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 more information on this topic.
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.
