SNMP Commands
•
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 (
3. Create a group that includes the required notify view (
4. Allow the switch to send SNMP traps; i.e., notifications (
page 110).
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 (
3. Create a view with the required notification messages (
4. Create a group that includes the required notify view (
5. Allow the switch to send SNMP traps; i.e., notifications (
page 110).
6. Specify the target host that will receive inform messages with the snmp-server host
command as described in this section.
•
The switch can send SNMP Version 1, 2c or 3 notifications to a host IP address, depending on
the SNMP version that the management station supports. If the snmp-server host command
does not specify the SNMP version, the default is to send SNMP version 1 notifications.
•
If you specify an SNMP Version 3 host, then the community string is interpreted as an SNMP
user name. The user name must first be defined with the
command.
Otherwise, an SNMPv3 group will be automatically created by the snmp-server host command
using the name of the specified community string, and default settings for the read, write, and
notify view.
Example
Console(config)#snmp-server host 10.1.19.23 batman
