Chapter 23 Configuring SNMP
Configuring SNMP
The snmp-server host command specifies which hosts receive the notifications. The snmp-server
enable trap command globally enables the mechanism for the specified notification (for traps and
informs). To enable a host to receive an inform, you must configure an snmp-server host informs
command for the host and globally enable informs by using the snmp-server enable traps command.
To remove the specified host from receiving traps, use the no snmp-server host host global
configuration 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 global configuration
command. To disable a specific trap type, use the no snmp-server enable traps notification-types global
configuration command.
Step 5
snmp-server host host-addr
[traps | informs] [version {1 | 2c | 3
[auth | noauth]}] community-string
[udp-port port] [notification-type]
Specify the recipient of an SNMP trap operation.
• For host-addr, specify the name or Internet address of the host (the
targeted recipient).
• (Optional) Enter traps (the default) to send SNMP traps to the host.
• (Optional) Enter informs to send SNMP informs to the host.
• (Optional) Specify the SNMP version (1, 2c, or 3). SNMPv1 is not
available with informs.
• (Optional) For version 3, select authentication level auth or noauth.
• For community-string, enter the password-like community string
sent with the notification operation.
• (Optional) For udp-port port, enter the UDP port on the remote
device.
• (Optional) For notification-type, use the keywords listed in
Table 23-4 on page 23-10. If no type is specified, all notifications are
sent.
Step 6
snmp-server enable traps
notification-types
Enable the switch to send traps or informs and specify the type of
notifications to be sent. For a list of notification types, see Table 23-4 on
page 23-10 or enter this: snmp-server enable traps ?
To enable multiple types of traps, you must enter a separate snmp-server
enable traps command for each trap type.
Step 7
snmp-server trap-source interface-id (Optional) Specify the source interface, which provides the IP address for
the trap message. This command also sets the source IP address for
informs.
Step 8
snmp-server queue-length length (Optional) Establish the message queue length for each trap host. The
range is 1 to 1000; the default is 10.
Step 9
snmp-server trap-timeout seconds (Optional) Define how often to resend trap messages. The range is 1 to
1000; the default is 30 seconds.
Step 10
end Return to privileged EXEC mode.
Step 11
show running-config Verify your entries.
Step 12
copy running-config startup-config (Optional) Save your entries in the configuration file.
