Configuring and Validating SNMP

Simple network management protocol (SNMP) applications are used in URWB software for network management functionalities.

The SNMP client sends a request to the SNMP agent. The SNMP agent passes the request to the subagent. The subagent responds to the SNMP agent. The SNMP agent creates an SNMP response packet and sends it to the remote network management station that initiates the request.

Configuring SNMP from CLI

To configure SNMP, use the following CLI commands:

Note

SNMP CLI logic modified for SNMP configuration, before enabling the SNMP feature using CLI, you must configure all SNMP parameters.
Disabling the SNMP feature automatically removes all related configurations.

To enable or disable SNMP functionality, use the following CLI command:

Device#configure snmp [enable | disable]

To specify the SNMP protocol version, use the following CLI command:

Device#configure snmp version {v2c | v3}

To specify the SNMP v2c community ID number (SNMP v2c only), use the following CLI command:

Device#configure snmp v2c community-id <length 1-64>

To specify the SNMP v3 username (SNMP v3 only), use the following CLI command:

Device#configure snmp v3 username <length 32>

To specify the SNMP v3 user password (SNMP v3 only), use the following CLI command:

Device#configure snmp v3 password <length 8-64>

To specify the SNMP v3 authentication protocol (SNMP v3 only), use the following CLI command:

Device#configure snmp auth-method <md5|sha>

To specify the SNMP v3 encryption protocol (SNMP v3 only), use the following CLI command:

Device#configure snmp encryption {des | aes | none}

Possible encryption values are des or aes. Alternatively, enter none if a v3 encryption protocol is not needed.

To specify the SNMP v3 encryption passphrase (SNMP v3 only), use the following CLI command:

Device#configure snmp secret <length 8-64>

To specify the SNMP periodic trap settings, use the following CLI command:

Device#configure snmp periodic-trap {enable | disable}

To specify the notification trap period for periodic SNMP traps, use the following CLI command:

Device#configure snmp trap-period <1-2147483647>

Notification value trap period measured in minutes.

To enable or disable SNMP event traps, use the following CLI command:

Device#configure snmp event-trap {enable | disable}

To specify the SNMP NMS hostname or IP address, use the following CLI command:

Device#configure snmp nms-hostname {hostname |Ip Address}

To disable SNMP configuration, use the following CLI command:

Device#configure snmp disabled

Once you disable SNMP, it clears all the sensitive information including credentials. You have to re-specify all the valid values again to enable SNMP.

Example of SNMP configuration:

CLI for SNMP v2:

Device#configure snmp v2 community-id <length 1-64>
Device#configure snmp nms-hostname hostname/Ip Address
Device#configure snmp trap-period <1-2147483647>
Device#configure snmp periodic-trap enable/disable
Device#configure snmp event-trap enable/disable
Device#configure snmp version v2c
Device#configure snmp enabled

CLI for SNMP v3:

Device #configure snmp nms-hostname hostname/Ip Address
Device#configure snmp trap-period <1-2147483647>
Device#configure snmp v3 username <length 32>
Device#configure snmp v3 password <length 8-64>
Device#configure snmp auth-method <md5|sha>
Device#configure snmp encryption <aes|des|none>
Device#configure snmp secret <length 8-64>
Device#configure snmp periodic-trap enable/disable
Device#configure snmp event-trap enable/disable
Device#configure snmp version v3
Device#configure snmp enabled

Validating SNMP from CLI

To validate the SNMP, use the following show command:

Device# show snmp
