Command Usage
◆
If you do not enter an
snmp-server host
command, no notifications 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 multiple 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 enable
the sending of traps or informs and 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
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.
◆
Notifications are issued by the switch as trap messages by default. The recipient
of a trap message does not send a response to the switch. Traps are therefore
not as reliable as inform messages, which include a request for
acknowledgement of receipt. Informs can be used to ensure that critical
information is received by the host. However, note that informs consume more
system resources because they must be kept in memory until a response is
received. Informs also add to network traffic. You should consider these effects
when deciding whether to issue notifications as traps or informs.
To send an inform to a SNMPv2c host, complete these steps:
1.
Enable the SNMP agent (page 161).
2.
Create a view with the required notification messages (page 173).
3.
Create a group that includes the required notify view (page 170).
