Chapter 33 Configuring SNMP

Configuring SNMP

Note Though visible in the command-line help strings, the cpu [threshold] keyword is not supported on the Catalyst 3750-E switch. Though visible in the command-line help strings, the cpu [threshold], fru-ctrl, insertion, and removal keywords are not supported on the Catalyst 3560-E switch. To enable the sending of SNMP inform notifications, use the snmp-server enable traps global configuration command combined with the snmp-server host host-addrinforms global configuration command.

You can use the snmp-server host global configuration command to a specific host to receive the notification types listed in Table 33-5.

Beginning in privileged EXEC mode, follow these steps to configure the switch to send traps or informs to a host:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	snmp-server engineID remote	Specify the engine ID for the remote host.
	ip-address engineid-string
Step 3
	snmp-server user username	Configure an SNMP user to be associated with the remote host created in
	groupname {remote host [udp-port	Step 2.
	port]} {v1 [access access-list] v2c	Note You cannot configure a remote user for an address without first
	[access access-list] v3 [encrypted]
		configuring the engine ID for the remote host. Otherwise, you
	[access access-list] [auth {md5 sha}
		receive an error message, and the command is not executed.
	auth-password]}
Step 4
	snmp-server group groupname {v1	Configure an SNMP group.
	v2c v3 {auth noauth priv}} [read
	readview] [write writeview] [notify
	notifyview] [access access-list]
Step 5
	snmp-server host host-addr	Specify the recipient of an SNMP trap operation.
	[informs traps] [version {1 2c 3	• For host-addr,specify the name or Internet address of the host (the
	{auth noauth priv}}]
		targeted recipient).
	community-string [notification-type]
		• (Optional) Enter informs to send SNMP informs to the host.
		• (Optional) Enter traps (the default) to send SNMP traps to the host.
		• (Optional) Specify the SNMP version (1, 2c, or 3). SNMPv1 does
		not support informs.
		• (Optional) For Version 3, select authentication level auth, noauth, or
		priv.
		Note The priv keyword is available only when the cryptographic
		universal software image is installed.
		• For community-string, when version 1 or version 2c is specified,
		enter the password-like community string sent with the notification
		operation. When version 3 is specified, enter the SNMPv3 username.
