IRF split

IRF split occurs when an IRF fabric breaks up into two or more IRF fabrics because of IRF link failures, as
shown in Figure
forwarding problems on the network. To quickly detect a multi-active collision, configure a minimum of
one MAD mechanism (see
Figure 3 IRF split

IRF merge

IRF merge occurs when two split IRF fabrics reunite or when two independent IRF fabrics are united, as
shown in Figure

Member priority

Member priority determines the possibility of a member device to be elected the master. A member with
higher priority is more likely to be elected the master.
The default member priority is 1. You can change the member priority of a device to affect the master
election result.

Interface naming conventions

An interface is named in the chassis-number/slot-number/port-index format.
chassis-number—IRF member ID of the switch. This argument defaults to 1. The IRF member ID
•
always takes effect regardless of whether the switch is part of an IRF fabric.
• slot-number—Slot number of the front panel. This argument is fixed at 0.
port-index—Index of the port on the device. Port index depends on the number of ports available
•
on the device. To identify the index of a port, look at its port index mark on the chassis.
Look at the following examples:
