QoS Tagging
(IEEE 802.1p/q)
Definition
Activates or deactivates Class of Service
(CoS) on the adapter. CoS, as defined in
the IEEE 802.1p standard, has eight
levels of priority. The priorities are 0 to 7,
with 0 the lowest priority and 7 the
highest. Activating this feature allows the
adapter to pass a CoS level to the packets
as they are transmitted. (This feature has
no affect on received traffic.) The CoS
level inserted into transmitted packets is
controlled by the application program
running on the system.
Possible settings are:
On - Activates CoS on the adapter.
Off - Disables the feature. This is the
default setting.
Note
Allied Telesyn is not aware of any
applications developed for the
Microsoft Windows operating
system that use CoS.
Consequently, it is unlikely you
would ever need to activate this
feature.
