Cisco’s 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 Cisco’s “VLAN in a box” wired design. Must have supporting ethernet equipment to take advantage of AP feature sets.
