| Description | This article describes a scenario where a FortiGate Virtual Machine stops passing traffic when the Number of VDOMS created exceeds the maximum number of licensed VDOM. |
| Scope | FortiGate VM v7.2+. |
| Solution |
Ensure that the VM has a VALID License by running the command 'get system status'.
get system status
... System time: Thu Sep 25 10:14:39 2025
Ensure that the VDOM license has not expired:
config global diagnose debug vm-print-license SerialNumber: FGVMSLTMxxxxxxxx
The output above shows that the FortiGate has a permanent license for 2 VDOM's and a Subscription license that allows 5 additional VDOM. However, the VDOM subscription is expired. With this configuration, the FortiGate only allows 2 VDOMs. If a third VDOM is created, all VDOMS except for the Root will be disabled.
The command 'diagnose sys vd list | grep name' will display the status of the VDOMS.
FG-LABVM-01 (global) # diagnose sys vd list | grep name name=VDOM2/VDOM2 index=2 disabled fib_ver=47 rpdb_ver=1 use=12 rt_num=0 asym_rt=0 sip_helper=0, sip_nat_trace=1, mc_fwd=0, mc_ttl_nc=0, tpmc_sk_pl=0 name=VDOM3/VDOM3 index=1 disabled fib_ver=11 rpdb_ver=0 use=8 rt_num=0 asym_rt=0 sip_helper=0, sip_nat_trace=1, mc_fwd=0, mc_ttl_nc=0, tpmc_sk_pl=0
To restore connectivity, delete the additional VDOMs or apply a VDOM license or VDOM subscription to the FortiGate.
