5.4.5.4.5 Overriding a Quality of Service (QoS) Configuration
Overriding the Network Configuration
QoS values are required to provide service priority to packets. For example, VoIP packets get higher priority than data packets
to provide a better quality of service for high priority voice traffic.
The profile QoS screen maps the 6-bit Differentiated Service Code Point (DSCP) code points to the older 3-bit IP Precedent field
located in the Type of Service byte of an IP header. DSCP is a protocol for specifying and controlling network traffic by class so
that certain traffic types get precedence. DSCP specifies a specific per-hop behavior that is applied to a packet. This QoS
assignment can be overridden as needed, but removes the device configuration from the managed profile that may be shared
with other similar access point models.
To define an QoS configuration for DSCP mappings:
1. Select Devices from the Configuration tab.
2. Select Device Overrides from the Device menu to expand it into sub menu options.
3. Select a target device from the device browser in the lower, left-hand, side of the UI.
4. Select Network to expand its sub menu options.
5. Select Quality of Service .
Maximum Response Time Specify the maximum time (from 1 - 25 seconds) before sending a responding report.
When no reports are received from a radio, radio information is removed from the IGMP
snooping table. The access point only forwards multicast packets to radios present in the
snooping table. For IGMP reports from wired ports, the controller forwards these reports
to the multicast router ports. The default setting is 10 seconds.
Other Querier Time Expiry Specify an interval in either Seconds (60 - 300) or Minutes (1 - 5) to set a timeout interval
for other querier resources. The default setting is 1 minute.
NOTE: A blue override icon (to the left of a parameter) defines the parameter as having
an override applied. To remove an override, go to the Basic Configuration screen’s
Device Overrides field and select Clear Overrides . This will remove all overrides
from the device.
