Displaying OC12 status and nailed groups
To see the nailed-group numbers for OC12 ports, and any other ATM ports, use the
atmtrunks
command. For example, the command output that follows shows the
status and nailed-group numbers for OC12 trunks on a trunk module in slot 17, and
OC3 trunks on a trunk module in slot 18.

All DS3 ATM trunks:
DS3 Lines (dvOp dvUpSt dvRq sAdm nailg)
All E3 ATM trunks:
E3 Lines (dvOp dvUpSt dvRq sAdm nailg)
All OC12 lines:
(dvOp dvUpSt dvRq sAdm nailg)

Parameter
Specifies
rx-scrambler-type
Selects the type of algorithm used to descramble the signal
being received. Valid entries are:
■
ast-none
—The received signal has not been scrambled.
■
ast-x31
—The received signal has been scrambled using
the polynomial, X
31
+1.
■
ast-x43
(the default)—The received signal has been
scrambled using the polynomial, X
43
+1.
tx-scrambler-type
Selects the type of algorithm used to scramble the signal
being transmitted. Valid entries are:
■
ast-none
—The signal is not scrambled.
■
ast-x31
—The signal is scrambled using the
polynomial, X
31
+1.
■
ast-x43
(the default)—The signal is scrambled using
the polynomial, X
43
+1.
discard-errored-cells
Sets all HEC errored cells for discard. Valid entries are:
■
yes
(the default)—all HEC errored cells are discarded.
■
no
—all HEC errored cells are passed to the ATM layer.
