Usage Guideline

If the specified speed is not supported by the hardware, error messages will be returned. For the 100BASE-FX

modules, the speed is always fixed at 100Mbps, full duplex, and no-negotiation. No command can change the

settings. For the 1000BASE-SX/LX modules, the speed is always fixed to 1000Mbps and full duplex, and only the

speed 1000

and

speed auto

commands are valid. For a 1000BASE-T connection, if the speed is specified to

1000Mbps, the port must be configured as master or slave. For a 10GBASE-T connection, if the speed is specified

to 10Gbps, the port must be configured as master or slave.

Auto-negotiation will be enabled when the speed parameter is set to

auto

. The advertised capability will be full

duplex mode combined with the specified speeds. The half-duplex mode is not supported on the Switch.

For 10GBASE-R connections, if auto-negotiation is enabled, the system will automatically configure the speed

(1000M or 10G) according to the type of SFP/SFP+.

Example

This example shows how to configure port 1 to only auto-negotiate to 10Mbps or 100Mbps.

Switch# configure terminal

Switch(config)# interface eth1/0/1

Switch(config-if)# speed auto 10,100

Switch(config-if)#

speed auto-downgrade

This command is used to enable automatically downgrading advertised speed in case a link cannot be established

at the available speed. Use the

form of this command to disable it.

speed auto-downgrade

no speed auto-downgrade

Parameters

None.

Default

By default, this option is disabled.

Command Mode

Interface Configuration Mode.

Command Default Level

Level: 12.

Usage Guideline

Use this command to enable automatically downgrading advertised speed in case a link cannot be established at

the available speed.
