Questions About FortiADC 7.6.4 CLI Commands

Hi everyone,
I’m working with FortiADC 7.6.4 and would like to ask about a couple of CLI commands. If anyone has information, I’d appreciate your help.

 

1. Checking interface link status
    Is there a CLI command that shows the actual link status of an interface?
    According to the documentation, the command
    "get system interface"
    only provides the enabled/disabled status, so I understand it does not show the real-time link state.

 

    I also looked at the following command:

    "diagnose hardware get deviceinfo nic-detail"
    which appears to offer detailed NIC information, but it does not show the link status for aggregated (LAG) interfaces.

 

2. Deleting backup configuration files
    I know that configuration backups can be created using:
    "execute restore config disk <name>"
    However, I haven’t been able to find a CLI command that deletes configuration backup files stored on disk.
    Is there a way to remove these backup files through the CLI?

 

Thanks in advance for your support!

    AEK, thanks for your reply.


    For some reason, the command you suggested only returns a blank line with no output.


    The output looks something like this:

    FortiADC #  FortiADC # diagnose netlink interface list lag01   FortiADC #  FortiADC #  FortiADC # diagnose netlink interface list port1   FortiADC #

    https://docs.fortinet.com/document/fortiadc/7.6.4/cli-reference/188513

    try doing a ? after interface in order for the system to give you all the options and then select one. according to the link it should work/display the state/flag.

      Probably you discovered a new issue, since there is no known issue on 7.6.4 so far.

      I tested on a FAD 7.6.4 VM (on KVM).

      The command seem to work as expected.

      Here I have agg1 made of port2 (up) and port3 (down).

      We can see the status is displayed correctly as "run" (in blue) when the interface is plugged.

      fad01 # diagnose netlink interface list port2
      if=port2 family=00 type=1 index=5 mtu=1500 link=0 master=13
      flags=up broadcast run slave multicast 
      Qdisc=pfifo_fast hw_addr=52:54:00:3f:b3:fb: broadcast_addr=ff:ff:ff:ff:ff:ff:
      stat: rxp=99 txp=24 rxb=7730 txb=2424 rxe=0 txe=0 rxd=0 txd=0 mc=0 collision=0
      re: rxl=0 rxo=0 rxc=0 rxf=0 rxfi=0 rxm=0
      te: txa=0 txc=0 txfi=0 txh=0 txw=0


      fad01 # diagnose netlink interface list port3
      if=port3 family=00 type=1 index=6 mtu=1500 link=0 master=13
      flags=up broadcast slave multicast 
      Qdisc=pfifo_fast hw_addr=52:54:00:3f:b3:fb: broadcast_addr=ff:ff:ff:ff:ff:ff:
      stat: rxp=0 txp=0 rxb=0 txb=0 rxe=0 txe=0 rxd=0 txd=0 mc=0 collision=0
      re: rxl=0 rxo=0 rxc=0 rxf=0 rxfi=0 rxm=0
      te: txa=0 txc=0 txfi=0 txh=0 txw=0


      fad01 # diagnose netlink interface list agg1
      if=agg1 family=00 type=1 index=13 mtu=1500 link=0 master=0
      flags=up broadcast run master multicast vlan_id=4 vlan_flag=
      Qdisc=noqueue hw_addr=52:54:00:3f:b3:fb: broadcast_addr=ff:ff:ff:ff:ff:ff:
      stat: rxp=68 txp=22 rxb=3874 txb=2298 rxe=0 txe=0 rxd=0 txd=0 mc=0 collision=0
      re: rxl=0 rxo=0 rxc=0 rxf=0 rxfi=0 rxm=0
      te: txa=0 txc=0 txfi=0 txh=0 txw=0

      As it works fine on the VM then probably the bug is related to the hardware appliance.

      Try open a ticked.

        Thanks for raising these questions. The interface link status for LAG interfaces can definitely be tricky to verify through CLI alone

        Interesting discussion. I've also seen limitations when checking real-time link status on aggregated interfaces. 69live apk Hopefully someone from the Fortinet community can clarify the best approach for both link-state verification and backup file deletion.
