eth add
Adds a logical interface onto an Ethernet port so that the router can provide service to
multiple IP subnets. The
eth add command defines the port number and logical
interface number. Next, use the eth ip addr command to define the IP subnet that
uses the logical interface. For more information, see “IP Subnets” on page 6-1 of the
Technical Reference Guide.
NOTE:
A logical interface 0 always exists for Ethernet port 0 (and for port 1 in a dual-port
router); logical interface 0 cannot be deleted.
Once defined, routes and filters can be created for the new logical interface using the
other eth commands in this section. To list the currently defined logical interfaces, use
the eth list command. To remove a logical interface, use an eth delete command.
NOTE:
This command requires a save and reboot before it takes effect.
