Re: AVAYA IP telephones Over Cisco Switches

We are using both DHCP option 176 and 242 for our Avaya phones and it works
fine.

Option 176
MCIPADD=192.168.100.11,MCPORT=1719,L2Q=1,L2QVLAN=200,TFTPSRVR=10.10.2.110,IRSTAT=0

Option 242
L2Q=1,L2QVLAN=200,VLANTEST=0

For the switchport configurations we use a mixture of both depending upon
when it was configured

switchport trunke encap dot1q
switchport mode trunk
switchport trunk allowed vlan 100,200

OR

switchport mode access
switchport access vlan 100
switchport voice vlan 200

What about LLDP? Has anyone got this working between Cisco and Avaya? What
IOS version?

Thanks!
