The ESXi host must enable Bridge Protocol Data Units (BPDU) filter on the host to prevent being locked out of physical switch ports with Portfast and BPDU Guard enabled.
<VulnDiscussion>BPDU Guard and Portfast are commonly enabled on the physical switch to which the ESXi host is directly connected to reduce th...Rule Medium Severity -

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
