EEM Script to Manually flap the error disabled interface due to "link-oam-session-down" once the Rx Power on the interface recovers.
A router interface generally doesnt send an RFI when the RX power drops below certain levels.
To mitigate that, one can enable CFM to monitor the RX state and errdisable the interface in question.
If the interface is put into error-disabled state once the Rx power on the interface is below the Rx power threshold. It is required to bring the interface back up automatically once the Rx power on the interface recovers.
This script will help managing that automatically without any manual intervention.
Following is logic used by EEM script:
1. Monitor Rx power of Err-disabled inerface every minute.
2. Once Rx Power recovers, it flaps the interface.
