Configuring WLAN mesh services
WLAN mesh services overview
WLAN mesh services allows an AP to provide wireless services to clients, without a wired interface on the AP. Instead
of a wired interface, there is a radio link to another AP with a wired interface.
WLAN mesh services can be used at sites, when running Ethernet cable to a location is inconvenient, expensive, or
impossible.
Multihop is now available when configuring Mesh Services. The system can support upto 16 Mesh Portals with each
Mesh Portal supporting a 6 Mesh AP fan-out with a depth of 2 Mesh APs. Also, a single AP can perform two roles:
• Mesh Portal
•Mesh AP
Mesh Services reliability is improved by adding the following :
• Improved transmission of station session record.
• Ability to manage link loss between Mesh Portals and Mesh APs.
• Improved management of duplicate messages for SSR updates from multiple Mesh APs.
Mesh portal selection has improved by scanning for Mesh Link SSIDs and sorting them by RSSI values. The Mesh AP
establishes a link using the RSSI values in descending order. If all attempts fail, the Mesh AP scans from the beginning
of the table. After 60 seconds and no link is established, the Mesh AP reboots.
If the Mesh Link is using a DFS channel, then the Mesh Link has a timeout of 140 seconds to allow for DFS channel
assessment. Mesh Portal selection is improved by scanning for Mesh Link SSIDs and sorting them by RSSI values. The
