Configuration Examples

This section shows examples of configuration commands that specify an event that
generates an SNMP trap and the alarm condition that triggers the event.
The RMON Alarm group allows the SSR to poll itself at user-defined intervals. Alarms
that constitute an event are logged into the Event table that can then be polled by the
management station. The management station is able to poll more network devices this
way, as it only needs to poll the RMON Event table and not the device itself. The
management station can also be sent trap information.
The following examples configure the SSR to create an event when a module is hot
swapped into the chassis or any new IP interface is configured. The managed object
ifTableLastChanged from RFC 2233) has an object identifier (OID) of 1.3.6.1.2.1.31.1.5.0
and the SSR will poll this OID every 5 minutes (300 seconds).
The command line below is an example of an RMON Event group configuration with the
following attributes:
• Index number 15 to identify this entry in the Event control table.
• The event is both logged in the Event table and an SNMP trap generated with the
community string "public".
• Event owner is "help desk".
ssr#(config) rmon event index 15 type both community public description
"Interface added or module hot swapped in" owner "help desk"
The command line below is an example of an RMON Alarm group configuration with the
following attributes:
• Index number 20 to identify this entry in the Alarm control table.
• The OID 1.3.6.1.2.1.31.1.5.0 identifies the attribute to be monitored.
