EOS supports relaxing Layer 1 CLI guards to configure the handling ofunsupported Layer 1 configurations such as incorrect speed and error correction. EOS rejects the unsupported configurations with error messages or prompts for confirmation using warning messages.

Examples

Use the following command to reject an unsupported speed configuration:

switch(config)# system l1
switch(config-system-l1)# unsupported speed action error

When configured with an unsupported speed, the switch returns the following error message:

switch(config-if-ET1/2)# speed 200g-4
% Speed and duplex settings are not compatible with transceiver for interface Ethernet1/2.

Use the following commands to warn and prompt for unsupported speed configuration:

switch(config)# system l1
switch(config-system-l1)# unsupported speed action warn

When configured with an unsupported speed, the switch returns the following warning message:

switch(config-if-ET1/2)# speed 200g-4
! Speed and duplex settings are not compatible with transceiver for interface EthernetX/Y.
Do you wish to proceed with this command? [y/N]

Suppress the prompt asking confirmation with the terminal dont-ask command. Add this configuration for systems using automation for configuration.
