with IP and ARP protocol types.
Mapping Protocols to VLANs
Map a protocol group to a VLAN for each interface that will participate in the group.
Command Usage
• When creating a protocol-based VLAN, only assign interfaces using this
configuration screen. If you assign interfaces using any of the other VLAN
commands such as VLAN Static Table (page 3-129) or VLAN Static Membership
(page 3-131), these interfaces will admit traffic of any protocol type into the
associated VLAN.
• 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.
