You can modify only ingress and egress HQoS child policy's class-map and its actions using policy-map AVB-Output-Child-Policy and policy-map AVB-Input-Child-Policy command. You should not modify the PCP in child policy to map with PCP configured in Parent Policy, for example SR Class A Cos 3 and SR Class B Cos 2. Note Hierarchical Policing Hierarchical policing is supported on ingress and egress interfaces. Hierarchical QoS separates the SR and Non-SR class related rules into parent and child policies respectively. AVB SR classes are completely controlled by MSRP client and hence, parent policies containing SR class attributes are governed by MSRP.
The end user has complete control over child policies which contain Non-SR class attributes and can modify only the child policies. AVB HQoS child policies are user modifiable and NVGENed to preserve the configuration if user saves the configuration to the startup-config. So, AVB HQoS child policy configurations are retained even after reload. Information about Multiple VLAN Registration Protocol Multiple VLAN Registration Protocol (MVRP) is an application based on MRP. MVRP provides a mechanism for dynamic maintenance of the contents of Dynamic VLAN Registration Entries for each VLAN id, and for propagating the information that they contain to other Bridges.
This information allows MVRP-aware devices to dynamically establish and update their knowledge of the set of VLAN IDs associated with VLANs that currently have active members, and through which Ports those members can be reached. MVRP, from an AVB perspective, is mandatory on the talkers and the listeners. Independent of AVB, MVRP is an IEEE 802.1Q requirement on the VLAN-aware switches. However, manual configuration of VLANS on the switches is sufficient for AVB. VTP should be in the disabled mode or transparent mode for MVRP to work.
