SUMMARY

When deleting channel group number, IXPM crashes with an error:

"500 Server Error: Should not be testing a null channel group number"

Workaround: Delete all other additional Physical Interfaces except one from the Virtual Interface. Then it doesn't
crash when removing the channel-group number. Then add back.

Ideally when "Link aggregation / LAG framing" is unticked, the port-channel config should be deleted?
