1:1 SNAT to CLIENT IP
On my ltm I am running version 11.4.0 and 11.4.1 on two different chassis There is a line that is concerning with in the following link
https://devcentral.f5.com/wiki/irules.snat_pool_persistence.ashx
set static::i 0 // Which is line 15 incr static::i // Which is line 22
I am under the impression that for boxes that will run CMP or have multiples instances of TMM present and not running CMP You shouldn't alter the value of a static variable
According to the following link there is a nonte that states the following
https://support.f5.com/kb/en-us/solutions/public/13000/000/sol13033.html?sr=39629869
Important: While it is possible to use the set command to modify a static global variable within the iRule and outside of the RULE_INIT event, such modifications will not be propagated to each TMM instance; they will be visible to only the TMM process on which the modification was made, resulting in inconsistent values for the static global variable across TMM instances. As a result, F5 strongly recommends that you do not update the value of any static global variable within the iRule.
I am looking for an understanding if the first link
https://devcentral.f5.com/wiki/irules.snat_pool_persistence.ashx
set static::i 0 // Which is line 15 incr static::i // Which is line 22
Is correct incrementing the static variable "incr static::i" with out issue's
Thank You for your response in advance
