NimbostratusUsing irule to set persistence profile
We are running LTM v11.2.1 on 4200 devices.
I currently have a source address persistence profile set for all traffic going through one of my virtual servers. I have been asked to find a way to ...

NimbostratusI have a few irules invoked by different virtual servers. Sometimes the persistence will be set at vs level, and sometimes it will be set in the irule with the same non-standadrd settings. Unfortunately, there doesn't seem to be a way to call a persistence profile object from within an irule :-( If it was possible, I wouldn't have to edit the irules in case of a settings change...

NimbostratusI'm not sure if this exactly fits. I'll try exposing some samples to illustrate :
ltm persistence source-addr toto {
app-service none
defaults-from source_addr
timeout 900
}
ltm virtual A {
[...]
persist {
persist_PFCI_WHEAT_srcaddr {
default yes
}
}
pool toto
[...]
}
ltm virtual B {
[...]
rules {
toto
}
[...]
}
ltm rule toto {
when CLIENT_ACCEPTED {
if { blabla } {
persist source_addr 255.255.255.255 900
pool toto
}
[...]
}
}
The syntax for source address persitence in irule is : persist srcaddr [mask ] []
My wish here would be to write something like this in irule : persist toto
