HP A7503 Configuration Manual page 39

To address the requirements for high availability, ease of management and maintenance, use IRF2
•
technology to create an IRF fabric with Device A and Device B at the access layer.
• To offset the risk of IRF fabric partition, configure MAD to detect multi-active collisions. In this
example, LACP MAD is adopted because the number of access devices tends to be large. In
addition, for the purpose of LACP MAD, an intermediate switch that support extended LACPDUs
must be used.
To reduce system reboots involved to create the IRF fabric, pre-configure the IRF ports, member ID,
•
member priority on each device in standalone mode and change their operating mode to IRF after
saving the configuration. The devices can thus form an IRF fabric.
Configuration procedure
Configure Device A
1.
# Set the member ID of Device A to 1, create IRF port 2, and bind it to physical port Ten-GigabitEthernet
3/0/1.
<Sysname> system-view
[Sysname] irf member 1
Info: Member ID change will take effect after the switch reboots and operates in IRF mode.

# Save the current configuration to the startup configuration file.
[Sysname] quit
<Sysname> save

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
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...
The device operates in IRF mode after reboot.
Configure Device B
2.
# Set the member ID of Device B to 2, create IRF port 1, and bind it to physical port Ten-GigabitEthernet
3/0/1.
