Table 8: VLAN Separation Rules
| If |
|
Then |
| VLANSEP is “0” or "2" (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. |
