SRG-NET-000512-L2S-000002
Group -
The Dell OS10 Switch must have IGMP or MLD Snooping configured on all VLANs
IGMP and MLD snooping provides a way to constrain multicast traffic at Layer 2. By monitoring the IGMP or MLD membership reports sent by hosts within a VLAN, the snooping application can set up Lay...Rule Low Severity -
SRG-NET-000512-L2S-000003
Group -
The Dell OS10 Switch must implement Rapid Spanning Tree Protocol (STP) where VLANs span multiple switches with redundant links.
STP is implemented on bridges and switches to prevent Layer 2 loops when a broadcast domain spans multiple bridges and switches and when redundant links are provisioned to provide high availability...Rule Medium Severity -
SRG-NET-000512-L2S-000004
Group -
The Dell OS10 Switch must enable Far-End Failure Detection (FEFD) to protect against one-way connections.
In topologies where fiber-optic interconnections are used, physical misconnections can occur that allow a link to appear to be up when there is a mismatched set of transmit/receive pairs. When such...Rule Medium Severity -
SRG-NET-000512-L2S-000007
Group -
The Dell OS10 Switch must have all disabled switch ports assigned to an unused VLAN.
It is possible that a disabled port that is assigned to a user or management VLAN becomes enabled by accident or by an attacker and as a result gains access to that VLAN as a member.Rule Medium Severity -
SRG-NET-000512-L2S-000008
Group -
The Dell OS10 Switch must not have the default VLAN assigned to any host-facing switch ports.
In a VLAN-based network, switches use the default VLAN (i.e., VLAN 1) for in-band management and to communicate with other networking devices using Spanning-Tree Protocol (STP), Dynamic Trunking Pr...Rule Medium Severity -
SRG-NET-000512-L2S-000009
Group -
The Dell OS10 Switch must have the default VLAN pruned from all trunk ports that do not require it.
The default VLAN (i.e., VLAN 1) is a special VLAN used for control plane traffic such as Spanning-Tree Protocol (STP), Dynamic Trunking Protocol (DTP), VLAN Trunking Protocol (VTP), and Port Aggreg...Rule Medium Severity -
SRG-NET-000512-L2S-000010
Group -
The Dell OS10 Switch must not use the default VLAN for management traffic.
Switches use the default VLAN (i.e., VLAN 1) for in-band management and to communicate with directly connected switches using Spanning-Tree Protocol (STP), Dynamic Trunking Protocol (DTP), VLAN Tru...Rule Medium Severity -
SRG-NET-000512-L2S-000011
Group -
The Dell OS10 Switch must have all user-facing or untrusted ports configured as access switch ports.
Double encapsulation can be initiated by an attacker who has access to a switch port belonging to the native VLAN of the trunk port. Knowing the victim's MAC address and with the victim attached to...Rule Medium Severity -
SRG-NET-000512-L2S-000013
Group -
The Dell OS10 Switch must not have any switch ports assigned to the native VLAN.
Double encapsulation can be initiated by an attacker who has access to a switch port belonging to the native VLAN of the trunk port. Knowing the victim’s MAC address and with the victim attached to...Rule Low Severity -
SRG-NET-000715-L2S-000120
Group -
The Dell OS10 Switch must implement physically or logically separate subnetworks to isolate organization-defined critical system components and functions.
Separating critical system components and functions from other noncritical system components and functions through separate subnetworks may be necessary to reduce susceptibility to a catastrophic o...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.
