Displays a DSL port’s performance counters. 1
privilege
Displays the session’s current access privilege level. 1
pvc state < slot-
port >|< slot-port-
vpi/vci >
Displays all PVC’s statistics on a port or only a PVC’s
statistics. 1
rmon stats|history
< giga-port >
Displays Gigabit Ethernet interface link RMON
information. 1
sfp < slot-
port >|< giga-port >
Displays details about the transceiver installed in an
SFP slot on an Ethernet line card or MSC1024GB or
MSC1224GB. 1
sys
Displays the CPU utilization and memory usage
status. 1
user
Displays information on logged in users. * denotes
your session. 1
vdsl inm < slot-port >
curr|15min|
1day
Displays the VDSL port’s impulse noise monitoring
statistics. 1
linebandplan < slot-port >
Displays the connected VDSL upstream/
downstream line band plan. 1
linedata < slot-port >
Displays an VDSL port’s line bit allocation. 1
linegain < slot-port >
Displays the VDSL line gain. 1
linehlog < slot-port >
Displays VDSL line channel characteristics. The
format provides magnitude values in a logarithmic
scale. 1
lineqln < slot-port >
This command displays the Quiet Line Noise level on
a line. This is the rms (root mean square) level of
the noise present on the line for a DMT tone when
no ADSL or VDSL signals are present. It is
measured in dBm/Hz. The QLN can be used in
analyzing crosstalk. 1
linetssi < slot-port >
Displays the VDSL line’s TSSI parameters. 1
vdsl2 band < slot-port >
Displays the status of upstream bands 0, 1, 2, 3, 4
(U0, U1, U2, U3, U4) and downstream bands 1, 2,
3, 4 (D1, D2, D3, D4) for the VDSL2 line connected
to the specified port. 1
bitalloc < slot-port >
Displays the number of bits allocated to each tone
for the VDSL2 line (connected to the specified port).
The more bits allocated, the higher the data
transmission rate.
1
chan < slot-port >
Displays VDSL2 statistics for a specified port since
the port’s link last came up. 1
hlog < slot-port >
Displays the Hlog parameter for the VDSL2 line
(connected to the specified port).
Hlog is one parameter of the Channel Transfer
Function in mathematics. The Hlog can be used to
see a line’s capability against interference and
attenuation.
