Binding physical interfaces to IRF ports

When you bind physical interfaces to IRF ports, follow these guidelines:

On a physical interface bound to an IRF port, you can execute only the description, flow-interval, and shutdown commands. For more information about these commands, see Layer 2—LAN Switching Command Reference.

To bind physical interfaces to IRF ports:

Step

Command

Remarks

1. Enter system view.

system-view

N/A

2. Enter interface view or interface range view.

  • Enter interface range view:interface range { interface-type interface-number [ to interface-type interface-number ] } &<1-24>

  • Enter interface view:interface interface-type interface-number

To shut down a range of IRF physical interfaces, enter interface range view.

To shut down one IRF physical interface, enter its interface view.

3. Shut down the interface or the range of interfaces.

shutdown

By default, all interfaces are up.

4. Return to system view.

quit

5. Enter IRF port view.

irf-port member-id/port-number

N/A

6. Bind each physical interface to the IRF port.

port group interface interface-type interface-number

By default, no physical interfaces are bound to any IRF port.

Repeat this step to assign multiple physical interfaces to the IRF port for link redundancy.

You can bind a maximum of four physical interfaces to an IRF port.

7. Return to system view.

quit

N/A

8. Enter interface view or interface range view.

  • Enter interface range view:interface range { interface-type interface-number [ to interface-type interface-number ] } &<1-24>

  • Enter interface view:interface interface-type interface-number

N/A

9. Bring up the interface or the range of interfaces.

10. Return to system view.

11. Save the configuration.

Activating IRF port settings causes IRF merge and reboot. To avoid data loss, save the running configuration to the startup configuration file before you perform the operation.

12. Activate the IRF port settings.

After this step is performed, the state of the IRF port changes to UP, the member devices elect a master automatically, and the subordinate device reboots automatically.

After the IRF fabric is formed, you can add additional physical interfaces to an IRF port (in UP state) without repeating this step.
