Configuring High Availability VLANs

Assigning and Removing Egress Ports
The following subsections describe how to assign to and remove egress ports from a high availability
VLAN with the vlan port-mac egress-port command.
Note. Using the vlan port-mac egress-port command will change a standard VLAN to a high availability
VLAN. Standard VLAN commands do not apply to high availability VLANs.
Assigning Egress Ports
To assign egress ports to a high availability VLAN you use the vlan port-mac egress-port command by
entering vlan, followed by the VLAN’s ID number, port-mac egress-port, the slot number of the port, a
slash (/), and the port number.
For example, to add egress port 1/5 to high availability VLAN 20 you would enter:
-> vlan 20 port-mac egress-port 1/5
You can also add multiple egress ports by entering vlan, followed by the VLAN’s ID number, port-mac
egress-port, the slot number of the first port, a slash (/), the port number of the first port, a space, the slot
number of the second port, a slash, and the port number of the second port. Additional ports can also be
added by specifying their slot number, a slash, and their port number preceded by a space.
Note. Egress ports that belong to the same high availability VLAN do not need to be sequential and can be
on different second-generation NI modules.
For example, to add egress port 1/5, 6/2, and 8/3 to high availability VLAN 20 you would enter:
-> vlan 20 port-mac egress-port 1/5 6/2 8/3
You can also add a range of egress ports by entering vlan, followed by the VLAN’s ID number, port-mac
egress-port, the slot number of the first port, a slash (/), the port number of the first port on the NI, a
hyphen (-), and the last port on the NI.
For example, to add egress port 3/4 through 3/8 to high availability VLAN 20 enter:
-> vlan 20 port-mac egress-port 3/4-8
You can add multiple and ranges of egress ports in the same command line. For example, to add egress
ports 1/5, 3/4 through 3/8, 6/2, and 8/3 to high availability VLAN 20 you would enter:
-> vlan 20 port-mac egress-port 1/5 3/4-8 6/2 8/3
Removing Egress Ports
To remove egress ports from a high availability VLAN, use the no form of the vlan port-mac egress-port
command by entering vlan, followed by the VLAN’s ID number, port-mac no egress-port, the slot
number of the port, a slash (/), and the port number.
For example, to remove egress port 1/5 from high availability VLAN 20 you would enter:
-> vlan 20 port-mac no egress-port 1/5
