g-tx rates

Indicates the transmit rates for the 802.11b802.11b is a WLAN standard often called Wi-Fi and is backward compatible with 802.11. Instead of the Phase-Shift Keying (PSK) modulation method used in 802.11 standards, 802.11b uses Complementary Code Keying (CCK) that allows higher data speeds and makes it less susceptible to multipath-propagation interference. 802.11b operates in the 2.4 GHz band and the maximum data transfer rate is 11 Mbps. or 802.11g802.11g offers transmission over relatively short distances at up to 54 Mbps, compared with the 11 Mbps theoretical maximum of 802.11b standard. 802.11g employs Orthogonal Frequency Division Multiplexing (OFDM), the modulation scheme used in 802.11a, to obtain higher data speed. Computers or terminals set up for 802.11g can fall back to speed of 11 Mbps, so that 802.11b and 802.11g devices can be compatible within a single network. radio.

The AP attempts to use the highest transmission rate to establish a mesh link. If a rate is unavailable, the AP goes through the list and uses the next highest rate.

Indicates the minimal RSSIReceived 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. If the RSSIReceived 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 a link whose average RSSIReceived 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 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).

The supported threshold is hardware dependent, with a practical range of 10–90.

HTHigh Throughput. IEEE 802.11n is an HT WLAN standard that aims to achieve physical data rates of close to 600 Mbps on the 2.4 GHz and 5 GHz bands. SSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network. Profile for the mesh feature.

 

default

mesh-mcast-opt

Enables or disables scanning of all active stations currently associated to a mesh point to select the lowest transmission rate based on the slowest connected mesh child.

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.

Best practices are to use the default value.

 

enabled

mesh-survivability

Allow mesh points and portals to become active even if the Mobility Master cannot be reached by bridging LANLocal Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. traffic. This is a beta feature that is disabled by default; it should not be enabled unless you are instructed to do so by Aruba technical suppport.

distributed-
tree-
rssi

metric-algorithm

Specifies the algorithm used by a mesh node to select its parent.

Best practices are to use the default value distributed-tree-rssi.

distributed-
tree-
rssi

best-link-rssi

Selects the parent with the strongest RSSIReceived 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-RSSIReceived 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.

mpv <mpv>

This parameter is experimental and reserved for future use.

0–4094

0 (disabled)

no

Negates any configured parameter.

reselection-mode

Specifies the method used to find a better mesh link.

Best practices are to use the default value startup-subthreshold.

(see below)

startup-sub
threshold

reselect-anytime

Mesh points using the reselect-anytime reselection mode perform a single topology readjustment scan within 9 minutes of startup and 4 minutes after a link is formed. If no better parent is found, the mesh point returns to its original parent. This initial scan evaluates more distant mesh points before closer mesh points, and incurs a dropout of 5-8 seconds for each mesh point.

After the initial startup scan is completed, connected mesh nodes evaluate mesh links every 30 seconds. If a mesh node finds a better uplink, the mesh node connects to the new parent to create an improved path to the mesh portal.

reselect-never

Connected mesh nodes do not evaluate other mesh links to create an improved path to the mesh portal.

startup-subthreshold

Mesh points using the startup-subthreshold reselection mode perform a single topology readjustment scan within 9 minutes of startup and 4 minutes after a link is formed. If no better parent is found, the mesh point returns to its original parent. This initial startup scan evaluates more distant mesh points before closer mesh points, and incurs a dropout of 5–8 seconds for each mesh point.

After that time, each mesh node evaluates alternative links if the existing uplink falls below the configured threshold level (the link becomes a sub-threshold link). Best practices are to use the default startup-subthreshold value.

If a mesh point using the startup-subthreshold mode reselects a more distant parent because its original, closer parent falls below the acceptable threshold, then as long as that mesh point is connected to that more distant parent, it will seek to reselect a parent at the earlier distance (or less) with good link quality.

For example, if a mesh point disconnects from a mesh parent 2 hops away and subsequently reconnects to a mesh parent 3 hops away, then the mesh point will continue to seek a connection to a mesh parent with both an acceptable link quality and a distance of two hops or less, even if the more distant parent also has an acceptable link quality.

subthreshold-only

Connected mesh nodes evaluate alternative links only if the existing uplink becomes a sub-threshold link.

rts-threshold

<rts-threshold>

Defines the packet size sent by mesh nodes. Mesh nodes transmitting frames larger than this threshold must issue RTSRequest to Send. RTS refers to the data transmission and protection mechanism used by the 802.11 wireless networking protocol to prevent frame collision occurrences. See CTS. and wait for other mesh nodes to respond with CTSClear to Send. 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.

Usage Guidelines

Mesh radio profiles are specific to mesh nodes (APs configured for mesh) and determine the RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. or channel used by mesh nodes to establish mesh links and the path to the mesh portal. You can configure multiple radio profiles; however, you select and deploy only one radio profile per mesh cluster.

Radio profiles, including the “default” profile, are not active until you provision your APs for mesh. If you modify a currently provisioned and running radio profile, your changes take place immediately. You do not reboot the Mobility Master or the AP.

Example

The following command creates a mesh radio profile named “radio2” and associates a mesh HTHigh Throughput. IEEE 802.11n is an HT WLAN standard that aims to achieve physical data rates of close to 600 Mbps on the 2.4 GHz and 5 GHz bands. profile named meshHT1:

(host) [mynode] (config) #ap mesh-radio-profile radio2

(host) [mynode] (Mesh Radio profile "radio2") #mesh-ht-ssid-profile meshHT1
