By default, the Summit switch is configured to use autonegotiation to determine the

port speed and duplex setting for each port. You can select to manually configure the

duplex setting and the speed of 10/100 Mbps ports, and you can manually configure

the duplex setting on Gigabit Ethernet ports.

Fast Ethernet ports can connect to either 10Base-T or 100Base-T networks. By default,

the ports autonegotiate port speed. You can also configure each port for a particular

speed (either 10 Mbps or 100 Mbps).

Gigabit Ethernet ports are statically set to 1 Gbps, and their speed cannot be modified.

All ports on the Summit switch can be configured for half-duplex or full-duplex

operation. By default, the ports autonegotiate the duplex setting.

To configure port speed and duplex setting, use the following command:

config ports <portlist> auto off {speed [10 | 100 | 1000]} duplex [half

| full]

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

config ports <portlist> auto on

Flow control is supported only on Gigabit Ethernet ports. It is enabled or disabled as

part of autonegotiation. If autonegotiation is set to off, flow control is disabled. When

autonegotiation is turned on, flow control is enabled.
