Re: AVAYA IP telephones Over Cisco Switches

The issue here is that the cisco switch cheats by the use of the voice vlan
which makes the port a trunk port even if it is configured as access.

as per your question the following config is required.
int x/x
switchport access vlan 28 (Data VLAN)
switchport voice vlan 29 (Voice VLAN)

there is no need to make the port native as it is an acccess port.

on the DHCP scope you will need a option 246 with the line "
L2Q=1,L2QVLAN=29,VLANTEST=10" on the data scope only.

The above tells the phone the Voice Vlan is L2QVLAN=29; ie. 29

as stated above the phone reboots but this is not that noticable with newer
phones however the phone does come up on the data VLAN first.

Let me know if you have any issues
