snmp-server host
The snmp-server host command is used with the snmp-server enable traps global configuration
command. Use the snmp-server enable traps command to specify which SNMP notifications are sent
globally. For a host to receive most notifications, at least one snmp-server enable traps command and
the snmp-server host command for that host must be enabled. Some notification types cannot be
controlled with the snmp-server enable traps command. For example, some notification types are
always enabled. Other notification types are enabled by a different command.
The no snmp-server host command with no keywords disables traps, but not informs, to the host. To
disable informs, use the no snmp-server host informs command.
Examples This example shows how to configure a unique SNMP community string named comaccess for traps and
prevent SNMP polling access with this string through access list 10:
Switch(config)# snmp-server community comaccess ro 10
Switch(config)# snmp-server host 172.20.2.160 comaccess
Switch(config)# access-list 10 deny any
This example shows how to send the SNMP traps to the host specified by the name myhost.cisco.com.
The community string is defined as comaccess:
Switch(config)# snmp-server enable traps
Switch(config)# snmp-server host myhost.cisco.com comaccess snmp
This example shows how to enable the switch to send all traps to the host myhost.cisco.com by using the
community string public:
Switch(config)# snmp-server enable traps
Switch(config)# snmp-server host myhost.cisco.com public
You can verify your settings by entering the show running-config privileged EXEC command.
