Ethernet Management Port (NET MGMT)

The NET MGMT port in the management panel of the switch is a separate
routed eth0 interface. The interface is not part of the switching matrix of
the Ethernet line cards, but the CPU on the controller card can route traffic
in or out of the port from the line cards.
Here are the guidelines to using the port:

The port should only be used for initial configuration and
maintenance access to the chassis.
 The NET MGMT port has a standard RJ-45 8-pin connector and
operates at 10, 100, or 1000 Mbps in either half- or full-duplex
mode.
 The cable requirements for the port are the same as for the 10/
100/1000-T ports, listed in Table 2 on page 30. For the port
pinouts, refer to "RJ-45 Twisted Pair Port Pinouts" on page 156.
 The default setting for the port is Auto-Negotiation, which sets the
speed and duplex mode automatically. You may disable Auto-
Negotiation and configure the port manually.

The wiring configuration of the NET MGMT port is set
automatically with automatic MDIX detection. You may disable
automatic MDIX detection and set the wiring configuration
manually.
 The port is referred to as eth0 in the management software.
For instructions on how to configure the NET MGMT port, refer to the
Software Reference for x930 Series Switches.
The Network Management (NET MGMT) port on the switch has two
Status LEDs, described in Table 9.
