Configuring a Synchronous WAN Port 6-11
Configuring WAN Port Settings
To apply an input filter to a synchronous port, use the following command:
Command> set W1 ifilter [Filtername]
To apply an output filter to a synchronous port, use the following command:
Command> set W1 ofilter [Filtername]
You can remove filters from the port by entering the command without a filter name. If
a filter is changed, you must reset the port for the change to take effect.
For example, to remove the output filter from a synchronous port, use the following
commands:
Command> set W1 ofilter
Command> reset W1
Command> save all
Note – You must reset the port and re-establish the connection for the new settings to
take effect.
Setting Compression
You can set Van Jacobson TCP/IP header compression and/or Stac LZS data compression
on the port. To set compression, use the following command:
Command> set compression on|off|stac|vj
Van Jacobson TCP/IP header compression and Stac LZS data compression improve
performance on asynchronous lines but can degrade performance on high-speed
synchronous lines.
