Configuring and Validating SNMP
SNMP (simple network monitoring protocol) applications used in Cisco URWB software for network management functionalities.
The following illustration shows the SNMP process. SNMP agent receives a request from SNMP client, and it passes the request to the subagent. The subagent then returns a response to the SNMP agent and the agent creates an SNMP response packet and sends the response to the remote network management station that initiated the request.
Configuring SNMP from CLI
The following CLI commands are used for SNMP (Simple Network Monitoring Protocol) configuration.
Note |
|
Device# configure snmp [enable | disable]
Device#configure snmp version {v2c | v3}
Device#configure snmp v2c community-id <length 1-64>
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 {des | aes | none}
Possible encryption values are des or aes. Alternatively, enter none if a v3 encryption protocol is not needed.
Device#configure snmp secret <length 8-64>
Device#configure snmp periodic-trap {enable | disable}
Device#configure snmp trap-period <1-2147483647>
Notification value trap period measured in minutes.Device#configure snmp event-trap {enable | disable}
Device#configure snmp nms-hostname {hostname |Ip Address}
Device#configure snmp disabled
SNMP is disabled and all sensitive information and credentials have been cleared. Please respecify all valid values to enable
SNMP again.Example of SNMP configuration.
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
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
