Monitoring SNMP

There are several commands that you can access in Junos OS operational mode to monitor SNMP information. Some of the commands are:

  • show snmp health-monitor, which displays the health monitor log and alarm information.
  • show snmp mib, which displays information from the MIBs, such as device and system information.
  • show snmp statistics, which displays SNMP statistics such as the number of packets, silent drops, and invalid output values.
  • show snmp rmon, which displays the RMON alarm, event, history, and log information

The following example provides sample output from the show snmp health-monitor command:

user@switch> show snmp health-monitor

       jnxHrStoragePercentUsed.2                          0 active

The following example provides sample output from the show snmp statistics command:

user@switch> show snmp statistics
