l If you configure more than one mesh node in the same VLAN, prevent network loops by enabling STP on the
Layer-2 switch used to connect the mesh nodes.
l Mesh nodes learn a maximum of 1024 source MAC addresses; this cannot be changed.
l Place all APs for a specific mesh cluster in the same AP group.
l Create and keep separate mesh cluster profiles for specific mesh clusters. Do not overwrite or delete the cluster
profiles.
l Enable bridging on mesh point Ethernet ports when deploying LAN bridging solutions.
l APs configured as mesh points support secure jack operation on enet0. APs with multiple Ethernet ports
configured as mesh
portals
support secure jack operation on enet1. If an AP with multiple Ethernet ports is
configured as a mesh
point
, it supports secure jack operation on enet1 and enet0.
l Mesh networks forward tagged/untagged VLAN traffic, but do not tag traffic. The allowed VLANS are controlled
by the wired ap profile.
l Mesh APs provisioned on different Dell controllers can interoperate if those APs are configured with the same
country code, cluster name and cluster key. Note, however, that the mesh recovery profile created on one
controller is not able to recover settings for mesh APs provisioned on another controller unless the recovery profile
is on a master controller and the other mesh nodes were provisioned by a local controller connected to that
master.
Post-Deployment Considerations
l Do not connect mesh point Ethernet ports in such a way that causes a network loop.
l Have a trained professional install the AP. After installation, check to ensure the AP receives power and boots up,
enabling RSSI outputs.
NOTE: Although the APus up and operational, it is not connected to the network.
l Align the AP antenna for optimal RSSI.
l Do not delete or modify mesh cluster profiles once you use them to provision mesh nodes. You can recover the
mesh point if the original cluster profile is still available. Dell recommends creating a new mesh cluster profile if
needed.
l If you create a new mesh cluster profile for an existing deployment, you must re-provision the AP for the new
profile to take effect. If you re-provision mesh nodes that are already operating, re-provision the most distant
(highest hop count) mesh points first followed by the mesh portals. If you re-provision the mesh portal first, the
mesh points may be unable to form a mesh link. Note that re-provisioning the AP causes it to automatically
reboot, which may cause a disruption of service to the network.
Dual-Port AP Considerations
The W-AP130 Series and W-AP120 Series models have The AP-12x model has two 10/100 Mbps Ethernet ports
(enet0 and enet1, respectively). When using these APs in a mesh environment, note the following Ethernet port
requirements:
l If configured as a mesh portal:
n Connect enet0 to the controller to obtain an IP address. The wired AP profile controls enet1.
n Only enet1 supports secure jack operation.
l If configured as a mesh point, enet0 and enet1 can be configured using separate wired-port-profiles. However, the
wired-ap-profile for enet0 is also applied to enet1.
