CR00021896 VLAN - This enhancement enables administrative (virtual) activation of VLANs.
When a VLAN is activated virtually, its IP interface is active (and therefore
usable) even if all its ports are physically disconnected. The IP interface
associated with the virtually activated VLAN can be operated by protocols
such as OSPF, BGP, and RIP.
VLAN activation is useful for VLANs that are reached through L2TP tunnels
instead of through switch ports.
To turn virtual activation on or off, use the command:
SET VLAN={vlan-name|1..4094|ALL} VIRTActivation ={Yes|No}
The default is no.
To see whether the VLAN has been activated virtually, use the command
show vlan and check the new “Admin Active” field.
This enhancement was previously only available on Rapier, AT-8800,
AT-8600 and AT-8700XL switches. Now it is available on all devices that
support VLANs.
