VoIP User Profile
1.Click HiveAP Configuration > User Profiles > (Add button).
The New User Profile dialog box appears.
2.On the Generalpage, enter the following:
• User Profile Name: VoIP (You cannot include any spaces when defining a user profile name.)
• User Profile ID: 2
Each user profile must have a unique ID number. When using a local authentication mechanism, this ID links
the user profile to a subinterface (or to the SSID that gets assigned to that subinterface) so that the HiveAP
applies the QoS settings for the user profile to all traffic using that SSID/subinterface. When using a remote
RADIUS authentication scheme for IEEE 802.1X authentication, you must configure the user profile ID as an
attribute on the RADIUS server, as explained in "Configure RADIUS server attributes" on page86.
• Comment: QoS for the VoIP traffic
3.Click the QoS tab, enter the following, and then click OK:
• Entire User Profile Rate Limit: 1600 Kbps
This is the maximum amount of bandwidth that all users belonging to this profile can use. The typical
bandwidth consumption for VoIP is between 8 and 64 Kbps depending on the speech codec used. This setting
supports up to 25 concurrent VoIP sessions using 64-Kbps compression (1600 Kbps / 64 Kbps = 25 sessions).
• Entire User Profile Weight: 60
The weight defines a preference for forwarding traffic. It does not specify a percentage or an amount. Its
value is relative to other weights. However, you can see an automatically calculated percentage of this
weight versus those of other user profiles by clicking View next to Existing User Profile Weight Percentages.
Because you want HiveAPs to favor VoIP traffic over all other types, you give this profile a higher weight.
• Per User Rate Limit: 64 Kbps
This is the maximum amount of bandwidth that a single user belonging to this profile can use. It supports
from 1 to 8 concurrent VoIP sessions, depending on the voice codec used.
• Per User Queue Management: Enter the following items in bold.
You set the rate limits for Aerohive classes 0 – 5 at 56 Kbps to ensure that—even if the VoIP phone is
updating its software or is otherwise engaged in activity other than voice traffic—some bandwidth remains
reserved for voice.

Note: The default rate limit for Aerohive class 5 (voice) is 512 Kbps, which is large enough to support
conference calls, but for typical one-to-one communications, 64 Kbps is sufficient.
