Displaying Snmp Status - Cisco Catalyst 4500 Series Configuration Manual

Chapter 60 Configuring SNMP

Displaying SNMP Status

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
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 you enter 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 can also use the
other privileged EXEC commands in Table 60-4 to display SNMP information. For information about
the fields in the output displays, see the Cisco IOS Configuration Fundamentals Command Reference,
