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:
Enable the SNMP agent (page 4-68).
Allow the switch to send SNMP traps; i.e., notifications (page 4-74).
Specify the target host that will receive inform messages with the snmp-server host command as described in this section.
Create a view with the required notification messages (page 4-77).
Create a group that includes the required notify view (page 4-79).
To send an inform to a SNMPv3 host, complete these steps:
Enable the SNMP agent (page 4-68).
Allow the switch to send SNMP traps; i.e., notifications (page 4-74).
Specify the target host that will receive inform messages with the snmp-server host command as described in this section.
Create a view with the required notification messages (page 4-77).
Create a group that includes the required notify view (page 4-79).
Specify a remote engine ID where the user resides (page 4-75).
Then configure a remote user (page 4-81).
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 batman
