View Next Audit Version


A disabled port that is assigned to a user or management VLAN may become enabled by accident or by an attacker and as a result may gain access to that VLAN as a member.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.


Assign all switch ports not in use to an inactive VLAN.

Step 1: Assign the disabled interfaces to an inactive VLAN:

SW3(config)#int range g0/0 - 9
SW3(config-if-range)# switchport access vlan 999

Step 2: Configure trunk links to not allow traffic from the inactive VLAN:

SW3(config)#int g1/1
SW3(config-if)#switchport trunk allowed vlan except 999
