Viewing Statistics 239
Received bytes —The total number of bytes received at this port.
Transmitted bytes —The total number of bytes transmitted at this port.
FCS Errors —The total number of received frames with bad FCS at this port.
Frame Relay Statistics (per DLCI) When you select Frame Relay Statistics from
the QSIM, HSIM, or FAM Performance Management menu, a Frame Relay
Statistics table appears, listing configured virtual circuits. Enter a number
corresponding to one of the listed virtual circuits to display a list of Frame Relay
Statistics for that virtual circuit.
The Frame Relay Statistics screen lists the following statistics (per DLCI):
Received Frames —The total number of received frames with good FCS at this
port.
Transmitted Frames —The total number of successfully-transmitted frames at
this port.
Discarded Invalid Frames —The total number of frames discarded at this port
because they were invalid. Invalid frames are frames that are received with good
FCS but that cannot be processed due to wrong content.
Discarded Congested Frames —The total number of frames discarded at this
port because they were congested. Congested frames are frames that were not
transmitted due to link congestion.
Received bytes —The total number of bytes received at this port.
Received DE —The number of DE (Discard Eligibility) frames received at this port.
Received FECN —The number of FECN (Forward Explicit Congestion Notification)
frames received at this port.
Received BECN —The number of BECN (Backward Explicit Congestion
Notification) frames received at this port.
ATM VC Statistics (per VCI) When you select ATM VC Statistics from the QSIM,
HSIM, or FAM Performance Management menu, an ATM VC Statistics table
appears, listing configured virtual circuits. Enter a number corresponding to one of
the listed virtual circuits to display a list of ATM VC Statistics for that virtual circuit,
The ATM VC Statistics screen lists the following statistics (per VCI):
Port transmit VPI —The transmit VPI for the port side (the side toward the
connector, rather than toward the bus) of the circuit.
Port transmit VCI —The transmit VCI for the port side of the circuit.
Port receive VPI —The receive VPI for the port side of the circuit.
Port receive VCI —The receive VCI for the port side of the circuit.
Received Frames —The total number of received frames with good FCS at this
port.
Transmitted Frames —The total number of successfully-transmitted frames at
this port.
AAL5 Errors— ATM Adaptation Layer 5 (AAL5) Error counter.
Discarded Congested Frames —The total number of congested frames
discarded at this port. Congested frames are frames that were not transmitted due
to link congestion.
