Specifying A Priority For A Stack Member; Specifying The Preservation Time Of Stack Bridge Mac Address - H3C LS-3100-52P-OVS-H3 Operation Manual

The above setting takes effect after the reboot of the device.
You can use the display irf configuration command to view the current member ID of the device
and the member ID will be used after the device reboot.
In an IRF stack, member IDs are not only used to identify devices, but also used to identify the port
configurations on different member devices in the configuration file. Therefore, modifying a
member ID may cause device configuration changes or even losses, so modify member ID with
caution. For example, three members (of same device model) with the member IDs of 1, 2 and 3
are connected to a stack port. Suppose that each member has several ports: change the member
ID of device 2 to 3, change that of device 3 to 2, reboot both devices, and add them into the stack
again. Then device 2 will use the original port configurations of device 3, and device 3 will use
those of device 2.

Specifying a Priority for a Stack Member

Each stack member has a priority. During the master election, a member with the greatest priority will be
elected as the master.
The priority of a device defaults to 1. You can modify the priority through command lines. The greater
the priority value, the higher the priority. A member with a higher priority is more likely to be a master,
and more likely to preserve its ID in a member ID collision.
Follow these steps to specify a priority for a stack member:

The setting of priority takes effect right after your configuration without the need of rebooting the device.

Specifying the Preservation Time of Stack Bridge MAC Address

A device uses the bridge MAC address when it communicates with the outside as a network bridge. A
bridge device on the network has its unique bridge MAC address. Some Layer 2 protocols (like LACP)
use bridge MAC addresses to identify different devices. During the forwarding of Layer 2 packets, if the
destination MAC address of a packet is the bridge MAC address of a device, it means that the packet is
sent to this device.
In an IRF stack, the bridge MAC address of a member device is called member bridge MAC address.
The stack communicates with the outside as a single device; therefore, it also has a bridge MAC
