Description

This check will monitor the rx_signal_power and the tx_signal_power of Extreme Networks optical modules (SFP).

This plugin requires at least firmware version 30.x. It has not been tested with earlier versions.

There is currently a bug in Extreme Networks' firmware. The "etsysEntitySfpSensorState" returns a value of 6 (highAlarm) instead of 4 (normal). This error only occurs in SNMP queries and not in the CLI. To resolve the issue, you need at least firmware version v31.7.1.4-patch1-77 or v32.3.x.
