IP Interface Commands
An IP addresses may be used for management access to the switch over your
network. An IPv4 address for this switch is obtained via DHCP by default. You can
manually configure a specific IPv4 address, or direct the device to obtain an address
from a BOOTP or DHCP server when it is powered on. Both IP Version 4 and
Version 6 addresses can be defined and used simultaneously to access the switch.
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 that exist on another network segment.
