Configuring Virtual LAN Tag Properties for CMC

VLANs are used to allow multiple virtual LANs to co-exist on the same physical network cable and to segregate the
network traffic for security or load management purposes. When you enable the VLAN functionality, each network
packet is assigned a VLAN tag.

Configuring VLAN Tag Properties for CMC Using RACADM

1. Enable the VLAN capabilities of the external chassis management network:
racadm config -g cfgLanNetworking -o
cfgNicVLanEnable 1
2. Specify the VLAN ID for the external chassis management network:
racadm config -g cfgLanNetworking -o cfgNicVlanID <VLAN id>
The valid values for <VLAN id> are 1– 4000 and 4021– 4094. Default value is 1.
For example:
racadm config -g cfgLanNetworking -o cfgNicVlanID
