General restrictions and configuration guidelines
To ensure a successful IRF setup, read the configuration restrictions and guidelines carefully before you
connect and set up an IRF fabric.
All IRF member devices must run the same system software image version.
A 12500 IRF fabric can have up to four chassis.
MPU and IRF physical port restrictions
When you set up an IRF fabric, follow these MPU restrictions and guidelines:
Every IRF member must have at least one MPU.
All member devices must use the same type of MPUs.
To use enhanced IRF, make sure each IRF member has two MPUs.
Selecting IRF physical ports
You must use Layer 2 Ethernet fiber or copper ports for IRF connection. HP recommends using 10-GE fiber
ports for high performance.
IRF physical port binding restrictions
When you bind IRF physical ports to IRF ports, follow these restrictions and guidelines:
Link aggregation member ports cannot be bound to an IRF port. To bind them to an IRF port, you
must first remove them from the aggregation group.
If multiple physical links are used between two member chassis, bind them all to IRF-port 1 on one
chassis and to IRF-port 2 on the other. If the number of physical ports at the two ends of an
aggregate IRF link differs, the IRF fabric cannot be formed.
In IRF mode, use the shutdown command to shut down a physical port before you bind it to or
remove it from an IRF port. In standalone mode, the shutdown operation is not required.
Make sure you have brought up the IRF physical ports after you complete the binding operation.
Connecting IRF ports
When you connect two neighboring IRF members, connect the physical ports of IRF-port 1 on one
member to the physical ports of IRF-port 2 on the other.
