Table 8: VLAN Separation Rules
If
Then
VLANSEP is “0”
(Off/Disabled),
OR
the telephone is
not tagging frames,
OR
the telephone is
tagging frames with a
VLAN ID equal to
PHY2VLAN.
Frames received on the secondary Ethernet
interface will not be changed before
forwarding. For example, tagging is not added
or removed and the VLAN ID and tagged
frames priority are not changed. The Ethernet
switch forwarding logic determines that frames
received on the Ethernet line interface are
forwarded to the secondary Ethernet interface
or to the telephone without regard to specific
VLAN IDs or the existence of tags.
VLANSEP is “1” (On/Enabled)
All tagged frames received on the secondary
Ethernet interface are changed before
forwarding to make the VLAN ID equal to the
PHY2VLAN value and the priority value equal
to the PHY2PRIO value.
Untagged frames received on the secondary
Ethernet interface are not changed before
forwarding.
VLANSEP is “1”
(On/Enabled)
AND
the telephone is
not tagging frames,
OR
if the telephone is
tagging frames with a
VLAN ID equal to
PHY2VLAN,
OR
if the PHY2VLAN
value is zero.
The Ethernet switch forwarding logic
determines that frames received on the
Ethernet line interface are forwarded to the
secondary Ethernet interface or to the
telephone without regard to specific VLAN IDs
or the existence of tags.
VLANSEP is “1”
(On/Enabled)
AND
the telephone is
tagging frames with a
VLAN ID not equal to
PHY2VLAN,
AND
the PHY2VLAN
value is not zero.
Tagged frames received on the Ethernet line
interface will only be forwarded to the
secondary Ethernet interface if the VLAN ID
equals PHY2VLAN.
Tagged frames received on the Ethernet line
interface will only be forwarded to the
telephone if the VLAN ID equals the VLAN ID
used by the telephone.
Untagged frames will continue to be forwarded
or not forwarded as determined by the
Ethernet switch forwarding logic.
