The switch requires that the VLAN/I-SID mapping is unique per port per switch, therefore only one AP
per switch port is allowed.
ExtremeWireless APs connected to a Fabric-enabled switch automatically use the default management
VLAN that is configured on the switch. Moving an AP from a Fabric-enabled switch to a non Fabric-
enabled switch requires a factory default reset to connect to the new management VLAN.
Note
In a mobility scenario that includes a local and foreign Extreme Campus Controller, make sure
the Fabric Attach topology configuration is the same on each Extreme Campus Controller,
ensuring that an AP that moves between appliances has the same set of topologies.

VxLAN Topology
Extreme Campus Controller leverage VxLAN capabilities of ExtremeXOS switches to establish dierent
head-ends for tunneling trac in an enterprise. Support includes:
Tunnel in VxLAN from AP directly to a target switch
Bypass Extreme Campus Controller
Abstracts interconnections.
VxLAN is a Layer 2 overlay scheme over a Layer 3 network. Overlays are called VxLAN segments and
only a VM and a physical machine (tenant) within the same segment have Layer 2 connectivity. VxLAN
segments are uniquely identified using an identifier called the VxLAN Network Identifier (VNI). The VNI
is a 24-bit identifier; therefore, an administrative domain can support up to 16 million overlay networks.
Because the scope of the MAC, originated by tenants, is restricted by the VNI, overlapping MAC
addresses across segments can be supported without trac leaking between tenant segments. When a
tenant frame traverses a VxLAN overlay network, it is encapsulated by a VxLAN header that contains
the VNI. This frame is further encapsulated in a UDP header and L2/L3 headers.
