Class 3 Statistics

The Class 3 Statistics table includes:

Error Statistics

Port errors indicate that a port is not operating correctly. Use this data to isolate
problems with port and link operations. The statistics in this table include:
88
Four Byte Words Rx
The number of four-byte words received.
Four Byte Words Tx
The number of four-byte words transmitted.
Received Frames
The number of Class 3 frames received by this port from its attached port.
Transmitted Frames
The number of Class 3 frames transmitted by this port to its attached port.
Discarded Frames
The number of Class 3 frames discarded, including multicast frames with bad
D_IDs.
The switch increments this count when it discards a frame that cannot be
routed. This occurs most frequently when a destination becomes unavailable
without the source realizing the destination is unavailable. There are no
thresholds for this value. Typically, this occurs when the destination is not
available due to the destination device's action.
Four Byte Words Rx
The number of four-byte words received.
Four Byte Words Tx
The number of four-byte words transmitted.
Link failures
A link failure was recorded in response to a not operational sequence (NOS),
protocol timeout, or port failure. At the Hardware View, a yellow triangle
appears to indicate a link incident, or a blinking red and yellow diamond
appears to indicate a port failure.
