LACP MAD-enabled IRF configuration example

As shown in Figure 14, set up a four-chassis IRF fabric at the access layer of the enterprise network.

Configure LACP MAD on the multichassis aggregation to Device E, an HPE device that supports extended LACP.

1. Configure Device A:

   # Shut down the physical interfaces used for IRF links. This example uses FortyGigE 1/0/1 to FortyGigE 1/0/4 for IRF links.

   <Sysname> system-view
   [Sysname] interface range FortyGigE 1/0/1 to FortyGigE 1/0/4
   [Sysname-if-range] shutdown
   [Sysname-if-range] quit 
   

   # Bind FortyGigE 1/0/1 and FortyGigE 1/0/2 to IRF-port 1/1.

   [Sysname] irf-port 1/1
   [Sysname-irf-port1/1] port group interface FortyGigE 1/0/1
   [Sysname-irf-port1/1] port group interface FortyGigE 1/0/2
   [Sysname-irf-port1/1] quit
   

   # Bind FortyGigE 1/0/3 and FortyGigE 1/0/4 to IRF-port 1/2.

   [Sysname] irf-port 1/2
   [Sysname-irf-port1/2] port group interface FortyGigE 1/0/3
   [Sysname-irf-port1/2] port group interface FortyGigE 1/0/4
   [Sysname-irf-port1/2] quit
   

   # Bring up the SFP+ ports and save the configuration.

   [Sysname] interface range FortyGigE 1/0/1 to FortyGigE 1/0/4
   [Sysname-if-range] undo shutdown
   [Sysname-if-range] quit
   [Sysname] save
   

   # Activate the IRF port configuration.

   [Sysname] irf-port-configuration active
   

2. Configure Device B:

   # Change the member ID of Device B to 2 and reboot the device to validate the change.

   <Sysname> system-view
   [Sysname] irf member 1 renumber 2
   Renumbering the member ID may result in configuration change or loss. Continue? [Y/N]:y
   [Sysname] quit
   <Sysname> reboot
   

   # Connect Device B to Device A as shown in Figure 14, and log in to Device B. This example uses FortyGigE 2/0/1 to FortyGigE 2/0/4 for IRF links.

   # Shut down the physical interfaces.

   <Sysname> system-view
   [Sysname] interface range FortyGigE 2/0/1 to FortyGigE 2/0/4
   [Sysname-if-range] shutdown
   [Sysname-if-range] quit 
   

   # Bind FortyGigE 2/0/1 and FortyGigE 2/0/2 to IRF-port 2/1.

   [Sysname] irf-port 2/1
   [Sysname-irf-port2/1] port group interface FortyGigE 2/0/1
   [Sysname-irf-port2/1] port group interface FortyGigE 2/0/2
   [Sysname-irf-port2/1] quit
   

   # Bind FortyGigE 2/0/3 and FortyGigE 2/0/4 to IRF-port 2/2.

   [Sysname] irf-port 2/2
   [Sysname-irf-port2/2] port group interface FortyGigE 2/0/3
   [Sysname-irf-port2/2] port group interface FortyGigE 2/0/4
   [Sysname-irf-port2/2] quit
   

   # Bring up the QSFP+ ports and save the configuration.

   [Sysname] interface range FortyGigE 2/0/1 to FortyGigE 2/0/4
   [Sysname-if-range] undo shutdown
   [Sysname-if-range] quit
   [Sysname] save
   

   # Activate the IRF port configuration.

   [Sysname] irf-port-configuration active
   

   The two devices perform master election, and the one that has lost the election reboots to form an IRF fabric with the master.

3. Configure Device C:

   # Change the member ID of Device C to 3 and reboot the device to validate the change.

   <Sysname> system-view
   [Sysname] irf member 1 renumber 3
   Renumbering the member ID may result in configuration change or loss. Continue? [Y/N]:y
   [Sysname] quit
   <Sysname> reboot
   

   # Connect Device C to Device A as shown in Figure 14, and log in to Device C. This example uses FortyGigE 3/0/1 to FortyGigE 3/0/4 for IRF links.

   # Shut down the physical interfaces.

   <Sysname> system-view
   [Sysname] interface range FortyGigE 3/0/1 to FortyGigE 3/0/4
   [Sysname-if-range] shutdown
   [Sysname-if-range] quit 
   

   # Bind FortyGigE 3/0/1 and FortyGigE 3/0/2 to IRF-port 3/1.

   [Sysname] irf-port 3/1
   [Sysname-irf-port3/1] port group interface FortyGigE 3/0/1
   [Sysname-irf-port3/1] port group interface FortyGigE 3/0/2
   [Sysname-irf-port3/1] quit
   

   # Bind FortyGigE 3/0/3 and FortyGigE 3/0/4 to IRF-port 3/2.

   [Sysname] irf-port 3/2
   [Sysname-irf-port3/2] port group interface FortyGigE 3/0/3
   [Sysname-irf-port3/2] port group interface FortyGigE 3/0/4
   [Sysname-irf-port3/2] quit
   

   # Bring up the QSFP+ ports and save the configuration.

   [Sysname] interface range FortyGigE 3/0/1 to FortyGigE 3/0/4
   [Sysname-if-range] undo shutdown
   [Sysname-if-range] quit
   [Sysname] save
   

   # Activate the IRF port configuration.

   [Sysname] irf-port-configuration active
   

   Device C reboots to join the IRF fabric.

4. Configure Device D:

   # Change the member ID of Device D to 4 and reboot the device to validate the change.

   <Sysname> system-view
   [Sysname] irf member 1 renumber 4
   Renumbering the member ID may result in configuration change or loss. Continue? [Y/N]:y
   [Sysname] quit
   <Sysname> reboot
   

   # Connect Device D to Device B and Device C as shown in Figure 14, and log in to Device D. This example uses FortyGigE 4/0/1 to FortyGigE 4/0/4 for IRF links.

   # Shut down the physical interfaces.

   <Sysname> system-view
   [Sysname] interface range FortyGigE 4/0/1 to FortyGigE 4/0/4
   [Sysname-if-range] shutdown
   [Sysname-if-range] quit 
   

   # Bind FortyGigE 4/0/1 and FortyGigE 4/0/2 to IRF-port 4/1.

   [Sysname] irf-port 4/1
   [Sysname-irf-port4/1] port group interface FortyGigE 4/0/1
   [Sysname-irf-port4/1] port group interface FortyGigE 4/0/2
   [Sysname-irf-port4/1] quit
   

   # Bind FortyGigE 4/0/3 and FortyGigE 4/0/4 to IRF-port 4/2.

   [Sysname] irf-port 4/2
   [Sysname-irf-port4/2] port group interface FortyGigE 4/0/3
   [Sysname-irf-port4/2] port group interface FortyGigE 4/0/4
   [Sysname-irf-port4/2] quit
   

   # Bring up the QSFP+ ports and save the configuration.

   [Sysname] interface range FortyGigE 4/0/1 to FortyGigE 4/0/4
   [Sysname-if-range] undo shutdown
   [Sysname-if-range] quit
   [Sysname] save
   

   # Activate the IRF port configuration.

   [Sysname] irf-port-configuration active
   

   Device D reboots to join the IRF fabric. A four-chassis IRF fabric is formed.

5. Configure LACP MAD on the IRF fabric:

   # Set the domain ID of the IRF fabric to 1.

   <Sysname> system-view
   [Sysname] irf domain 1
   

   # Create a dynamic aggregate interface and enable LACP MAD.

   [Sysname] interface bridge-aggregation 2
   [Sysname-Bridge-Aggregation2] link-aggregation mode dynamic
   [Sysname-Bridge-Aggregation2] mad enable
   You need to assign a domain ID (range: 0-4294967295)
   [Current domain is: 1]:
    The assigned  domain ID is: 1
    Info: MAD LACP only enable on dynamic aggregation interface.
   [Sysname-Bridge-Aggregation2] quit
   

   # Assign FortyGigE 1/0/5, FortyGigE 2/0/5, FortyGigE 3/0/5, and FortyGigE 4/0/5 to the aggregate interface.

   [Sysname] interface range FortyGigE 1/0/5 FortyGigE 2/0/5 FortyGigE 3/0/5 FortyGigE 4/0/5
   [Sysname-if-range] port link-aggregation group 2
   [Sysname-if-range] quit
   

6. Configure Device E as the intermediate device:

   	CAUTION: If the intermediate device is also an IRF fabric, assign the two IRF fabrics different domain IDs for correct split detection. False detection causes IRF split.

   # Create a dynamic aggregate interface.

   <Sysname> system-view
   [Sysname] interface bridge-aggregation 2
   [Sysname-Bridge-Aggregation2] link-aggregation mode dynamic
   [Sysname-Bridge-Aggregation2] quit
   

   # Assign FortyGigE 1/0/1, FortyGigE 1/0/2, FortyGigE 1/0/3, and FortyGigE 1/0/4 to the aggregate interface.

   [Sysname] interface range FortyGigE 1/0/1 to FortyGigE 1/0/4
   [Sysname-if-range] port link-aggregation group 2
   [Sysname-if-range] quit
