SNMP Commands (Cont.)
Command Function
snmp-server host
This command specifies the
recipient of a Simple
Network Management
Protocol notification
operation.
Use the no form to remove
the specified host.
Syntax:
snmp-server host host-addr community-string [version {1 | 2c}]
no snmp-server host host-addr
• host-addr - Internet address of the host (the targeted recipient). (Maximum
host addresses: 5 trap destination IP address entries)
• community-string - Password-like community string sent with the notification
operation. Although you can set this string using the snmp-server host
command by itself, we recommend that you define this string using the snmp-
server community command prior to using the snmp-server host command.
(Maximum length: 32 characters)
• version - Specifies whether to send notifications as SNMP v1 or v2c traps.
Default Settings:
• Host Address: None
• SNMP Version: 1
Command Mode: Global Configuration
Command Usage: If you do not enter an snmp-server host command, no notifi-
cations are sent. In order to configure the switch to send SNMP notifications,
you must enter at least one snmp-server host command. In order to enable mul-
tiple hosts, you must issue a separate snmp-server host command for each
host.
The snmp-server host command is used in conjunction with the snmp-server
enable traps command. Use the snmp-server enable traps command to specify
which SNMP notifications are sent globally. For a host to receive notifications, at
least one snmp-server enable traps command and the snmp-server host com-
mand 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.
The switch can send SNMP version 1 or version 2c notifications to a host IP
address, depending on the SNMP version that the management station sup-
ports. If the snmp-server host command does not specify the SNMP version, the
default is to send SNMP version 1 notifications.
Example:
Console(config)#snmp-server host 10.1.19.23 batman
Console(config)#
snmp-server enable traps
This command enables this
device to send Simple Net-
work Management Protocol
traps (SNMP notifications).
Use the no form to disable
SNMP notifications.
Syntax:
[no] snmp-server enable traps [authentication | link-up-down]
• authentication - Keyword to issue authentication failure traps.
• link-up-down - Keyword to issue link-up or link-down traps.
Note: The link-up-down trap can only be enabled/disabled via the CLI.
Default Setting: Issue authentication and link-up-down traps.
Command Mode: Global Configuration
Command Usage: If you do not enter an snmp-server enable traps command,
no notifications controlled by this command are sent. In order to configure this
device to send SNMP notifications, you must enter at least one snmp-server
enable traps command. If you enter the command with no keywords, both
authentication and link-up-down notifications are enabled. If you enter the com-
mand with a keyword, only the notification type related to that keyword is
enabled.
The snmp-server enable traps command is used in conjunction with the snmp-
server host command. Use the snmp-server host command to specify which
host or hosts receive SNMP notifications. In order to send notifications, you
must configure at least one snmp-server host command.
Example:
Console(config)#snmp-server enable traps link-up-down
Console(config)#
