IP Interface Commands
There are no IP addresses assigned to this router by default. You must manually
configure a new address to manage the router over your network or to connect the
router to existing IP subnets. You may also need to a establish a default gateway
between this device and management stations or other devices that exist on another
network segment (if routing is not enabled).
This section includes commands for configuring IP interfaces, the Address
Resolution Protocol (ARP) and Proxy ARP. These commands are used to connect
subnetworks to the enterprise network.
