History (RMON Group 2)
All active ports by default will generate two history control data entries per active Foundry Layer 2 Switch port or
Layer 3 Switch interface. An active port is defined as one with a link up. If the link goes down the two entries are
automatically 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:
Collisions The best estimate of the total number of collisions on this Ethernet
segment.
64 octets pkts The total number of packets received that were 64 octets long.
This number includes bad packets.
This number does not include framing bits but does include FCS
octets.
65 to 127 octets pkts The total number of packets received that were 65 – 127 octets long.
This number includes bad packets.
This number does not include framing bits but does include FCS
octets.
128 to 255 octets pkts The total number of packets received that were 128 – 255 octets long.
This number includes bad packets.
This number does not include framing bits but does include FCS
octets.
256 to 511 octets pkts The total number of packets received that were 256 – 511 octets long.
This number includes bad packets.
This number does not include framing bits but does include FCS
octets.
512 to 1023 octets pkts The total number of packets received that were 512 – 1023 octets
long.
This number includes bad packets.
This number does not include framing bits but does include FCS
octets.
1024 to 1518 octets pkts The total number of packets received that were 1024 – 1518 octets
long.
This number includes bad packets.
This number does not include framing bits but does include FCS
