VLAN C OMMANDS
4-245
• When a frame enters a port that has been assigned to a protocol
VLAN, it is processed in the following manner:
- If the frame is tagged, it will be processed according to the
standard rules applied to tagged frames.
- If the frame is untagged and the protocol type matches, the frame
is forwarded to the appropriate VLAN.
- If the frame is untagged but the protocol type does not match, the
frame is forwarded to the default VLAN for this interface.
Example
The following example maps the traffic entering Port 1 which matches the
protocol type specified in protocol group 1 to VLAN 2.
