Layer 1 Commands

system l1 module

The system l1 module command enters the configuration mode for Layer 1 parameters. The no and default versions of the command restore the switch to the default settings.

Configuration Mode

System Layer 1 Configuration Mode

Command Syntax

system l1 module linecard linecard_name switch switch_name

Parameters

  • linecard linecard_name - Specify a linecard to configure L1 parameters.
  • switch switch_name - Specify a switch to configure L1 parameters.

Example

  • Use the following command to enter the System L1 Configuration mode and add the linecard, 3, to the configuration:
    switch(config)# system l1
    switch(config-system-l1)# module linecard 3

system l1 module profile

The system l1 module profile command configures Layer 1 module profiles on a switch. The no and default versions of the command remove the configuration from the running-config.

Command Mode

System Layer 1 Configuration Mode

Command Syntax

system l1 module module_name profile profile_name

Parameters

  • system l1 module module_name - Specify the module name to apply the profile. On modular systems, use the parameter Linecard. On a fixed system, use the parameter, switch.
  • profile profile_name - Specify the built-in profile name.

Examples

  • Configure the built-in profile, Uniform-4x100g-2-R, on a modular system with Linecard3, Linecard4, and Linecard6:
    switch(config)# system l1
    switch(config-system-l1)# module Linecard3-4,6 profile Uniform-4x100G2-R
  • Configure the built-in profile, Uniform-4x100g-2-R, on a fixed system:
    switch(config)# system l1
    switch(config-system-l1)# module switch profile Uniform-4x100G2-R

system l1 unsupported

The system l1 unsupported command enters the configuration mode for Layer 1 parameters and configures the response to unsupported L1 configurations. The no and default versions of the command restore the switch to the default settings.

Configuration Mode

System Layer 1 Configuration Mode

Command Syntax

system l1 unsupported [error-correction | speed] action [error | warn]

Parameters

  • error-correction - Specify error correction forwarding on the switch.
  • speed - Specify the speed on the switch.
  • error - Specify to return an error message for unsupported configurations.
  • warn - Specify to return a warning for unsupported configurations.

Examples

  • Use the following command to enter the System L1 Configuration mode and specify to return a warning for unsupported speeds on the switch:
    switch(config)# system l1
    switch(config-system-l1)# unsupported speed action warn
  • When attempting to add an unsupported speed to the switch, EOS returns a warning message:
    switch(config-if-ET1/2)# speed 200g-4
    ! Speed and duplex settings are not compatible with transceiver for interface EthernetX/Y.

show l1 modules profile status

The show l1 modules profile status command displays the status of configured Layer 1 profiles on the switch.

Command Mode

EXEC

Command Syntax

show l1 modules profile status

Examples

  • Use the show l1 modules profile status to display the status. On a modular system, the command returns the following output:
    switch# show l1 modules profiles status
    * Indicates that the configured profile definition has changed
    
    Module    Operational        Configured         Status
    --------- ------------------ ------------------ ------------
    linecard3 Uniform-4x100G-2-R Uniform-4x100G-2-R applied
    linecard4 n/a                Uniform-4x100G-2-R not inserted
    linecard5 n/a                Uniform-4x10G-1    pending
    linecard6 n/a                Uniform-4x10G-1    error
    linecard7 n/a                n/a                applied
  • On a fixed system, the command returns the following output:
    switch# show l1 modules profiles status
    * Indicates that the configured profile definition has changed
    
    Module Operational        Configured         Status
    ------ ------------------ ------------------ -------
    switch Uniform-4x100G-2-R Uniform-4x100G-2-R applied
  • The Status column has one of the following entries:
    • applied - Operational and configured profiles match. No action needed.
    • not inserted - Module not inserted and nothing to configure.
    • pending - Requires a card reinsertion or switch powercycle before module becomes operational. Reboot the switch or simulate reinserting the cards.
    • error - Configured profile on an unsupported module. Double-check the platform compatibility list.
