On the prompt screen, enter the administrative login information.
After a successful login, the console command-line will be displayed.
Switch>
Use the enable command to enter the privilege mode.
Switch> enable
Use the configure terminal command to enter the configuration mode.
Switch# configure terminal
Use the following command to enable and configure the Cisco SNMP service.
Switch(config)# snmp-server community GokuBlack ro
Switch(config)# snmp-server contact Zamasu <zamasu@dbsuper.com>
Switch(config)# snmp-server location Universe10 – IT Room
Switch(config)# exit
The GokuBlack Community has read-only permission on the Cisco Switch.
The contact person responsible for this Switch was configured as Zamasu.
The location of the equipment was configured as the IT Room of Universe 10.
Don’t forget to save your switch configuration.
Switch# copy running-config startup-config
To test your Cisco SNMP configuration, use the following commands on a computer running Ubuntu Linux.
# apt-get install snmp
# snmpwalk -v2c -c GokuBlack 10.0.129.226
Here is a small sample of the snmpwalk command output.
