Operating Mode; Irf Member Roles - HP 10500 Series Configuration Manual

Figure 2 Two-chassis IRF fabric implementation schematic diagram
In this figure, Device A and Device B form a two-chassis IRF fabric that has four MPUs (one active and
three standbys) and two times the number of interface cards that a single device provides. The IRF fabric
manages the physical and software resources of Device A and Device B in a centralized manner.

Operating mode

The device operates in one of the following modes:
Standalone mode—The device cannot form an IRF fabric with other devices.
•
IRF mode—The device can form an IRF fabric with other devices.
•

IRF member roles

IRF uses two member roles: master and standby (called "subordinate" throughout the documentation).
When devices form an IRF fabric, they elect a master to manage the IRF fabric, and all other devices back
up the master. When the master device fails, the other devices elect a new master automatically. For more
information about master election, see "Master election."
