Status and Statistics
RMON
The following statistics are displayed for the selected interface.
• Bytes Received—Octets received, including bad packets and FCS octets, but excluding framing bits.
• Drop Events—Packets dropped.
• Packets Received—Good packets received, including Multicast and Broadcast packets.
• Broadcast Packets Received—Good Broadcast packets received. This number does not include
Multicast packets.
• Multicast Packets Received—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 2000 octets) received.
• Fragments—Fragments (packets with less than 64 octets, excluding framing bits, but including FCS
octets) received.
• Jabbers—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. 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 received.
• Frames of 65 to 127 Bytes—Frames, containing 65-127 bytes that were received.
• Frames of 128 to 255 Bytes—Frames, containing 128-255 bytes that were received.
• Frames of 256 to 511 Bytes—Frames, containing 256-511 bytes that were received.
• Frames of 512 to 1023 Bytes—Frames, containing 512-1023 bytes that were received.
• Frames of 1024 Bytes or More—Frames, containing 1024-2000 bytes, and Jumbo Frames, that
were received.
