R211x-HP Flexfabric 11900 IRF Configuration Guide

14
• If two IRF fabrics have the same bridge MAC address, they cannot merge.
• Assign each member a unique IRF member ID to make sure they can merge. You must reboot the
members to validate the IRF member ID settings.
• Assign the highest member priority to the device you want to use as the master.
• Save any configuration you have made to the startup configuration file before you reboot the IRF
member devices.
Setup and configuration task list
HP recommends the following IRF fabric setup and configuration procedure:

rocedure Remarks
1. (Required.) Planning the IRF fabric setup
N/A
2. (Required.) Preconfiguring IRF member devices in standalone mode:
{ Assigning a member ID to each IRF member device
{ Specifying a priority for each member device
{ Binding physical ports to IRF ports
Perform this task on each member
device before the IRF mode is
enabled.
3. (Required.) Saving configuration to the next-startup configuration file
N/A
4. (Required.) Connecting physical IRF ports
Make sure that they are
interoperable.
5. (Required.) Setting the operating mode to IRF mode
N/A
6. (Required.) Accessing the IRF fabric
N/A
7. (Optional.) Configuring IRF member devices in IRF mode:
{ Assigning an IRF domain ID to the IRF fabric
{ Changing the member ID of a device
{ Changing the priority of a member device
{ Adding physical ports to an IRF port
{ Enabling IRF auto merge
{ Configuring a member device description
{ Configuring IRF link load sharing mode
{ Configuring IRF bridge MAC persistence
{ Enabling software auto-update for system software image
synchronization
{ Setting the IRF link down report delay
{ Configuring MAD
Adding physical ports to an IRF port
is required if you did not configure
IRF port bindings in standalone
mode.
CAUTION:
Changing member IDs in an IRF
fabric can void member ID-related
configuration and cause
unexpected problems. Before doing
that, make sure you understand the
impact on your live network.
Planning the IRF fabric setup
Consider the following items when you plan an IRF fabric:
• Hardware compatibility and restrictions
• IRF fabric size
• Master device
• IRF physical ports
