Configuration Tasks
Use to configure the size of the CRC.
Specify the number of bits per frame (16 or 32) that are used to calculate the
frame check sequence (FCS). Both the sender and receiver must use the same
setting.
The CRC is an error-checking technique that uses a calculated numeric value to
detect errors in transmitted data.
A 32-bit CRC should be used to protect longer streams at faster rates and,
therefore, provide better ongoing error detection.
Example
host1(config-if)#crc 32
Use the no version to restore the default value, 16.
See crc.
Use to configure the HDLC idle character.
The idle character is sent between HDLC packets.
Specify one of the following idle characters:
flags—Sets the idle character to 0x7E
marks Sets the idle character to 0xFF
Example
host1(config-if)#idle-character marks
Use the no version to restore the default value, 0x7E (flags).
See idle-character.
Use to configure a serial interface in the slot/port format.
slot Number of the slot in which the line module resides in the chassis
port Number of the port on the I/O module
Example
host1(config)#interface serial 3/0
Use the no version to disable the interface.
See interface serial.
Use to enable data stream inversion for the interface.
Enable data stream inversion only if it is turned on at the other end of the line.
