Enable LLDP:
enable lldp ports

Enable LLDP Media Capabilities:
configure lldp port advertise vendor-specific med capabilities

Enable ports to advertise vlan-names:
configure lldp port advertise vendor-specific dot1 vlan-name vlan

Configure LLDP transmit interval to 5 seconds on ports :
configure lldp transmit-interval 5

This will allow for the Phones to dynamically get the tagged VLAN for voice and hand the untagged off to the PC. Hope this also helps you out

Hi Joseph,

After doing all this, do you push any policy or mac auth to the switches? We use a similar setup with native VLAN/tagged voip VLAN, but once we push Port Config Wizard in Policy Manager, it kills the tagged frames.

Any ideas?
