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. Tagged frames with a VLAN ID of zero (priority-tagged frames) will either be:

-forwarded without being changed (preferred), or

-changed before they are forwarded such that the VLAN ID of the forwarded frame is equal to the PHY2VLAN value and the priority value is equal to the PHY2PRIO value.

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.

Frames received on the secondary Ethernet interface will not be changed before forwarding. In other words, tagging is not added or removed, and the VLAN ID and priority of tagged frames is not changed.

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.

Tagged frames with a VLAN ID of zero (priority-tagged frames) will either be:

-forwarded to the secondary Ethernet interface or the telephone as determined by the forwarding logic of the Ethernet switch (preferred), or

-dropped.
