R21xx-HP FlexFabric 11900 IRF Configuration Guide

# Connect the two devices as shown in Figure 13.

# Enable IRF mode.

<Sysname> system-view

[Sysname] chassis convert mode irf

The device will switch to IRF mode and reboot. You are recommended to save the current

running configuration and specify the configuration file for the next startup.

Continue? [Y/N]:y

Do you want to convert the content of the next startup configuration file

flash:/startup.cfg to make it available in IRF mode? [Y/N]:y

Please wait...

Saving the converted configuration file to the main board succeeded.

Slot 1:

Saving the converted configuration file succeeded.

Now rebooting, please wait...

Device B and Device A form an IRF fabric after Device B reboots.

3. Configure LACP MAD:

# Assign domain ID 1 to the IRF fabric.

<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

MAD LACP only enable on dynamic aggregation interface.

[Sysname-Bridge-Aggregation2] quit

# Assign GigabitEthernet 1/4/0/2 and GigabitEthernet 2/4/0/2 to the aggregate interface.

[Sysname] interface gigabitethernet 1/4/0/2

[Sysname-GigabitEthernet1/4/0/2] port link-aggregation group 2

[Sysname-GigabitEthernet1/4/0/2] quit

[Sysname] interface gigabitethernet 2/4/0/2

[Sysname-GigabitEthernet2/4/0/2] port link-aggregation group 2

4. Configure Device C as the intermediate device:

CAUTION:

If the intermediate device is in an IRF fabric, you must assign this fabric a different domain ID than the

LACP MAD-enabled IRF fabric.

# 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 GigabitEthernet 4/0/1 and GigabitEthernet 4/0/2 to the aggregate interface.
