Chapter 24 Configuring SNMP Configuring SNMP Disabling the SNMP Agent Beginning in privileged EXEC mode, follow these steps to disable the SNMP agent: Step 1 Step 2 Step 3 Step 4 Step 5 Command configure terminal no snmp-server end show running-config copy running-config startup-config Purpose Enter global configuration mode. Disable the SNMP agent operation. Return to privileged EXEC mode. Verify your entries. (Optional) Save your entries in the configuration file. The no snmp-server global configuration command disables all running versions (version 1, version 2C, and version 3) on the device. No specific IOS command exists to enable SNMP. The first snmp-server global configuration command that you enter enables all versions of 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 gain access to the agent • 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 Beginning in privileged EXEC mode, follow these steps to configure a community string on the switch: Step 1 Step 2 Command configure terminal snmp-server community string [view view-name] [ro | rw] [access-list-number] Purpose Enter global configuration mode. Configure the community string. • For string, specify a string that acts like a password and permits access to the SNMP protocol. You can configure one or more community strings of any length. • (Optional) For view, specify the view record accessible to the community. • (Optional) Specify either read-only (ro) if you want authorized management stations to retrieve MIB objects, or specify read-write (rw) if you want authorized management stations to retrieve and modify MIB objects. By default, the community string permits read-only access to all objects. • (Optional) For access-list-number, enter an IP standard access list numbered from 1 to 99 and 1300 to 1999. 78-14982-01 Catalyst 2950 Desktop Switch Software Configuration Guide 24-7
