Enabling and Disabling Switch 9100 Ports

55

Enabling and

By default, all ports are enabled. To enable or disable one or more ports,

Disabling

use the following command:

Switch 9100 Ports

 

 

[enable disable] ports <portlist>

 

For example, to disable ports 1, 3, and 5 through 7 on the Switch 9100,

 

enter the following:

 

disable ports 1,3,5-7

 

Even though a port is disabled, the link remains enabled for diagnostic

 

purposes.

Configuring Switch

9100 Port Speed

and Duplex Setting

100/1000BASE-T Ports

By default, the Switch 9100 is configured to use autonegotiation to determine the port speed and duplex setting for each 100/1000BASE-TX port. The 100/1000 Mbps ports can connect to either 100BASE-TX or 1000BASE-T networks. At 1000 Mbps, all ports operate at full-duplex, only.

Autonegotiation is mandatory for a 1000BASE-TX connection, so cannot be disabled if a 1000BASE-TX connection is required. If you do not want your 100/1000BASE-TX ports to autonegotiate you can select to manually configure the speed to 100 Mbps, and the duplex setting to full or half-duplex operation.

To disable autonegotiation and configure port speed and duplex setting for a fixed 100BASE-T connection, use the following command:

config ports <portlist> auto off speed 100 duplex [half

full]

Enabling Autonegotiation

1000BASE-SX Ports

1000BASE-SX ports are statically set to 1 Gbps and full-duplex, neither of which can be modified. By default, the ports autonegotiate. However, you can manually disable autonegotiation, using the following command:

config ports <portlist> auto off duplex full

To configure the switch to autonegotiate, use the following command:

config ports <portlist> auto on
