How to Configure SNMP

Configuring Community Strings

You use the SNMP community string to define the relationship between the SNMP manager and the agent.
The community string acts like a password to permit access to the agent on the switch. Optionally, you can
specify one or more of these characteristics associated with the string:
• An access list of IP addresses of the SNMP managers that are permitted to use the community string to
• A MIB view, which defines the subset of all MIB objects accessible to the given community
• Read and write or read-only permission for the MIB objects accessible to the community
Follow these steps to configure a community string on the switch.
