NOTE
The number of entries in a RMON statistics table directly corresponds to the number of ports on a
system. For example, if the system is a 26 port device, there will be 26 entries in the statistics
display.

History (RMON group 2)

All active ports by default will generate two history control data entries per active BigIron RX
interface. An active port is defined as one with a link up. If the link goes down the two entries are
automatically be deleted.
Two history entries are generated for each device:
•
•
The history data can be accessed and displayed using any of the popular RMON applications
A sample RMON history command and its syntax is shown below.
BigIron RX(config)# rmon history 1 interface 1 buckets 10 interval 10 owner nyc02
Syntax: rrmon history <entry-number> interface ethernet <slot/port> | management <num>
You can modify the sampling interval and the bucket (number of entries saved before overwrite)
using the CLI. In the above example, owner refers to the RMON station that will request the
information.
NOTE
To review the control data entry for each port or interface, enter the show rmon history command.

Alarm (RMON group 3)

Alarm is designed to monitor configured thresholds for any SNMP integer, time tick, gauge or
counter MIB object. Using the CLI, you can define what MIB objects are monitored, the type of
thresholds that are monitored (falling, rising or both), the value of those thresholds, and the
sample type (absolute or delta).
An alarm event is reported each time that a threshold is exceeded. The alarm entry also indicates
the action (event) to be taken if the threshold be exceeded.
