NET MGMT
Ethernet
Management
Port
The switch uses the NET MGMT port as a separate routed eth0 interface.
The interface is not part of the switching matrix of the Ethernet line cards,
but the switch 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 8-pin RJ-45 connector and
operates at 10, 100, or 1000 Mbps in either half- or full-duplex
mode.
 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.
The cable requirements for the port are listed in Table 6.
