Managing Mesh Radio Profiles in the WebUI

Use the following procedures to define and manage mesh radio profiles using the WebUI:

• Creating or Editing a Mesh Radio Profile
• Assigning a Mesh Radio Profile to an AP Group

Creating or Editing a Mesh Radio Profile

The following procedure describes how to create or edit an existing mesh radio profile:

1. In the Mobility Conductor node hierarchy, navigate to the Configuration > System > Profiles tab.
2. Under the All Profiles pane, expand Mesh and select Mesh Radio.
3. Perform one of the following steps to create a new mesh radio profile or edit an existing profile:
   • To create a new mesh profile, click + in the Mesh Radio Profile: New Profile page and enter the profile name.
   • To edit an existing mesh profile, select the profile that you want to edit from Mesh > Mesh Radio.
4. Configure your desired mesh radio settings as described in Table 1.
5. Click Submit.
6. Click Pending Changes.
7. In the Pending Changes window, select the check box and click Deploy Changes.

   Mesh Radio profile configuration settings are divided into two tabs—General and Advanced. The General tab displays only those configuration settings that often need to be adjusted to suit a specific network. The Advanced tab shows all configuration settings, including settings that do not need frequent adjustment or should be kept at their default values. If you change a setting on one tab, then click and display the other tab without saving your configuration, that setting reverts to its previous value.

   The following table describes the basic and advanced profile settings of mesh radio profile.

If the RSSI Received Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values. value is below this threshold, the link may be considered a sub-threshold link. A sub-threshold link is one whose average RSSI Received Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values. value falls below the configured link threshold. If this occurs, the mesh node may try to find a better link on the same channel and cluster (only neighbors on the same channel are considered). Default: 12. The supported threshold is hardware dependent, with a practical range of 10–90.

   BC/MC Rate Optimization	Broadcast or Multicast Rate Optimization dynamically selects the rate for sending broadcast or multicast frames on any BSS Basic Service Set. A BSS is a set of interconnected stations that can communicate with each other. BSS can be an independent BSS or infrastructure BSS. An independent BSS is an ad hoc network that does not include APs, whereas the infrastructure BSS consists of an AP and all its associated clients. . This feature determines the optimal rate for sending broadcast and multicast frames based on the lowest of the unicast rates across all associated clients. When you enable the Multicast Rate Optimization feature, the managed node scans the list of all associated stations in that BSS Basic Service Set. A BSS is a set of interconnected stations that can communicate with each other. BSS can be an independent BSS or infrastructure BSS. An independent BSS is an ad hoc network that does not include APs, whereas the infrastructure BSS consists of an AP and all its associated clients. and finds the lowest transmission rate as indicated by the rate adaptation state for each station. If there are no associated stations in the BSS Basic Service Set. A BSS is a set of interconnected stations that can communicate with each other. BSS can be an independent BSS or infrastructure BSS. An independent BSS is an ad hoc network that does not include APs, whereas the infrastructure BSS consists of an AP and all its associated clients. , it selects the lowest configured rate as the transmission rate for broadcast and multicast frames. This feature is enabled by default. Multicast Rate Optimization applies to broadcast and multicast frames only. 802.11 802.11 is an evolving family of specifications for wireless LANs developed by a working group of the Institute of Electrical and Electronics Engineers (IEEE). 802.11 standards use the Ethernet protocol and Carrier Sense Multiple Access with collision avoidance (CSMA/CA) for path sharing. management frames are not affected by this feature and are transmitted at the lowest configured rate. When enabled, this setting dynamically adjusts the multicast rate to that of the slowest connected mesh child. Multicast frames are not sent if there are no mesh children. This feature should only be enabled on a BSS Basic Service Set. A BSS is a set of interconnected stations that can communicate with each other. BSS can be an independent BSS or infrastructure BSS. An independent BSS is an ad hoc network that does not include APs, whereas the infrastructure BSS consists of an AP and all its associated clients. where all associated stations are sending or receiving unicast data. If there is no unicast data to or from a particular station, then the rate adaptation state may not accurately reflect the current sustainable transmission rate for that station. This could result in a higher packet error rate for broadcast or multicast packets at that station. Configuring the Video Multicast Rate Optimization parameter overrides the configuration of BC/MC Rate Optimization parameter for VI-tagged multicast traffic. Multicast traffic that is not VI-tagged behaves the same with BC or MC as before. If multicast rate is not set, all traffic behaves the same. Default: Enabled.

In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN.

   Metric algorithm	This parameter specifies the algorithm used by a mesh node to select its parent. Use this setting to optimize operation of the link metric algorithm. Available options are: best-link-rssi—Selects the parent with the strongest RSSI Received Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values., regardless of the number of children a potential parent has. distributed-tree-rssi—Selects the parent based on link-RSSI Received Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values. and node cost based on the number of children. This option evenly distributes the mesh points over high quality uplinks. Low quality uplinks are selected as a last resort. Default: distributed-tree-rssi. It is recommended to use the default value.

The CTS refers to the data transmission and protection mechanism used by the 802.11 wireless networking protocol to prevent frame collision occurrences. See RTS. to begin transmission. This helps prevent mid-air collisions. Default: 2333 bytes Range: 256– 2346

9. In the Pending Changes window, select the check box and click Deploy Changes.

The profile name appears in the Mesh Radio Profile list with your configured settings.

If you configure this for the AP group, this profile also becomes the selected radio profile used by the mesh portal for your mesh network.
