Viewing the RMON History Table
The History Table page displays interface specific statistical network samplings. Each table entry represents all counter values compiled during a single sample.
To view RMON history:
- Click Status and Statistics > RMON > History. The History page opens.
- Click History Table. The History Table page opens.
- From the History Entry No. list, select the entry number to display the samples associated with that history entry.
The fields are displayed for the selected sample.
- Owner--History table entry owner.
- Sample No.--Statistics were taken from this sample.
- Drop Events--Dropped packets due to lack of network resources during the sampling interval. This may not represent the exact number of dropped packets, but rather the number of times dropped packets were detected.
- Bytes Received--Octets received that including bad packets and FCS octets, but excluding framing bits.
- Packets Received--Packets received, including bad packets, Multicast, and Broadcast packets.
- Broadcast Packets--Good Broadcast packets received. This number does not include Multicast packets.
- Multicast Packets--Good Multicast packets received.
- CRC Align Errors--CRC and Align errors that have occurred.
- Undersize Packets--Undersized packets (less than 64 octets) received.
- Oversize Packets--Oversized packets (over 1518 octets) received.
- Fragments--Fragments (packets with less than 64 octets) received, excluding framing bits, but including FCS octets).
- Jabbers--Total number of received packets that were longer than 1632 octets. This number excludes frame bits, but includes FCS octets that had either a bad FCS (Frame Check Sequence) with an integral number of octets (FCS Error) or a bad FCS with a non-integral octet (Alignment Error) number.
- Collisions--Collisions received.
- Utilization--Percentage of current interface traffic compared to maximum traffic that the interface can handle.
