Usage guidelines 
If the active IRF fabric has failed to work before the IRF split problem is fixed, use this command to 
restore an IRF fabric in Recovery state. The recovered IRF fabric will take over the active IRF fabric 
role.  
Examples 
# Restore the normal MAD state of the IRF fabric in Recovery state. 
<Sysname> system-view 
[Sysname] mad restore 
   This command will restore the device from multi-active conflict state. Continue? [Y/N]:Y 
Restoring from multi-active conflict state, please wait... 
port group interface 
Use port group interface to bind a network interface to an IRF port. 
Use undo port group interface to remove the binding of a network interface and an IRF port. 
Syntax 
port group interface interface-type interface-number [ type { control | data } ] 
undo port group interface interface-name 
Default 
No network interfaces are bound to an IRF port.

Parameters 
interface-type interface-number: Specifies a network interface by its type and number. 
interface-name: Specifies a network interface in the interface-typeinterface-number format. No 
space is allowed between the interface-type and interface-number arguments. 
type: Specifies a channel type for the IRF link. The hybrid channel type applies if you do not specify 
a channel type. The link can forward both data and control packets. 
• control: Sets the link type to control. The link can forward only control packets, such as IRF 
protocol packets. 
• data: Sets the link type to data. The link can forward only data packets. 
Usage guidelines 
An IRF port must have a minimum of one hybrid channel, or a minimum of one data channel and one 
control channel. 
As a best practice to prevent control traffic from being delayed when a large amount of data traffic is 
present, use separate physical links as data and control channels. 
To change the channel type of an IRF link, you must first remove the binding, and then rebind the 
link.
