Enabling and Disabling Switch Ports
To enable or disable one or more ports, use the following command:
enable ports [<portlist> | all]
disable ports [<portlist> | all]
For example, to disable ports 3, 5, and 12 through 15, use the following command:
disable ports 3,5,12-15
Even though a port is disabled, the link remains enabled for diagnostic purposes.
Configuring Switch Port Speed and Duplex Setting
When configuring the speed and duplex setting for a port, autonegotiation plays a significant role. By
default, the switch is configured to use autonegotiation to determine the port speed and duplex setting
for each port.
The Summit 400-48t has four 1000 Mbps fiber and 48 copper 10/100/1000 Mbps ports. All of the fiber
ports can be configured for automatic failover using the first four copper ports. These ports are called
combination ports because either the fiber port or the copper port is active, but they are never active
concurrently. For a description of cabling for combination ports, see “Uplink Redundancy” on page 27.
For information on configuring combination ports, see “Configuring Automatic Failover for
