Management Port - Nortel Application Switch Installation Manual

16
• Four Small Form Factor Pluggable (SFP) GBIC fiber optic ports (9-12). These ports are
designed to operate at 1000 Mbps and full duplex mode only.
Note: Application Switches support only LC connectors with the SPF GBICs. Do not use
SPF GBICs with MT-RJ connectors.
Dual-Mode Ports
The Application Switch 3408 is equipped with four dual-mode ports (3, 4, 5, 6). These ports have
two interfaces each: 1000 Mbps SFP GBIC and 10/100/1000Base-T Copper. When the 1000 Mbps
SFP GBIC port is selected as the preferred link, it is fixed at 1000 Mbps, full-duplex with
autonegotiation turned on. When the 10/100/1000Base-T copper port is selected as the preferred
link, it can be configured at any speed. However, if 1000 Mbps is selected, autonegotiation must be
turned on. Either interface can be set as the preferred or backup link.
Common Ports
The Application Switch 2000 and 3000 Series are equipped with two types of ports common to all
switch models. This section outlines these common port types.

Management Port

The Management Port is a Fast Ethernet port with two LEDs. This port is used exclusively to
manage the switch. While the switch can be managed from any network port, the Management
Port saves consuming a port that could otherwise be used for processing data and traffic. This port
is isolated from, and does not participate in, the networking protocols that run on the network
ports.
The Management Port must be configured with a static IP address, subnet mask, broadcast address,
default gateway, and must be enabled before it can be used. If this port is disabled, the network
ports are used to perform all switch management (other than the switch management performed
using the console port). If this port is enabled, the factory default settings for some of the
management features remain with the network ports. Defaults can be changed by configuring these
features to permanently use the Management Port, or in some cases, by using the operational
commands to set these options on a one-time basis.
