Setting the operating mode to IRF mode
By default, the device is operating in standalone mode. To assign the device to an IRF fabric, you must
change its operating mode to IRF mode.
Before changing to IRF mode, use the display irf configuration command to verify that a member ID has
been assigned to the device. If the MemberID field displays two hyphens (--), first assign a member ID to
the device.
To set the operating mode of a device to IRF mode:

The default operating mode is
standalone mode.
After you change the operating mode, the device automatically reboots to validate the change.
During the reboot, you may choose to have the system automatically convert the startup configuration file
to prevent some slot- or interface-related configurations from becoming invalid. For example, the system
can convert the slot slot-number parameter set in standalone mode to the chassis chassis-number slot
slot-number parameter in IRF mode, and add the chassis ID in an interface number.
To restore the standalone mode, use the undo chassis convert mode command.
TIP:
IRF generates packets on a device in IRF mode even if the device does not form an IRF fabric with any other
device. To protect system resources, set a device to operate in standalone mode after removin
g
it from an
IRF fabric.
Accessing the IRF fabric
The IRF fabric appears as one device after it is formed. You configure and manage all IRF members at the
CLI of the global active MPU. All settings you made are automatically propagated to the IRF members.
When you log in to an IRF fabric, you are placed at the CLI of the global active MPU, regardless of at
which member device you are logged in. After that, you can access the CLI of a standby MPU to execute
a limited set of maintenance commands.
The IRF fabric supports up to five concurrent VTY users. The maximum number of concurrent console users
equals the total number of MPUs in the IRF fabric.
Accessing the global active MPU of the IRF fabric
Access an IRF fabric in one of the following ways:
• Local login—Log in through the console port of a member device.
• Remote login—Remotely log in at a Layer 3 Ethernet interface on any member device by using
methods including Telnet, Web, and SNMP.
