5. VLAN Ethernet port Configuration
1.) Flat network
2.) Trunk and Flat
3.) Flat and Trunk
4.) Trunk and Trunk
Eth1 = AP discovery (L2)
Eth2 = RON (L3)

6. Ethernet port Configuration
A user cannot send a L3 ICMP ping between ports 1 and 2 on the wire….
…but can do so over the wireless!

15. 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.
