22.4.2 Qos Troubleshooting
&
QoS is disabled on switch ports by default, 4 sending queues are set by default, queue1 forwards
normal packages, other queues are used for some important control packets (such as BPDU).
Choose an array according to the Cos value when QoS is shut down
&
When QoS is enabled in Global Mode,. QoS is enabled on all ports with 4 traffic queues. The
default CoS value of the port is 0; port is in not Trusted state by default; the default queue weight
values are 1, 2, 4, 8 in order, all QoS Map is using the default value.
&
CoS value 7 maps to queue 4 that has the highest priority and usually reserved for certain protocol
packets. It is not recommended for the user to change the mapping between CoS 7 to Queue 4, or
set the default port CoS value to 7.
&
Policy map can only be bound to ingress direction, egress is not supported yet.
&
If the policy is too complex to be configured due to hardware resource limit, error massages will be
provided.
