SRG-NET-000512
<GroupDescription></GroupDescription>Group -
The SDN controller must be configured to be deployed as a cluster and on separate physical hosts.
<VulnDiscussion>SDN relies heavily on control messages between a controller and the forwarding devices for network convergence. The controlle...Rule Medium Severity -
SRG-NET-000512
<GroupDescription></GroupDescription>Group -
The SDN Controller must be configured to notify the forwarding device to either drop the packet or make an entry in the flow table for a received packet that does not match any flow table entries.
<VulnDiscussion>Reactive flow setup occurs when the SDN-aware switch receives a packet that does not match the flow table entries and hence t...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.
