VLAN Configuration

CLI – This example creates protocol group 1 for Ethernet frames using the IP
protocol, and group 2 for Ethernet frames using the ARP protocol.
Mapping Protocols to VLANs
Use the Protocol VLAN System Configuration menu to map a Protocol VLAN Group
to a VLAN.
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 menus
such as the VLAN Static Table (page 3-214) or VLAN Static Membership by Port
menu (page 3-216), 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.
- 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.
Command Attributes
• Protocol Group ID – Protocol Group ID assigned to the Protocol VLAN Group.
(Range: 1-2147483647)
• VLAN ID – VLAN to which matching protocol traffic is forwarded. (Range: 1-4094)
Web – Click VLAN, Protocol VLAN, System Configuration. Enter a protocol group
ID, the corresponding VLAN ID, and click Apply.
