Question about Load Balance SFTP service by using CSS1150X

Answered Question
Jan 17th, 2008

Does anyone come across of load balancing SFTP service by using CSS1150X? Typically by configuring CSS1150X to load balance FTP service, the configuration will as follow:

content ftp_rule

vip address 192.168.3.6

protocol tcp

port 21

application ftp-control

add service serv1

add service serv2

add service serv3

active

group ftp_group

vip address 192.168.3.6

add service serv1

add service serv2

add service serv3

active

However, for my personal understanding and knowledge, I will configure my CSS1150X as follow to load balance SFTP service:

content sftp_rule

vip address 192.168.3.6

protocol tcp

port 22 //Change 21 to 22

application ftp-control

add service serv1

add service serv2

add service serv3

active

group sftp_group

vip address 192.168.3.6

add service serv1

add service serv2

add service serv3

active

My question is, "application ftp-control" in content "ftp_rule" is still applicable to SFTP or not?

I have this problem too.

I believe application ftp-control would not be used for sftp.

This might cause the session to get dropped when there is no data channel created and cause issues with long connections.

Hope it helps!!
