Protocol-Based Groups to VLAN Mapping
To map a protocol group to a port, the port must be in General mode and not have
DVA configured on it (see
Configuring VLAN Interface Settings
).
Several groups can be bound to a single port, with each port being associated to
its own VLAN.
It is possible to map several groups to a single VLAN as well.
To map the protocol port to a VLAN:
STEP 1
Click VLAN Management > VLAN Groups > Protocol-Based Groups to VLAN. The
Protocol-Based Groups to VLAN
page is displayed.
The currently-defined mappings are displayed.
STEP 2
To associate an interface with a protocol-based group and VLAN, click Add. The
Add Group to VLAN Mapping
page is displayed.
STEP 3
Enter the following fields.
•
Interface—Port or LAG number assigned to VLAN according to protocol-
based group..
•
Group ID—Protocol group ID.
