Discussion
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.
Fix Text
Assign all disabled ports to an unused VLAN. Do not use VLAN1.
Check Content
Review the device configuration to determine if all disabled ports have been placed into an unused VLAN. The VLAN must not be VLAN 1. If disabled ports are not assigned to an unused VLAN or have been placed into VLAN 1, this is a finding.
