CCSM Advanced Firewall Troubleshooting Practice Question
An administrator is troubleshooting a VPN tunnel that fails to establish. They suspect an issue with the IKE negotiation. Which command provides detailed debugging output for IKE negotiations on a Check Point Security Gateway?
⚠ Common exam trap
Many candidates confuse general VPN debugging with IKE-specific debugging, or assuming packet capture tools can decode IKE negotiations.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
vpn debug ikeon
vpn debug ikeon is the dedicated command to enable IKE debugging, capturing detailed negotiation messages. It writes to a log file that can be examined to identify why the tunnel fails, such as mismatched proposals or authentication issues. This is the correct tool for the scenario.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
vpn debug ikeon
Why this is correct
vpn debug ikeon enables detailed IKE debugging on the gateway. It logs IKE negotiation steps to a file, typically /var/log/ike.elg, which can be analyzed to pinpoint failures in phase 1 or phase 2. This directly addresses the need for detailed IKE troubleshooting.
- ✗
fw monitor -e 'accept;'
Why it's wrong here
fw monitor captures packets but does not decode IKE negotiations or provide detailed debug information about the VPN tunnel establishment process. It would show UDP 500/4500 packets but not the IKE payload details needed to diagnose negotiation failures.
- ✗
cpstat vpn
Why it's wrong here
cpstat vpn shows statistics about VPN tunnels, such as number of active tunnels and packets encrypted, but it does not provide debugging output for IKE negotiations. It is useful for monitoring but not for troubleshooting negotiation failures.
- ✗
vpn debug on
Why it's wrong here
vpn debug on enables general VPN debugging, which includes packet-level debugging but is not specific to IKE. It may produce large amounts of data and is less focused than ikeon. For IKE-specific issues, vpn debug ikeon is more appropriate.
