96 9600 Series SIP IP Telephones Administrator Guide SIP Release 2.0
Another system value you can administer is VLANTEST. VLANTEST defines the number of
seconds the 9600 IP Series Telephone waits for a DHCPOFFER message when using a
non-zero VLAN ID. The VLANTEST default is “60” seconds. Using VLANTEST ensures that the
telephone returns to the default VLAN if an invalid VLAN ID is administered or if the phone
moves to a port where the L2QVLAN value is invalid. The default value is long, allowing for the
scenario that a major power interruption is causing the phones to restart. Always allow time for
network routers, the DHCP servers, etc. to be returned to service. If the telephone restarts for
any reason and the VLANTEST time limit expires, the telephone assumes the administered
VLAN ID is invalid. The telephone then initiates registration with the default VLAN ID.
Setting VLANTEST to “0” has the special meaning of telling the phone to use a non-zero VLAN
indefinitely to attempt DHCP. In other words, the telephone does not return to the default VLAN.
Note:
Note: If the telephone returns to the default VLAN but must be put back on the
L2QVLAN VLAN ID, you must Reset the telephone. See the Reset procedure in
the Avaya one-X™ Deskphone Edition for 9600 Series SIP IP Telephones

VLAN Separation
VLAN separation is available to control priority tagging from the device on the secondary
Ethernet, typically PC data. The following system parameters control VLAN separation:
● VLANSEP - enables (1) or disables (0) VLAN separation.
● PHY2VLAN - provides the VLAN ID for tagged frames received on the secondary Ethernet
interface.
● PHY2PRIO - the layer 2 priority value to be used for tagged frames received on the
secondary Ethernet interface.
Table 12
provides several VLAN separation guidelines.
