The Juniper EX switch must be configured to prune the default VLAN from all trunked interfaces that do not require it.
Medium Severity
<VulnDiscussion>All unassigned interfaces are placed into the default VLAN and devices connected to enabled, but unassigned interfaces can communicate within that VLAN. Although the default VLAN is not automatically assigned to any trunked interface, if the default VLAN must be trunked or a misconfigured trunk unintentionally includes the default VLAN, unauthorized devices connected to enabled but unassigned access interfaces could gain network connectivity beyond the local switch.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
