scrambling-payload
scrambling-payload
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-payload command in interface configuration mode. The no form disables
scrambling.
scrambling-payload
Syntax Description This command has no arguments or keywords.
Defaults By default, payload scrambling is on for E1 links and off for T1 1inks.
Command Modes Interface configuration
Command History
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
