If an administrator needs persistent connections to the virtual server during client transactions,
enter the number of seconds of inactivity allowed to lapse before a connection times out in this
text field.
Important
If you entered a value in the
Firewall Mark
field above, you should
enter a value for persistence as well. Also, be sure that if you use
firewall marks and persistence together, that the amount of persistence
is the same for each virtual server with the firewall mark. For more
on persistence and firewall marks, see Section 6.5, Persistence and
Firewall Marks.
Persistence Network Mask
To limit persistence to particular subnet, select the appropriate network mask from the drop-
down menu.
Note
Before the advent of firewall marks, persistence limited by subnet was
a crude way of bundling connections. Now, it is best to use persistence
in relation to firewall marks to achieve the same result.
