What is the name of the debug save file for IPSec VPN tunnels?

`set vpn all up` is not a debug command or a file name; it resembles a command to enable VPNs.

`test vpn ike-sa` is an operational command used to check the status of an IKE Security Association, not a debug file name.

`request vpn IPsec-sa test` is an operational command used to check the status of an IPSec Security Association, not a debug file name.

When troubleshooting IPSec VPN tunnels on a Palo Alto Networks firewall, the packet capture file that contains debugging information for the Internet Key Exchange (IKE) manager process, which is responsible for establishing and maintaining VPN security associations, is typically named `ikemgr.pcap`. This file is crucial for analyzing IKE phase 1 and phase 2 negotiation issues.
