-
The Cisco P switch must be configured to enforce a Quality-of-Service (QoS) policy to provide preferred treatment for mission-critical applications.
<VulnDiscussion>Different applications have unique requirements and toleration levels for delay, jitter, bandwidth, packet loss, and availabi...Rule Low Severity -

The Cisco switch must be configured to enforce a Quality-of-Service (QoS) policy to limit the effects of packet flooding denial-of-service (DoS) attacks.
<VulnDiscussion>DoS is a condition when a resource is not available for legitimate users. Packet flooding distributed denial-of-service (DDoS...Rule Medium Severity -

<GroupDescription></GroupDescription>Group -
The Cisco multicast switch must be configured to disable Protocol Independent Multicast (PIM) on all interfaces that are not required to support multicast routing.
<VulnDiscussion>If multicast traffic is forwarded beyond the intended boundary, it is possible that it can be intercepted by unauthorized or ...Rule Medium Severity -

<GroupDescription></GroupDescription>Group -
The Cisco multicast Designated switch (DR) must be configured to filter the Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) Report messages to allow hosts to join a multicast group only from sources that have been approved by the organization.
<VulnDiscussion>Real-time multicast traffic can entail multiple large flows of data. Large unicast flows tend to be fairly isolated (i.e., so...Rule Medium Severity -
The Cisco multicast edge switch must be configured to establish boundaries for administratively scoped multicast traffic.
<VulnDiscussion>If multicast traffic is forwarded beyond the intended boundary, it is possible that it can be intercepted by unauthorized or ...Rule Low Severity -
SRG-NET-000362-RTR-000120
<GroupDescription></GroupDescription>Group -
The Cisco multicast Rendezvous Point (RP) switch must be configured to limit the multicast forwarding cache so that its resources are not saturated by managing an overwhelming number of Protocol Independent Multicast (PIM) and Multicast Source Discovery Protocol (MSDP) source-active entries.
<VulnDiscussion>MSDP peering between networks enables sharing of multicast source information. Enclaves with an existing multicast topology u...Rule Low 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.
