4 Command Line Interface

To send an inform to a SNMPv3 host, complete these steps:

1.Enable the SNMP agent (page 4-111).

2.Allow the switch to send SNMP traps; i.e., notifications (page 4-116).

3.Specify the target host that will receive inform messages with the snmp-server host command as described in this section.

4.Create a view with the required notification messages (page 4-119).

5.Create a group that includes the required notify view (page 4-120).

6.Specify a remote engine ID where the user resides (page 4-117).7.Then configure a remote user (page 4-122).

•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. If you use the V3 “auth” or “priv” options, the user name must first be defined with the snmp-server user command. Otherwise, the authentication password and/or privacy password will not exist, and the switch will not authorize SNMP access for the host. However, if you specify a V3 host with the “noauth” option, an SNMP user account will be generated, and the switch will authorize SNMP access for the host.

Example

Console(config)#snmp-server host 10.1.19.23 inform retries 10 timeout 30 batman version 2c udp-port 162

Console(config)#
