Associates an LLT device "tag" with device via the network-id. If an LLT device tag (as specified in the /etc/llttab file) differs from the name of the network interface as shown in "ifconfig," then DeviceTag must be specified for that interface.
For example: in the common case, /etc/llttab contains:
link lan0 /dev/lan:0 - ether - -
link lan1 /dev/lan:1 - ether - -
link-lowpri lan0 /dev/lan:0 - ether - -
In the above case, DeviceTag does not need to be specified. However, if /etc/llttab contains:
link link1 /dev/lan:0 - ether - -
link link2 /dev/lan:1 - ether - -
link-lowpri spare /dev/lan:0 - ether - -
And,
Device@galaxy = { lan=0, lan1=1, lan2=2 }
DeviceTag needs to be specified as:
DeviceTag@galaxy = { spare=2 }
