•
You must use all or none of the four 10-GE breakout interfaces for IRF links. The four breakout
interfaces can be bound to different IRF ports.
•
Before you bind one 10-GE breakout interface to an IRF port or remove it from the IRF port, you must
shut down all the 10-GE breakout interfaces. If any of the breakout interfaces are in up state, the
bind or remove action will fail.
•
Bring up the breakout interfaces after you complete the operations.
Connecting IRF ports
When you connect two neighboring IRF members, follow these restrictions and guidelines:
•
You must connect the physical interfaces of IRF-port 1 on one member to the physical interfaces of
IRF-port 2 on the other.
•
Do not connect physical interfaces of both IRF ports on one member device to the physical
interfaces of both IRF ports on the other.
Feature compatibility and configuration restrictions
To form an IRF fabric, all member devices in the IRF fabric must use the same ACL hardware mode. For
more information about hardware-based ACLs, see ACL and QoS Configuration Guide.
Configuration backup
H3C recommends that you back up the next-startup configuration file on a device before adding the
device to an IRF fabric as a subordinate.
A subordinate device's next-startup configuration file might be overwritten if the master and the
subordinate use the same file name for their next-startup configuration files. You can use the backup file
to restore the original configuration after removing the subordinate from the IRF fabric.
