Global QoS Settings
Global QoS parameters configure settings that determine call quality on a global level. These settings allow you to fine tune Call Admission Control (CAC), client load balancing, bandwidth scaling, and time-to-live settings.
You can configure the following global quality-of-service parameters:
TABLE 27: Global Quality-of-Service Parameters
Command | Purpose |
qosvars admission { admitall | pending | reject } | Admission control. Valid values are admitall, pending, and reject. |
qosvars ttl ttl-value | Default time-to-live in seconds for all other protocols besides TCP and UDP. |
qosvars tcpttl ttl-value | Time-to-live for TCP protocol, in seconds. |
qosvars udpttl ttl-value | Time-to-live for UDP protocol, in seconds. |
qosvars bwscaling value | Scale factor for Tspec bandwidth, in percent. May range from 1% to as high as 100% ; 100% is typical |
qosvars cac-deauth {on | off} | Configures the optional 802.11 de-authentication behavior. |
qosvars calls-per-ap max | Configures the maximum number of calls per AP. |
qosvars calls-per-bssid max | Configures the maximum number of calls per BSSID. |
qosvars drop-policy {head|tail} | Configures the drop policy. Valid values are head or tail respectively. |
qosvars load-balance overflow {on | off} | Enables and disables load balancing across BSSIDs. |
qosvars max-stations-per-radio max | Configures the maximum stations (0-128) allowed to associate with a single radio. 128 is the default.
Recommendation: • 14 voice clients per radio for all AP models • 40 data clients per radio for all AP models except AP122, and 20 data clients for AP122 |
qosvars max-stations-per-bssid max | Configures the maximum stations (0-1023) allowed to associate with an BSSID. |

SIP Idle Timeout | Sets the time period after which an idle SIP connection will time out. |
Station Assignment Aging Time (s) | Sets the time period after which stations will begin aging out. |
Maximum Calls Per Interference Region | Specifies the number of calls that are permitted in a given interference area. |
