• CRC & Align Errors -- Number of CRC and Align errors that have occurred on the interface since the device
was last refreshed.
• Undersize Packets -- Number of undersized packets (less than 64 octets) received on the interface since the
device was last refreshed.
• Oversize Packets -- Number of oversized packets (over 1518 octets) received on the interface since the device
was last refreshed.
• Fragments -- Number of fragments (packets with less than 64 octets, excluding framing bits, but including FCS
octets) received on the interface since the device was last refreshed.
• Jabbers -- The total number of packets received that were longer than 1518 octets (excluding framing bits, but
including FCS octets), and 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). The allowed range to detect
jabber is between 20 ms and 150 ms.
• Collisions -- Number of collisions received on the interface since the device was last refreshed
RMON History Control
The RMON History Control page contains information about samples of data taken from ports. For example, the samples

The page includes the following fields:
• History Entry No. -- Entry number for the History Control Table page.
• Source Interface -- Port or LAG from which the history samples were taken.
• Owner (0-20 characters) -- RMON station or user that requested the RMON information.
• Max No. of Samples to Keep (1-65535) -- Number of samples to be saved. The default value is 50.
• Current No. of Samples in List -- The current number of samples taken.
• Sampling Interval (1-3600) -- Indicates in seconds the time that samples are taken from the ports. The
possible values are 1-3600 seconds. The default is 1800 seconds (30 minutes).
