Juniper JUNOSE 11.2.X MULTICAST ROUTING, Configuration Manual

Page: 79 / 256

•
Example
host1(config-controll)# scramble
•
Use the no version to turn off cell scrambling on the interface.
•
If you issue the no version, be sure to issue the no dsu mode and no dsu bandwidth
commands. Otherwise, the interface might drop packets unexpectedly.
•
See scramble.
Configuring an HDLC Channel
You must configure an HDLC channel for each T3 frame or E3 frame controller.
To configure an HDLC channel, configure a serial interface (for example, HDLC channel
in slot 0, 1).
host1(config)# interface serial 0/1
Optional Tasks
The following configuration tasks are optional when you configure an HDLC channel on
a T3/E3 frame interface:
•
Configure the cyclic redundancy check (CRC).
• Configure the HDLC idle character.
• Enable data inversion on the interface.
•
Set the time interval for monitoring bit and packet rates.
•
Set the maximum receive unit (MRU).
• Set the maximum transmit unit (MTU).
• Assign a text description or an alias to the serial interface.
crc
•
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.
