Load Balancing Passive Mode FTP Traffic with Data Channel Optimization
Overview: FTP passive mode load balancing with data channel optimization
You can set up the BIG-IP system to load balance passive mode FTP traffic, with optimization of both the FTP control channel and the data channel.
By default, the BIG-IP system optimizes FTP traffic for the control channel, according to the configuration settings in the default client and server TCP profiles assigned to the virtual server. When you use this particular implementation, you also configure the system to take advantage of those same TCP profile settings for the FTP data channel. This provides useful optimization of the data channel payload.
Task Summary for load balancing passive mode FTP traffic
You can perform these tasks to configure FTP passive mode load balancing that optimizes traffic on both the control channel and data channel.
Task list
Creating a custom FTP profile
Creating a custom FTP monitor
Create a custom FTP monitor to verify passive mode File Transfer Protocol (FTP) traffic. The monitor attempts to download a specified file to the /var/tmp directory. If the file is retrieved, the check is successful.
Creating a pool to manage FTP traffic
Creating a virtual server for FTP traffic
Implementation result
A BIG-IP system with this configuration can process FTP traffic in passive mode, in a way that optimizes the traffic on both the control channel and the data channel. This optimization is based on the settings of the default client-side and server-side TCP profiles.
