Cisco NX OS Switch RTR Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The Cisco PE switch providing MPLS Layer 2 Virtual Private Network (L2VPN) services must be configured to authenticate targeted Label Distribution Protocol (LDP) sessions used to exchange virtual circuit (VC) information using a FIPS-approved message authentication code algorithm.
<VulnDiscussion>LDP provides the signaling required for setting up and tearing down pseudowires (virtual circuits used to transport Layer 2 f...Rule Medium Severity -

<GroupDescription></GroupDescription>Group -
The Cisco PE switch providing MPLS Virtual Private Wire Service (VPWS) must be configured to have the appropriate virtual circuit identification (VC ID) for each attachment circuit.
<VulnDiscussion>VPWS is an L2VPN technology that provides a virtual circuit between two PE switches to forward Layer 2 frames between two cus...Rule High Severity -

<GroupDescription></GroupDescription>Group -
The Cisco PE switch providing Virtual Private LAN Services (VPLS) must be configured to have all attachment circuits defined to the virtual forwarding instance (VFI) with the globally unique VPN ID assigned for each customer VLAN.
<VulnDiscussion>VPLS defines an architecture that delivers Ethernet multipoint services over an MPLS network. Customer Layer 2 frames are for...Rule High Severity -

<GroupDescription></GroupDescription>Group -
The Cisco switch must not be configured to use IPv6 Site Local Unicast addresses.
<VulnDiscussion>As currently defined, site local addresses are ambiguous and can be present in multiple sites. The address itself does not co...Rule Medium Severity -
The Cisco PE switch must be configured to limit the number of MAC addresses it can learn for each Virtual Private LAN Services (VPLS) bridge domain.
<VulnDiscussion>VPLS defines an architecture that delivers Ethernet multipoint services over an MPLS network. Customer Layer 2 frames are for...Rule Medium Severity -

<GroupDescription></GroupDescription>Group -
The Cisco PE switch must be configured to block any traffic that is destined to the IP core infrastructure.
<VulnDiscussion>IP/MPLS networks providing VPN and transit services must provide, at the least, the same level of protection against denial-o...Rule High 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.
