Impact
L2Q - set to "2" (off) If T (the Tagged Flag) is set to
0; set to "1" (on) if T is set to 1.
L2QVLAN - set to the VLAN ID in the TLV.
L2QAUD and L2QSIG - set to the Layer 2 Priority
value in the TLV.
DSCPAUD and DSCPSIG - set to the DSCP value
in the TLV.
A check is made as to whether a reset is necessary
to obtain a new IP address due to a change in the
values of the parameters L2Q or L2QVLAN.
This TLV is ignored if:
the value of USE_DHCP is "0" and the value
●
of IPADD is not "0.0.0.0", or
the Application Type is not 1 (Voice) and is
●
not 2 (Voice Signaling), or
the Unknown Policy Flag (U) is set to 1.
●
MCIPADD will be set to this value if it has not
already been set.
TLSSRVR and HTTPSRVR will be set to this value
if neither of them have already been set.
The default L2Q is set to the value of this TLV. No
change is made to the current L2 tagging, but the
new default value is used on the next reboot. If TLV
= 1, L2Q set to "1" (On). If TLV = 2, L2Q set to "2"
(Off). If TLV = 3, L2Q set to "0" (Auto).
This proprietary TLV can initiate a power
conservation mode. The deskphones that support
this will turn on/off the deskphone backlight and the
backlight of an attached Button Module in response
to this TLV.
Power conservation mode will be enabled if the
received binary Power Source value is 10, and
power conservation mode will be disabled if the
received binary Power Source value is not 10.
Power conservation mode is enabled even if the
deskphone is not powered over Ethernet because
the deskphone sends information about the power
source that it is using in a TIA LLDP MED Extended
Power-Via-MDI TLV; it is assumed that the power
management system intends to conserve local
power as well.
