OR the deskphone is
not tagging frames,
OR the deskphone is
tagging frames with a
VLAN ID equal to
PHY2VLAN.
AND the deskphone is
not tagging frames,
OR if the deskphone is
tagging frames with a
VLAN ID equal to
PHY2VLAN,
OR if the PHY2VLAN
value is zero.
AND the deskphone is
tagging frames with a
VLAN ID not equal to
PHY2VLAN,
AND the PHY2VLAN
value is not zero.
Then
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 deskphone without regard to specific
VLAN IDs or the existence of tags.
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.
The Ethernet switch forwarding logic
determines that frames received on the
Ethernet line interface are forwarded to the
secondary Ethernet interface or to the
deskphone without regard to specific VLAN
IDs or the existence of tags.
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
deskphone if the VLAN ID equals the VLAN ID
used by the deskphone.
Untagged frames will continue to be forwarded
or not forwarded as determined by the
Ethernet switch forwarding logic.
