CSM 411 FTP issue

[fsebera]

Show mod csm 4 conn 1.1.1.1 detail

shows ftp control channel port 21 has a valid source and destination port during the INIT and ESTAB phase.

However, the DATA channel has a valid source and destination port during the INIT phase but as soon as the phase changes to ESTAB, the DATA port changes to :20 and :0. No matter the amount of data transferred, it is always :20 and :0.

Could anyone shead a little light?

Thanks

HI Frank,

depening on the ftp mode (active or passive) you are having different ports for the data connections (see http://slacksite.com/other/ftp.html)

I assume that the FTP is not working well is it?

If not give it a try with the command virtual 1.1.1.1 tcp ftp service ftp

(refer to http://www.cisco.com/en/US/products/hw/switches/ps708/products_command_reference_chapter09186a0080212b24.html#wp1060164)

Or just use a layer 3 content rule and stick the client to the real.

Kind Regards,

Joerg
