96 | Configuration Reference Dell PowerConnect W-AirWave 7.5 | Configuration Guide3. Select Add or Save. The added or edited Radio profile appears on the Profiles > Mesh > Radio page.Profiles > Mesh > Radio > Mesh HT SSIDThe mesh high-throughput SSID profile enables or disables high-throughput (802.11n) features for the SSIDspecified in the profile. This parameter is enabled by default. The mesh high-throughput profile can have amaximum of 32 characters.Perform these steps to configure a Mesh HT SSID profile.1. Select Profiles > Mesh > Radio > Mesh HT SSID in the Dell PowerConnect W Navigation pane. Thedetails page summarizes the current profiles of this type.2. Select the Add button to create a new Mesh HT SSID profile, or click the pencil icon next to an existing profileto edit. Complete the settings as described in Table 44:802.11g Transmit Rates All selected Indicate the transmit rates for the 802.11g radio. The AP attempts to use the highesttransmission rate to establish a mesh link. If a rate is unavailable, the AP goesthrough the list and uses the next highest rate.Mesh Private VLAN (0-4094)0 Enter a VLAN ID for control traffic between an remote mesh portal and mesh nodes.This VLAN ID must not be used for user traffic.Range: 0-4094. Default: 0 (disabled).BC/MC RateOptimizationYes Enable or disable scanning of all active stations currently associated to a meshpoint to select the lowest transmission rate based on the slowest connected meshchild.When enabled, this setting dynamically adjusts the multicast rate to that of theslowest connected mesh child. Multicast frames are not sent if there are no meshchildren.NOTE: AirWave recommends using the default value.Table 44 Mesh > Radio > Mesh HT SSID Profile SettingsField Default DescriptionGeneral SettingsFolder Top Set the folder with which the profile is associated. The drop-down menu displays allfolders available for association with the profile.Name Blank Enter the name of the profile. This profile name can have a maximum of 32 characters.Other Settings40 MHz Channel Usage Yes Enable or disable the use of 40 MHz channels. This parameter is enabled by default.Low-density ParityCheckIf enabled, the AP will advertise Low-density Parity Check (LDPC) support. LDPC improvesdata transmission over radio channels with high levels of background noise. Requires aminimum version of 6.1.0.0.MPDU Aggregation Enable or disable MAC protocol data unit (MPDU) aggregation.High-throughput mesh APs are able to send aggregated MAC protocol data units(MDPUs), which allow an AP to receive a single block acknowledgment instead of multipleACK signals. This option, which is enabled by default, reduces network traffic overhead byeffectively eliminating the need to initiate a new transfer for every MPDU.Table 43 Profiles > Mesh > Radio Profile Settings (Continued)Field Default Description
