VLAN Configuration
Appendix E. BPM (BRIDGE POINT-TO-MULTIPOINT) OPERATION
• VLAN Port Mode – This setting applies only when you set the Working Mode to BPM. Use
the drop-down list to select the port mode as Trunk or Access. Note the following:
o VLAN Trunk Mode is the default mode for BPM where all packets (with and without
VLAN tags) arriving at the CTOG-250 and CDM-840 pass through the system without
modification. A trunked port can pass two or more VLANs on the interface.
o VLAN Access Mode forces the Traffic Interface to carry traffic for only one user-
configured VLAN.
•
Access Port VLAN ID – Enter a valid numeric port ID, from 1 to 4095. This ID is valid only
when Working Mode is set as BPM and the VLAN Port Mode is set to Access.
When the VLAN Port Mode is set to Access, VLAN tagged packets from WAN to LAN having a
VLAN ID that matches the "Access Port VLAN ID" will have the outer VLAN tag removed and
then transmitted by the 'ETHERNET | TRAFFIC | GE' port. In this mode, packets coming in to
the port will be tagged with the "Access Port VLAN ID". If the outermost VLAN tag IDs for
WAN to LAN packets do not match the "Access Port VLAN ID", they will be dropped.
