Check Point CCVS: Virtual System Troubleshooting and Operations

Troubleshooting and Operations tests whether you can isolate a fault to the platform, a VS, a Virtual Router, or a policy layer-and operate VSX without disrupting other tenants.

A disciplined isolation sequence

• Identify the VSID and confirm the VS is up. Use VSX status commands such as vsx stat -v; a down VS points to provisioning, memory, or platform issues, not a bad rule.
• Check the assigned interfaces and link state. A VLAN missing from the trunk or a disabled interface will look like a policy drop from inside the VS.
• Check the Virtual Router when traffic crosses VS boundaries or leaves through a shared path. Each VS has its own routing table; the VR has its own as well.
• Check policy and NAT inside the correct VS. NAT rules are per VS, so a missing hide-NAT rule is a common “no internet” cause.
• Check cluster state and sync. A failover affects every VS on the cluster, so verify whether the fault moved with the member.
• Read the VS log, not only the gateway log, and use packet captures or fw monitor in the relevant context.

Worked example

Users on VS 4 report no internet access. Confirm VS 4 is up. Check its external VLAN interface and link. Inspect the Virtual Router’s default route and the VS 4 routing table. Then inspect VS 4 policy for the outbound allow rule and hide-NAT rule. If the log shows drops on VS 4, fix the rule; if no log appears, investigate interface, ARP, or VR routing first.

Traps that cost marks

• Running diagnostics only on the gateway context and concluding the VS is healthy.
• Assuming VSs share a routing table; they do not.
• Forgetting that NAT is configured per VS.
• Blaming policy when the VLAN is absent from the trunk.
• Overlooking cluster failover because one VS recovered while others did not.
• Changing provisioning or memory during production without checking the impact on all VSs.
