CHAPTER 6 CONNECTION MANAGEMENT
IP Subnets
You may configure the router to provide access to multiple IP subnets on the Ethernet
network. (This feature does not apply to IPX or bridged traffic.)
Each IP subnet is referenced as a logical (or virtual) Ethernet interface. You may
define multiple logical interfaces for each physical Ethernet interface (that is, port) in
the router. Each logical interface is referenced by its port number and logical interface
number (port #:logical#).
Logical Interface Commands
To define a logical interface, first use the eth add command; it specifies the port
number and the new logical interface number. You then enter an eth ip addr command
to define the IP address and subnet mask of the IP subnet.
The default logical interface for each port is interface 0; this logical interface 0 always
exists and cannot be deleted. (Other logical interfaces may be deleted using the eth
delete command.)
Stopping and Starting an Interface
You can stop and start a logical interface without rebooting the entire router. To do so,
use these commands:
-> eth stop
Stops a logical Ethernet interface
-> eth start
Starts a logical Ethernet interface
-> eth restart
Stops and restarts a logical Ethernet interface
