ESRP Environment Tracking

You can configure ESRP to track hardware status. If a power supply fails, if the switch is overheating, or if a non-fully loaded power supply is detected, the priority for the ESRP domain will change to the failover settings.
Note

Note

ExtremeXOS software determines the maximum available power required for the switch by calculating the number of power supplies and the power required by the installed modules. Enabling environmental tracking on the switch without enough power budget causes tracking to fail. In this case, the tracking failure occurs by design.

To configure the failover priority for an ESRP domain:

  1. Set the failover priority using the following command:
    configure esrp esrpDomain add track-environment failover priority
  2. Assign the priority flag precedence over the active ports count using the following command:
    configure esrp esrpDomain election-policy [ports > track > priority | ports > track > priority > mac | priority > mac | priority > ports > track > mac | priority > track > ports > mac | sticky > ports > track > priority | sticky > ports > track > priority > mac | sticky > ports > weight > track > priority > mac | sticky > priority > mac | sticky > priority > ports > track > mac | sticky > priority > track > ports > mac | sticky > track > ports > priority | sticky > track > ports > priority > mac | track > ports > priority | track > ports > priority > mac]
Because the priority of both ESRP domains are set to the same value, ESRP will use the active ports count to determine the master ESRP domain.
