  • 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...
