Configuring Port-Based
VLANs
Adding Ethernet Ports to a VLAN
Use the following command to add Ethernet ports to a VLAN.
Perform the following configuration in VLAN view.
For the meanings of the parameters related to the Ethernet ports and the specific
numbering rules of the ports, see
“Port Configuration” on page 35.
The port number preceding the key word to must be smaller than the number
following
to. All ports within the specified range must be of the same type.
The &<1-10> of the command specifies the repetition times of the parameter,
ranging from 1 to 10. In addition, you cannot specify any trunk ports.
By default, the system adds all ports to VLAN1.
Configuring
Protocol-Based VLANs
Table 53 describes how incoming packets are treated when they pass through
ports that are members of both tagged and protocol-based VLANs.
Configuring protocol-based VLANs includes tasks described in the following
sections:
■ Creating and Deleting a VLAN Protocol Type
■ Creating and Deleting the Association Between a Port and a Protocol-Based
VLAN
Protocol-based VLANs are supported only in the 48-port 10/100BASE-T
Auto-sensing FE, 24-port 100BASE-FX MMF FE, 8-port 1000BASE-X GE, and
8-port 10/100/1000BASE-T GE I/O modules.
