Configuring RMON Statistics Collection

Configuring RMON Statistics Collection

Context

RMON statistics include Ethernet and history statistics. These statistics collection functions apply to different scenarios:

  • Configure Ethernet statistics collection to continuously collect traffic statistics on an Ethernet interface. Ethernet statistics include the following:
    • Network collisions
    • CRC error packets
    • Undersized or large data packets
    • Broadcast and multicast packets
    • Bytes received
    • Packets received
  • Configure history statistics collection to store the statistics on the specified interface. History statistics include:
    • Bandwidth usage
    • Error packets
    • Total number of packets

Procedure

  • Configure Ethernet statistics collection.
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The interface view is displayed.

    3. Run rmon-statistics enable

      RMON statistics collection is enabled on an interface.

    4. Run rmon statistics entry-number [ owner owner-name ]

      A statistics table is created and an entry is added to the table.

  • Configure history statistics collection.
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The interface view is displayed.

    3. Run rmon-statistics enable

      RMON statistics collection is enabled on an interface.

    4. Run rmon history entry-number buckets number interval sampling-interval [ owner owner-name ]

      A history control table is created and an entry is added to the table.

    NOTE:
    • The RMON standard recommends that each monitored interface should have more than two history control entries. One entry is sampled every 30 seconds while another entry is sampled every 30 minutes.
    • The short sampling interval enables a monitor for sudden changes of traffic modes, and the long sampling interval is applicable if the interface status is relatively stable.
    • Each history control table stores 10 records. When more than 10 records are generated, the old ones are overwritten.
    • To reduce the impact of RMON on system performance, the sampling interval of the history control table should be longer than 10 seconds. An interface cannot be configured with too many entries for the history control table and alarm table.
    • If RMON statistics collection is not enabled on an interface, the number of records in the RMON statistics and history tables is 0.
