scrambling-payload

scrambling-payload

Syntax Description

Defaults

To improve data reliability, randomize the ATM cell payload frames. This avoids continuous non-variable bit patterns and improves the efficiency of the ATM’s cell delineation algorithms. To do this, use the scrambling-payloadcommand in interface configuration mode. The no form disables scrambling.

scrambling-payload

This command has no arguments or keywords.

By default, payload scrambling is on for E1 links and off for T1 1inks.

Command Modes

Command History

Interface configuration

Release	Modification
12.0(5)XE	This command was introduced.
12.4(4)MR	This command was incorporated.

Usage Guidelines Normally, you do not issue the scrambling-payload command explicitly, because the default value is sufficient. On T1 links, the default B8ZS line encoding normally assures sufficient reliability. The scrambling setting must match that of the far end.

Examples The following example shows scrambling-payload on ATM configuration:

Router(config)# interface ATM0/0/0

Router(config-if)# no ip address

Router(config-if)#no atm ilmi-keepalive

Router(config-if)# ima-group 0

Router(config-if)# scrambling-payload
