when the output que size full , provided wred configured only on class-default will it impact voip traffic on the other classes
Iam asking this because recently we have a issue like this (dropping voip calls) so when we disable the wred on the class-default and increase the que siz under this class then the issue seems to be normalised
I wonder how come the udp traffic get impacted due to wred configured on the clas-default
Our Config like this
service policy ouput shaping
troubleshooting done was
queue size (increased)
wred is dropping packets based on dscp or ip precedence of packet. If every packet have the same (probably 0) dscp value, than all packets will be threated the same. Make sure that voip traffic is properly marked/threaten.
