See page 984.Related Configuration TasksThe following list contains configuration tasks for SNMP:• Read Managed Object Values on page 985• Write Managed Object Values on page 986• Subscribe to Managed Object Value Updates using SNMP on page 988• Copy Configuration Files on page 113• Manage VLANs using SNMP on page 997• Enable and Disable a Port using SNMP on page 1001• Fetch Dynamic MAC Entries using SNMP on page 1001• Deriving Interface Indices on page 1003• Monitor Port-channels on page 1004Important Points to Remember• Typically, 5-second timeout and 3-second retry values on an SNMP server are sufficient for both LANand WAN applications. If you experience a timeout with these values, increase the timeout value togreater than 3 seconds, and increase the retry value to greater than 2 on your SNMP server.• Group ACLs override user ACLs in SNMPv3 configurations when both are configured and the user ispart of the group.Create a CommunityThe management station generates requests to either retrieve or alter the value of a management object andis called the SNMP manager. A network element that processes SNMP requests is called an SNMP agent.An SNMP community is a group of SNMP agents and managers that are allowed to interact. Communitiesare necessary to secure communication between SNMP managers and agents; SNMP agents do notrespond to requests from management stations that are not part of the community.FTOS enables SNMP automatically when you create an SNMP community and displays Message 1. Youmust specify whether members of the community may only retrieve values (read), or retrieve and altervalues (read-write).To create an SNMP community:Task Command Command ModeChoose a name for the community. snmp-server community name {ro | rw} CONFIGURATION
