QoS (WMM) level Voice and Video

[kumara.s]

Hi,

Under QoS (WMM) level setting, I understand -
'No QoS' means WMM is disabled and all traffic treated the same;
'Auto Priority' enables WMM, uses the right WMM Access-category by classifying traffic based on already marked ToS/DSCP field in the IP header of packets entering from wired end. This differentiates services between data, video and voice.

What does 'Voice priority' and 'Video Priority' setting do?

Will greatly appreciate any info on this. Thanks in advance!

Thanks a lot. Sorry for the duplicate post.

Just to clarify a few more things...
When "Voice priority" is selected, which value (between 6 and 7) is used to mark the TOS field in IP header? Similarly which one for "video priority" (between 4 and 5)? Are the packets actually sent with these TOS values or are they just used to determine the WMM access category?

From the referred post, I understand that "Auto priority" is valid only in bridge mode. Is it true for Video and Voice priority setting too?

Thanks!

when "voice priority" is selected, does 'all' packets get to use the WMM access category for 'voice' or does it apply only for packets falling within a specific length (since smaller length can be used as a rough indicator of Voice packet).
