Global Configuration
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 4-152).
2. Allow the switch to send SNMP traps; i.e., notifications (page 4-159).
