Parameters

Description

Use the chassis convert mode irf command to switch the operating mode of the switch to Intelligent

Resilient Framework (IRF) mode.

Use the undo chassis convert mode command to switch the operating mode of the switch to standalone

mode.

The switch operates in standalone mode when shipped. If the operating mode is switched, the switch

reboots automatically to make the new operating mode take effect. If the operating mode is not

switched, the switch operates in the same mode when it reboots.

Configure the operating mode of the switch according to the network requirements: when the operating

mode switches to IRF, an IRF fabric is formed even if there is only one member. A one-member IRF fabric

also needs to be managed and maintained, and thus consumes system resources. Therefore, if a switch

does not need to form an IRF fabric with other switches, you are recommended to configure its

operating mode as standalone mode.

Configure the operating mode of the switch according to the network requirements: when the operating

mode of the switch switches to IRF, an IRF fabric is formed even if there is only one member. A

one-member IRF fabric also needs to be managed and maintained, and thus consumes system

resources. Therefore, if a switch does not need to form an IRF fabric with other devices, H3C

recommends that you configure its operating mode as standalone mode.

• As soon as you switch the operating mode, the switch automatically reboots to make the changes

effective. It is a good practice to save the running configuration before switching operating mode.

• If the member ID of the device is not set, you must first set the member ID of the switch, and then

execute the chassis convert mode irf command. To display the member ID of the switch, use the

display irf configuration command. If the MemberID field is displayed as —, the member ID of the

switch is not set yet.

• To avoid member ID collision with other members when the switch is added into an IRF fabric, plan

the member ID of this switch when it operates in standalone mode.

• For a switch operating in IRF mode, you cannot configure the system working mode to hybrid. For

more information about the system working mode, see Fundamentals Configuration Guide.
