Running QoS within a VCS stack

In general you can apply the same principles when configuring QoS on a
VCS stack as you would for single switch; however there are a few specific
changes that you will need to make. See the AlliedWare Plus Software
Reference

Stack Member

Failure and

Recovery

Management IP Addresses

A single virtual MAC address, from the current Master, is used as the stack
MAC address. If the stack master fails, the stack MAC address changes to
reflect the new master's MAC address. If the stack MAC address does
change, ARP tables of devices on the network are updated to reflect the
change in MAC address via gratuitous ARP.
