Chapter 41: IP Interface Commands
An IP address may be used for management access to the router over your network
or to connect the switch to existing IP subnets. An IPv4 address is obtained via
DHCP by default for VLAN 1. You can also manually configure a new address for
other VLANs on the router to enable management access through these VLANs or
to connect the router to existing IP subnets. You can manually configure a specific
IPv4 or IPv6 address, or direct the router to obtain an IPv4 address from a BOOTP
or DHCP server when it is powered on. Both IP Version 4 and 6 addresses can be
defined and used simultaneously to access the router. An IPv6 address can either
be manually configured or dynamically generated. You may also need to a establish
an IPv4 or IPv6 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.
