Layer 1 CLI Guard Relaxation

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.

Configuring Layer 1 CLI Guard Relaxation

Configure EOS to handle unsupported Layer 1 configurations with the command, system l1 unsupported. The command supports the following options:

  • speed - Specify the action for unsupported speed configurations.
  • error-correction - Specify the action for unsupported error-correction configurations.
  • error - Configure the switch to reject unsupported configurations with error messages.
  • warn - Configure the switch to warn and prompt for confirmation for unsupported configurations.

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.

Displaying L1 CLI Guard Relaxation Information

To display the current configured actions for unsupported configurations, use the show running-config command:
