Dynamic Mode CoS for VLAN Stacking

Dynamic Mode CoS for VLAN Stacking
One of the ways to ensure quality of service for customer VLAN-tagged frames is to use the 802.1p
priority bits in the tag to indicate the level of QoS desired. When an S-Tag is added to incoming customer
frames, the 802.1p bits on the S-Tag may be configured statically for each customer or derived from the
C-Tag using Dynamic Mode CoS. Dynamic Mode CoS maps the C-Tag 802.1p value to a S-Tag 802.1p
value.
