How to enable SNMP on a Cisco IOS device

You can enable SNMP from the Cisco IOS command line. You’ll need Telnet, SSH, or serial (console) access to the Cisco device.

1. Telnet, SSH, or serial (console) into your IOS device.
2. If required, enter global configuration mode by typing enable then entering your escalated privilege credentials.
3. Enter configuration mode by typing configure terminal
4. Issue the following command: snmp-server community community_string RO
   • Note: Replace community_string with your desired community string.
5. Issue the following command:   snmp-server vrf default 
6. Exit configuration mode by typing end
7. Commit running configuration changes to startup configuration memory by typing write memory
8. If you used a community string other than public or private, add it to Auvik by following these steps.

All done! Your Cisco IOS device can now be discovered and monitored using Auvik.
