Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010, Руководство по настройке

Страница: 161 / 774

■
Use to display statistics about PVCs for Frame Relay layer on a multilink Frame
Relay, POS, serial, or GRE tunnel interface or a specific PVC.
■
Optionally, you can specify an interface using the interface type and specifier.
For more information, see Interface Types and Specifiers in
JUNOSe Command
Reference Guide .
■
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.
