Definition
The count of valid frames received by the port. A valid
frame is defined as a data frame which is not counted by
any of the error counters.
The count, in octets, of valid frames received by the port.
The sum of all octets in the null addressed frames (during
training) and the following faulty frames that have been
received by the hub: IPM Frames Received, Oversize
Frames Received, Data Rate Mismatches, and Data Error
Frames Received.
The count of frames received with any of the following
errors: FCS, bad symbol, symbol balance, undersize, or
bad end-of-packet marker.
Broadcast frames are frames that all devices in a
network must receive
Multicast frames, like broadcast frames, must be
processed by more systems/devices than a simple
"unicast" frame.
The count of frames received with an invalid packet
marker.
The total number of frames received that were larger
than the maximum valid frame size for the VG network
frame type (Ethernet or Token Ring).
The number of times the port has entered the training
state.
The count of high priority frames received on the port.
The count includes both valid and invalid high priority
frames as well as high priority training frames, but does
not include normal priority frames that were priority
promoted.
The count in octets of all high priority frames received on
the port.
The count of normal priority frames received on the port.
The count includes both valid and invalid normal priority
frames as well as normal priority training frames.
The count in octets of all normal priority frames received
on the port.
Frames received by this port that have an address with all
zeros. Such frames are valid during the 802.12 port
training process.
