On an Phase 2 IPsec SA with a non-zero lifesize, I see the proposed initial lifesize in the "show vpn ipsec-sa" output,

Show IPSec SA: Total 6 tunnels found. 4 ipsec sa found.
Unlike the lifetime, the lifesize is not decrementing as data goes over the tunnel. So I have two questions,
1) Where can I find the actual lifesize remaining on a tunnel?
2) Or does PAN-OS not actually track lifesize?
Yes, it does show lifetime. I was looking for the lifesize. There is a mention of it in the flow output,
when lifetime expired:0
when lifesize expired:0
But that's not about what the current lifesize counter is at. I guess you can use the encapsulated and decapsupated byte counts to figure it out.
Agree with you. Life-size is the amount of data that the key can use for encryption and we do keep track of it being decremented so as to re-key once the lifesize limit is reached.
But just that it is not displayed unlike Life-time. Since it appears under IPsec crypto profiles, It can monitored through the ">show vpn ipsec-sa" command that you are already aware of.
I believe the only way for us to track it live would be through "encap bytes" under show vpn flow command.
Your explanation it's clear about life-size.
I have problem with a VPN Tunnel, for some reason peers involved are taking long time to re-establish it.
What does it means this one:
"lifetime 3600 Sec lifesize unlimited"
I can see this message in system logs; Can it cause issue when both peers are trying to re-negotiate VPN tunnel?
I need to configure a specific parameter for life-size?
Is that possible?
Thanks in advance
