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
enable traps command. Use the
sending of traps or informs and to specify which SNMP notifications are sent
globally. For a host to receive notifications, at least one
command and the snmp-server host command for that host must be enabled.
• Some notification types cannot be controlled with the
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
2. Create a view with the required notification messages
page 22-15).
3. Create a group that includes the required notify view
page 22-12).
4. Allow the switch to send SNMP traps; i.e., notifications
on page 22-7).
5. Specify the target host that will receive inform messages with the snmp-server
host command as described in this section.
To send an inform to a SNMPv3 host, complete these steps:
1. Enable the SNMP agent
2. Create a local SNMPv3 user to use in the message exchange process
("snmp-server user" on page
3. Create a view with the required notification messages
page 22-15).
4. Create a group that includes the required notify view
page 22-12).
5. Allow the switch to send SNMP traps; i.e., notifications
on page 22-7).
