configure ppp pos scrambling ports
ExtremeWare Software 7.3.0 Command Reference Guide 1657
configure ppp pos scrambling ports
configure ppp pos scrambling [on | off] ports
<portlist>
Description
Specifies whether the payload data should be scrambled on the specified ports. RFC 2615 recommends
that the SONET payload be scrambled.
Syntax Description
Default
The default is scrambling
on
.
Usage Guidelines
The option of disabling scrambling is provided for backward compatibility with an earlier (now
obsoleted) PoS standard specified in RFC 1619. Scrambling was introduced in RFC 2615 to alleviate
potential security problems where malicious users might generate packets with bit patterns that create
SONET synchronization problems.
Example
The following command example turns off the scrambling function for port 1 of the PoS module
installed in slot 8 of the BlackDiamond switch:
config ppp pos scrambling off ports 8:1
