Configuration Examples for SNMP
Configuration Examples for SNMP
Enabling SNMP Versions: Example
This example shows how to enable all versions of SNMP. The configuration permits any SNMP manager to access all
objects with read-only permissions using the community string public. This configuration does not cause the switch to
send any traps.
Switch(config)# snmp-server community public
Permit SNMP Manager Access: Example
This example shows how to permit any SNMP manager to access all objects with read-only permission using the
community string public. The switch also sends VTP traps to the hosts 192.180.1.111 and 192.180.1.33 using SNMPv1
and to the host 192.180.1.27 using SNMPv2C. The community string public is sent with the traps.
Switch(config)# snmp-server community public
Switch(config)# snmp-server enable traps vtp
Switch(config)# snmp-server host 192.180.1.27 version 2c public
Switch(config)# snmp-server host 192.180.1.111 version 1 public
Switch(config)# snmp-server host 192.180.1.33 public
Allow Read-Only Access: Example
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
Configure SNMP Traps: Examples
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
Associating a User with a Remote Host: Example
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
