调低速档enable

Description

Enables/disables automatic speed downshift on an interface that supports downshift, generally 1GBASE-T ports. When enabled, downshift allows an interface to link at a lower advertised speed when unable to establish a stable link at the maximum speed. Downshifting only applies to physical interfaces that are not members of a LAG and is only available when auto-negotiation is enabled. When only one speed is advertised, downshift will not be triggered.

Examples

switch(config-if)#interface 1/1/1switch(config-if)#downshift-enableWarning: this is a non-standard mode for use only when standards-based auto-negotiation is not able to establish a stable link. Enabling this may cause the port to link at a lower than expected speed and should not be used on ports that are members of a LAG. Support calls may require this feature to be disabled Continue (y/n)? switch(config-if)#

启用自动调低速档时:

switch(config-if)#show running-config interfaceinterface 1/1/1 downshift-enable

Disabling automatic speed downshift:

switch(config-if)#interface 1/1/1switch(config-if)#no downshift-enable
