Understanding Mesh Profiles

Mesh profiles help define and bring-up the mesh network. The following sections describe the mesh cluster, mesh radio, and mesh recovery profiles in more detail.

The complete mesh profile consists of a mesh radio profile, RF management (802.11a and 802.11g) radio profiles, a high-throughput SSID profile (if your deployment includes 802.11n-capable APs), a mesh cluster profile, and a read- only recovery profile. The recovery profile is dynamically generated by the master controller; you do not explicitly configure the recovery profile.

Dell provides a “default” version of the mesh radio, RF management, high-throughput SSID and cluster profiles with default values for most parameters. You can use the “default” version of a profile or create a new instance of a profile which you can then edit as you need. You can change the values of any parameter in a profile. You have the flexibility of applying the “default” versions of profiles in addition to customizing profiles that are necessary for the AP or AP group to function.

If you assign a profile to an individual AP, the values in the profile override the profile assigned to the AP group to which the AP belongs. The exception is the mesh cluster profile—you can apply multiple mesh cluster profiles to individual APs, as well as to AP groups.

Mesh Cluster Profile

Mesh clusters are grouped and defined by a mesh cluster profile, which provides the framework of the mesh network. Similar to virtual AP profiles, the mesh cluster profile contains the MSSID (mesh cluster name), authentication methods, security credentials, and cluster priority required for mesh nodes to associate with their neighbors and join the cluster. Associated mesh nodes store this information in flash memory. Although most mesh deployments require only a single mesh cluster profile, you can configure and apply multiple mesh cluster profiles to an AP group or an individual AP. If you have multiple cluster profiles, the mesh portal uses the profile with the highest priority to bring up the mesh network. Mesh points, in contrast, go through the list of mesh cluster profiles in order of priority to decide which profile to use to associate themselves with the network. The mesh cluster priority determines the order by which the mesh cluster profiles are used. This allows you, rather than the link metric algorithm, to explicitly segment the network by defining multiple cluster profiles.

Dell provides a “default” version of the mesh cluster profile. You can use the “default” version or create a new instance of a profile which you can then edit as you need. You can configure a maximum of 16 mesh cluster profiles on a mesh node. For details about configuring mesh cluster profiles, see “Mesh Cluster Profiles”.

Mesh Radio Profile

Dell provides a “default” version of the mesh radio profile. You can use the “default” version or create a new instance of a profile which you can then edit as you need. The mesh radio profile allows you to specify the set of rates used to transmit data on the mesh link. For information about configuring mesh radio profiles, see "Working with Mesh Radio Profiles" on page 450.

RF Management (802.11a and 802.11g) Profiles

The two 802.11a and 802.11g RF management profiles for an AP configure its 802.11a (5 Ghz) and 802.11b/g (2.4 GHz) radio settings. Use these profile settings to determine the channel, beacon period, transmit power, and ARM profile for a mesh AP’s 5 GHz and 2.5 Ghz frequency bands. You can either use the “default” version of each profile, or create a new 802.11a or 802.11g profile which you can then configure as necessary. Each RF management profile also has a radio-enableparameter that allows you to enable or disable the AP’s ability to simultaneously carry WLAN client traffic and mesh-backhaul traffic on that radio. This value is enabled by default. For information about configuring RF Management Radio profiles, see "802.11a and 802.11g RF Management Profiles" on page 424.
