Welch Allyn Connex and Aruba Installation Best Practices, Radio software version 3.00.01 and later - Installation Guide - Manual (Page 8)

4 Best practices Welch Allyn Network installation - Aruba
Recommended network best practices
The best practices and configuration settings listed in the following table are specific to
this vendor, and are recommended for the best performance. Increased data packet loss
or occasional disconnects are likely if these recommendations are not followed.
Best practice Affected types Without best practice
Advanced Radio Management (ARM) Settings:
5x AOS software versions
•
Power save aware scan = enabled.
• ARM scanning for source = Welch Allyn VLAN = disabled
destination = Welch Allyn network, protocol = UDP.
6x
AOS software versions
• Power save polling (PSP) aware = enabled.
• VOIP aware = enabled
• Scan interval = 180 seconds
1
Wireless APs perform ARM scanning at the time when PSP clients
are scheduled to send data, resulting in lost data.
Bandwidth 2 7 percent proportional bandwidth allocation for
APs and Welch Allyn virtual APs/Packet-Shaping
Wireless Increased probability of dropped patient data packets on
busy wireless networks.
Client Match Disabled Wireless Increased probability of disconnects and roams in busy
regions of networks.
Firmware version Use Welch Allyn-validated versions of the
Aruba Operating System: Wireless Using a non-validated version of firmware may induce
data loss.

1. Aruba 6.2 and later: adjustable via CLI only, see rf arm-profile command.
2. The 7 percent proportional bandwidth allocation will support up to 20 connected Welch Allyn devices per AP. If no Welch Allyn devices are associated with
the AP, the bandwidth is available to other devices.
