•
Specify a virtual circuit using the DLCI number.
•
Use the brief keyword to display abbreviated PVC information.
•
Use the optional delta keyword to specify that baselined statistics are to be shown.
•
Field descriptions
•
DLCI—DLCI number
•
interface—Identifies an interface in slot/port:channel/subchannel format or a
subinterface in slot/port:channel/subchannel.subinterface format
•
PVC status—Status of the circuit; valid states are active and inactive.
•
Number of circuit status inactive transitions—number of times a circuit came down
because of error conditions
•
Time since creation—Time since the PVC was created
•
last status change—Time since the PVC status last changed
•
In pkts—Number of incoming packets received on the circuit
•
Out pkts—Number of outgoing packets transmitted on the circuit
•
In bytes—Number of input bytes received on the circuit
•
Out bytes—Number of output bytes received on the circuit
•
In FECN pkts—Number of packets received with the forward explicit congestion
notification (FECN) bit set. The FECN bit is set by a network to notify the user that
congestions may be experienced by data traffic in the direction of the frame carrying
the FECN bit. The FECN bit is set by the network (not by the transmitting user), and
there is no obligation for end systems to take any action regarding the FECN bit.
•
Out FECN pkts—Number of packets transmitted with the FECN bit set
•
In BECN pkts—Number of packets received with the backward explicit congestion
notification (BECN) bit set. The BECN bit is set by a network to notify the user that
congestions may be experienced by data traffic in the opposite direction of the frame
carrying the BECN bit. The BECN bit is set by the network, and there is no obligation
for end systems to take any action regarding the BECN bit.
•
Out BECN pkts—Number of packets transmitted with the BECN bit set
•
In DE pkts—Number of packets received with the discard eligibility (DE) bit set. When
the DE bit is set, it indicates that the frame is discarded in preference to other frames
without the DE bit set. The DE bit may be set by the network or the user. Once it is
set, it cannot be reset by the user.
•
Out DE pkts—Number of packets transmitted with the DE bit set
•
Dropped packets—Number of dropped packets
•
