Dynamic Mode CoS overrides any Layer 2 QoS configuration in case of conflicts.
NOTE: Because dot1p-mapping marks and queues packets, the only remaining applicable QoS configuration is
rate metering. You may use Rate Shaping or Rate Policing.
Layer 2 Protocol Tunneling
Spanning tree bridge protocol data units (BPDUs) use a reserved destination MAC address called the bridge group
address, which is 01-80-C2-00-00-00.
Only spanning-tree bridges on the local area network (LAN) recognize this address and process the BPDU. When you
use VLAN stacking to connect physically separate regions of a network, BPDUs attempting to traverse the intermediate
network might be consumed and later dropped because the intermediate network itself might be using spanning tree
(shown in the following illustration).
