RMON support
39
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 device 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:
• a sampling of statistics every 30 seconds
• a sampling of statistics every 30 minutes
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>
buckets <number> interval <sampling-interval> owner <text-string>
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.
