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 4-125).
