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 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 host command for that host must be enabled.
Some notification types cannot be controlled with the
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:
Enable the SNMP agent
1.
Create a view with the required notification messages
2.
Create a group that includes the required notify view
3.
Allow the switch to send SNMP traps; i.e., notifications
4.
Specify the target host that will receive inform messages with the
