NimbostratusSource address persistence
If i do a tmsh sh ltm persistence persist-records I just see the VIP address and the node address... I would expect to see the public source IP of the client? We do not have any nat or snat enabled. Is this normal?
Is there a way I can tell if a client IP has a persistance record on the F5 and what node it points to?
I assume that source address persistence gets refreshed as the client sends data back and forth over the load balancer? It doesn't automatically timeout x seconds after the persistence is created correct? It times out x seconds after it's been idle?

can you try "show ltm persistence persist-records all-properties"?root@ve10(Active)(tmos) show ltm persistence persist-records all-properties Sys::Persistent Connections source-address - 172.28.19.252:80 - 200.200.200.101:80 ------------------------------------------------------ TMM 0 Mode source-address Key 192.168.206.75 Age (sec.) 8 Virtual Name bar Virtual Addr 172.28.19.252:80 Node Addr 200.200.200.101:80 Pool Name foo Client Addr 192.168.206.75 Total records returned: 1 
Matt_70198Aha, I didn't see that all-properties option when I did ?... Thank Nitass!
What causes the persistence to be refreshed? I can look at my own connection an see the age time increase with time... when I click some links it doesn't reset, then I click another link and the age resets and goes back to 0.- Matt_70198
Also one more question, if there is persistence to a given node... and that node goes offline, what happens with that persistence record? Is it dropped automatically?
- nitassWhat causes the persistence to be refreshed? I can look at my own connection an see the age time increase with time... when I click some links it doesn't reset, then I click another link and the age resets and goes back to 0.it will be refreshed if bigip receives (processes) request. are you sure if that content is not from (browser or proxy) cache?
