www.dell.com | support.dell.com Related Configuration Tasks The following list contains configuration tasks for SNMP: • Read Managed Object Values • Write Managed Object Values • Subscribe to Managed Object Value Updates using SNMP • Copy Configuration Files Using SNMP • Manage VLANs using SNMP • Enable and Disable a Port using SNMP • Fetch Dynamic MAC Entries using SNMP • Deriving Interface Indices Important Points to Remember • Typically, 5-second timeout and 3-second retry values on an SNMP server are sufficient for both LAN and WAN applications. If you experience a timeout with these values, increase the timeout value to greater 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 is part of the group. Create a Community The management station generates requests to either retrieve or alter the value of a management object and is 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. Communities are necessary to secure communication between SNMP managers and agents; SNMP agents do not respond 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. You must specify whether members of the community may only retrieve values (read), or retrieve and alter values (read-write). To create an SNMP community: Task Choose a name for the community.
