Command History
Usage Guidelines Sticky connections are not tracked. The group ID default is 0. The sticky feature is not used for other
virtual servers. The network default is 255.255.255.255.
The last real server that was used for a connection from a client is stored for the duration value after the
end of the client’s latest connection. If a new connection from the client to the virtual server is initiated
during that time, the same real server that was used for the previous connection is chosen for the new
connection.
A nonzero sticky group ID must correspond to a sticky group previously created using the sticky
command. Virtual servers in the same sticky group share sticky state information.
duration Sticky timer duration in minutes; the range is from 1 to 65535.
group (Optional) Places the virtual server in a sticky group for connection
