• Jabbers—Received packets that 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. A Jabber packet is defined as an Ethernet frame that satisfies
the following criteria:
- Packet data length is greater than MRU.
- Packet has an invalid CRC.
- Received (Rx) Error Event has not been detected.
• Collisions—Collisions received. If Jumbo frames are enabled, the threshold of Jabber
frames is raised to the maximum size of Jumbo frames.
• Frames of 64 Bytes—Frames, containing 64 bytes that were sent or received.
• Frames of 65 to 127 Bytes—Frames, containing 65-127 bytes that were sent or
received.
• Frames of 128 to 255 Bytes—Frames, containing 128-255 bytes that were sent or
received.
• Frames of 256 to 511 Bytes—Frames, containing 256-511 bytes that were sent or
received.
• Frames of 512 to 1023 Bytes—Frames, containing 512-1023 bytes that were sent or
received.
• Frames of 1024 Bytes or More—Frames, containing 1024-2000 bytes, and Jumbo
Frames, that were sent or received.
To view counters in table view or graphic view:
• Click View All Interfaces Statistics to see all ports in table view.
• Click Graphic View to display these results in graphic form. In this view, you can select
the Time Span for which the results will be displayed and the type of statistic to be
displayed.
RMON History
The RMON feature enables monitoring statistics per interface.
The History page defines the sampling frequency, amount of samples to store and the port
from which to gather the data.
