Chapter 33 Configuring SNMP

Displaying SNMP Status

This example shows how to allow read-only access for all objects to members of access list 4 that use the comaccess community string. No other SNMP managers have access to any objects. SNMP Authentication Failure traps are sent by SNMPv2C to the host cisco.com using the community string public.

Switch(config)# snmp-server community comaccess ro 4

Switch(config)# snmp-server enable traps snmp authentication

Switch(config)# snmp-server host cisco.com version 2c public

This example shows how to send Entity MIB traps to the host cisco.com. The community string is restricted. The first line enables the switch to send Entity MIB traps in addition to any traps previously enabled. The second line specifies the destination of these traps and overwrites any previous snmp-server host commands for the host cisco.com.

Switch(config)# snmp-server enable traps entity

Switch(config)# snmp-server host cisco.com restricted entity

This example shows how to enable the switch to send all traps to the host myhost.cisco.com using the community string public:

Switch(config)# snmp-server enable traps

Switch(config)# snmp-server host myhost.cisco.com public

This example shows how to associate a user with a remote host and to send auth (authNoPriv) authentication-level informs when the user enters global configuration mode:

Switch(config)# snmp-server engineID remote 192.180.1.27 00000063000100a1c0b4011b

Switch(config)# snmp-server group authgroup v3 auth

Switch(config)# snmp-server user authuser authgroup remote 192.180.1.27 v3 auth md5

mypassword

Switch(config)# snmp-server user authuser authgroup v3 auth md5 mypassword Switch(config)# snmp-server host 192.180.1.27 informs version 3 auth authuser config Switch(config)# snmp-server enable traps

Switch(config)# snmp-server inform retries 0

Displaying SNMP Status

To display SNMP input and output statistics, including the number of illegal community string entries, errors, and requested variables, use the show snmp privileged EXEC command. You also can use the other privileged EXEC commands in Table 33-6to display SNMP information. For information about the fields in the displays, see the Cisco IOS Configuration Fundamentals Command Reference, Release 12.2.
