Setting up SNMP

Question

I’ve just setup ZABBIX at a computer in my LAN properly and thought it would be good to have SNMP access to my Cisco router. When I look at the settings regarding SNMP in the administration web GUI, I get totally confused about the community parts.

I’ve never heard of this before, so how do I understand the concept of read/write/trap communities and what should I enter in each box as shown below?

Answer

Imagine that community string is the same as ‘password’ when server query SNMP info from client. You should only need to fill the “read community” first.

  • write community string: allows a remote device to modify settings on
    your router.
  • trap community string: is used to send SNMP traps to another device when there is a significant event.
