Ethernet Statistics (RMON)
The PTP 820S platform stores and displays statistics in accordance with RMON and RMON2
standards.
The following transmit statistic counters are available:
•
Transmitted bytes (excluding preamble) in good or bad frames. Low 32 bits.
•
Transmitted bytes (excluding preamble) in good or bad frames. High 32 bits.
•
Transmitted frames (good or bad)
•
Multicast frames (good only)
•
Broadcast frames (good only)
•
Control frames transmitted
•
Pause control frame transmitted
•
FCS error frames
•
Frame length error
•
Oversized frames – frames with length > 1518 bytes (1522 bytes for VLAN-tagged frames)
without errors
•
Undersized frames (good only)
•
Fragments frames (undersized bad)
•
Jabber frames – frames with length > 1518 bytes (1522 for VLAN-tagged frames) with errors
•
Frames with length 64 bytes, good or bad
•
Frames with length 65-127 bytes, good or bad
•
Frames with length 128-255 bytes, good or bad
•
Frames with length 256-511 bytes, good or bad
•
Frames with length 512-1023 bytes, good or bad.
•
Frames with length 1024-1518 bytes, good or bad
•
Frames with length 1519-1522 bytes, good or bad
The following receive statistic counters are available:
•
Received bytes (not including preamble) in good or bad frames. Low 32 bits.
•
Received bytes (not including preamble) in good or bad frames. High 32 bits.
•
Received frames (good or bad)
•
Multicast frames (good only)
•
Broadcast frames (good only)
•
Control frames received
•
Pause control frame received
•
FCS error frames
•
Frame length error
•
Code error
•
Counts oversized frames – frames with length > 1518 bytes (1522 bytes for VLAN-tagged
frames) without errors and frames with length > MAX_LEN without errors
