[c-nsp] 7940 VLAN's

[David Prall]

Brian,
Caveat - I have no clue if this will work.

The access vlan is untagged, while the voice vlan is tagged.

On the switch define the port as an 802.1Q trunk, set the native vlan to
your user vlan. Define that the only vlans sent on the trunk are the user
and voice vlans.

Now you should startup the phone and see what IP address it received from
the DHCP server.

Let us know what you find out.

>From the documentation it appears that each phone will have to have an
Administrative VLAN configured on them so that they properly Tag the
traffic.

-----------------------------------------
Operational VLAN . Indicates the (Virtual Local Area Network) VLAN in which
the phone is a member. . Obtained through Cisco Discovery Protocol (CDP).
Cannot configure locally.

Administrative VLAN . Indicates the VLAN in which the phone is a member. .
Assigns phone to an auxiliary VLAN. . Used in non-Cisco switched networks.
See the "Configuring VLAN
Settings" section on page 3-15.
