B-4 APPENDIX B: REMOTE MONITORING (RMON) TECHNOLOGY
Statistics and
axFDDI Groups
The Statistics group records frame statistics for Ethernet and FDDI interfaces.
The information available per interface segment includes:
■ Number of received octets
■ Number of received packets
■ Number of received broadcast packets
■ Number of received multicast packets
■ Number of received packets with CRC or alignment errors
■ Number of received undersized but otherwise well-formed packets
■ Number of received oversized but otherwise well-formed packets
■ Number of received undersized packets with either a CRC or an alignment
error
■ Number of detected transmit collisions
Byte sizes include the 4 byte FCS, but exclude the framing bits. The number
of the packet length counters is shown in Table B-3:
