Slide 15 Confidential Ciscos implementation: Standards Based
Management Interfaces Does not roam across VLANs Must rely on
software to keep roam alive Session failure. Must re-authenticate
when roaming to new VLAN. Creates STP (Spanning Tree) issues.
Defeats Ciscos VLAN in a box wired design. Must have supporting
ethernet equipment to take advantage of AP feature sets. Slide 16
