672 CHAPTER 45: CPOS INTERFACE CONFIGURATION COMMANDS
Before you can configure a CPOS physical interface, you must enter its CPOS
interface view.
Example # Enter the interface view of CPOS 1/0.
<Sysname> system-view
[Sysname] controller cpos 1/0
[Sysname-Cpos1/0]
crc
Syntax crc { 16 | 32 | none }
undo crc
View Synchronizing serial interface view
Parameter 16: Sets the length of the CRC word to 16 bits.
32: Sets the length of the CRC word to 32 bits.
None: Disables CRC.
Description Use the
crc command to set the CRC word length for a synchronizing serial
interface formed by CPOS interfaces.
Use the
undo crc command to restore the default.
The CRC word length for a synchronizing serial interface formed by CPOS
interfaces defaults to 16 bits.
Example # Set the CRC word length to 16 bits for CPOS interface 1/0.
<Sysname> system-view
[Sysname] controller cpos 1/0
[Sysname-Cpos1/0] e1 3 channel-set 1 timeslot-list 1-31
[Sysname-Cpos1/0] quit
[Sysname] interface serial 1/0/3:1
[Sysname-Serial1/0/3:1] crc 16
display controller cpos
Syntax display controller cpos [ cpos-number ]
View Any view
Parameter cpos-number: CPOS interface number. If no CPOS number is specified, the
information about all CPOS interfaces is displayed.
