Fix Recommendation

Best practice for VLAN-based networks is to prune unnecessary trunk links from gaining access to the default VLAN and to ensure that frames belonging to the default VLAN do not traverse trunks not requiring frames from the VLAN.

Check Contents

Review the switch configuration and verify that the default VLAN is pruned from trunk links that do not require it.

If the default VLAN is not pruned from trunk links that should not be transporting frames for the VLAN, this is a finding.
