IP address

You may want to verify the IP addresses assigned to the FortiGate interfaces are what you expect them to be.

To verify IP addresses:

diagnose ip address list

The output lists the:

  • IP address and mask (if available)
  • index of the interface (a type of ID number)
  • devname (the interface name)

While physical interface names are set, virtual interface names can vary. A good way to use this command is to list all of the virtual interface names. For vsys_ha and vsys_fgfm, the IP addresses are the local host, which are virtual interfaces that are used internally.

Sample output:

# diagnose ip address list

IP=10.31.101.100->10.31.101.100/255.255.255.0 index=3 devname=internal

IP=172.20.120.122->172.20.120.122/255.255.255.0 index=5 devname=wan1

IP=127.0.0.1->127.0.0.1/255.0.0.0 index=8 devname=root

IP=127.0.0.1->127.0.0.1/255.0.0.0 index=11 devname=vsys_ha

IP=127.0.0.1->127.0.0.1/255.0.0.0 index=13 devname=vsys_fgfm
