Passthrough and FTP acceleration

Unanswered Question
May 18th, 2010


I would like to know if active FTP is accelerated in Cisco WAAS. Active FTP uses dynamic ports therefore is not matched by the regular FTP classifier (ports 20 and 21 in source or destination)

Here's an example of an FTP session that is not accelerated.

10.x.x.x:55924   10.x.x.x:26263     MAC_address_of_peer_WAVE PT Intermediate 

And what is PT Intermediate?

Actually is there a table of all PT definitions and their detailed meaning; PT app config; PT asymm routing?



I have this problem too.

Hi Patrick,

We do not currently detect the ports used for active mode FTP.  To classify this traffic will require you to create policies based on IP address.

The ConnType "PT Intermediate" means that the WAAS device is in between two other WAAS devices and is therefore not optimizing the connection.  For the different connection types, see the attached document.

thanks Zach for the information, this document includes what I need. Is this internal Cisco documentation because I did not find it anywhere? can i use it and refer to it?

Feel free to use the document.  We should publish it in the documentation.  I'll work on that.
