FortiSwitch 108E Mirroring

Hi there,

I am trying to use a FortiSwitch 108E to split some traffic that is being mirrored off one of our port saturated switches. I am mirroring traffic into port 2 on the FortiSwitch and I want to mirror that traffic out pots 3-8.

The first problem I have is that when setting up the mirroring rules, I often run ac cross errors such as invalid length when using the GUI and I run into sw_mirror_failed:174 errors when trying to set up new rules in the CLI.

I vaguely recall having this issue last time I tried to setup mirrors on this switch and I remember I had to keep factory resetting the device and doing the mirror rules in bulk to try to get them to stick.

Any insight into any of this? Is there a maximum amount of mirror rules that the switch can have? Thanks!
