You use the Console Port to conduct local management sessions with the
switch. Local management sessions require a terminal or PC with a
terminal emulation program, and the management cable that comes with
the switch. The switch does not need an Internet Protocol (IP) address for
local management sessions because they are not conducted over a
network. For instructions, refer to "Starting a Local Management Session"
on page 119.
Note
The first management session of the switch can be either a local
session or a remote session over your network through the NET
MGMT port. For remote management, the switch uses either its
default IP address 192.168.42.42 or an address assigned to it by a
DHCP server. For instructions on remote management sessions,
refer to the Software Reference for x950 Switches, AlliedWare Plus
