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
