Sophos XG: Red interface could not be deleted

Issue:

User configured red interface and he is trying to delete the red interface, but he was getting this below error “interface could not be deleted”

Red interface error
Interface error

Resolution:

First make sure that red interface is not associated to any DHCP server or static routing. If the interface is listed in any of the above, then you must remove the interface from both.

Otherwise type this command and check the red interface is listed in this table “XG210_WP02_SFOS 17.5.15 MR-15# psql -U nobody -d corporate -c “select * from tblinterface;””

If you observe interface is listed here, then the issue normally because of some service broke in firewall.

You can perform normal reboot and issue should be resolved.

Hope this article helps you.
