Information
When this command is configured, the VLAN is operationally UP if any of the interfaces
specified in the
track ip command are operationally UP, and the VLAN is operationally
DOWN if none of the tracking interfaces are operationally UP.
If the
track ip command is not configured, the VLAN's Layer 3 operational state depends on
all the members of the VLAN.
The Layer 2 state of the VLAN, and hence the Layer 2 traffic is not affected by the
track ip
command configuration.
