5.9.4.1.1 Monitor Security Switch RMON Statistics

The RMON Statistics Status Overview page provides an overview of RMON Statistics entries. Each page shows up to 99 entries from the Statistics table, default being 20, selected through the entries per page input field. At the first visit, the web page shows the first 20 entries from the beginning of the Statistics table. The first displayed are the ones with the lowest ID found in the Statistics table.

The RMON Statistics Status Overview page has the following parameters:

  • ID: Indicates the index of Statistics entry
  • Data Source(ifIndex): The port ID which wants to be monitored
  • Drop: The total number of events in which packets were dropped by the probe due to lack of resources
  • Octets: The total number of octets of data (including those in bad packets) received on the network
  • Pkts: The total number of packets (including bad packets, broadcast packets, and multicast packets) received
  • Broadcast: The total number of good packets received that were directed to the broadcast address
  • Multicast: The total number of good packets received that were directed to a multicast address
  • CRC Errors: The total number of packets received that had a length (excluding framing bits but including FCS octets) of between 64 and 1518 octets, inclusive but had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral number of octets (Alignment Error).
  • Undersize: The total number of packets received that was less than 64 octets
  • Oversize: The total number of packets received that was longer than 1518 octets
  • Frag: The number of frames whose size is less than 64 octets received with invalid CRC
  • Jabb: The number of frames whose size is larger than 64 octets received with invalid CRC
