Configuring the SNMP Management Interface
SecureStack C3 Configuration Guide 8-39
How SNMP Will Use This Configuration
In order to send a trap/notification requested by a MIB code, the SNMP agent requires the
equivalent of a trap “door”, a “key” to unlock the door, and a “procedure” for crossing the
doorstep. To determine if all these elements are in place, the SNMP agent proceeds as follows:
1. Determines if the “keys” for trap “doors” do exist. In the example configuration above, the
key that SNMP is looking for is the notification entry created with the set snmp notify
command which, in this case, is a key labeled entry1 .
2. Searches for the doors matching such a key. For example, the parameters set for the entry1 key
shows that it opens only the door TrapSink .
3. Verifies that the specified door TrapSink is, in fact, available. In this case it was built using the
set snmp targetaddr command. This command also specifies that this door leads to the
management station 192.168.190.80 , and the “procedure” ( targetparams ) to cross the doorstep
is called v2ExampleParams .
4. Verifies that the v2ExampleParams description of how to step through the door is, in fact,
there. The agent checks targetparams entries and determines this description was made with
the set snmp targetparams command, which tells exactly which SNMP protocol to use and
what community name to provide. In this case, the community name is mgmt .
5. Verifies that the mgmt community name is available. In this case, it has been configured using
the set snmp community command.
6. Sends the trap notification message.
