Enabling and
Disabling
Switch 9100 Ports
By default, all ports are enabled. To enable or disable one or more ports,
use the following command:
[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]
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
Enabling
Autonegotiation
To configure the switch to autonegotiate, use the following command:
config ports <portlist> auto on
