Mad; Other Configuration Guidelines; Setup And Configuration Task List - HP 12500 SERIES Configuration Manual

All member devices in the IRF fabric must use the same ACL hardware mode. For more
•
information about hardware-based ACLs, see ACL and QoS Configuration Guide.
All member devices in the IRF fabric must have the same vpn popgo command setting. For
•
more information about vpn popgo, see MPLS Configuration Guide.
All member devices in the IRF fabric must have the same irf mode enhanced command
•
configuration.
All member devices in the IRF fabric must work in the same system operating mode. For more
•
information about the system operating mode, see Fundamentals Configuration Guide.

MAD

LACP MAD handles collisions in a different way than BFD MAD and ARP MAD. To avoid
•
conflicts, do not enable LACP MAD together with BFD MAD or ARP MAD in an IRF fabric.
However, you can configure BFD MAD and ARP MAD together in an IRF fabric for prompt IRF
split detection.
If LACP MAD or ARP MAD runs between two IRF fabrics, assign each fabric a unique IRF
•
domain ID. For BFD MAD, this task is optional.
To exclude a port from the shutdown action that is executed when an IRF fabric transits to the
•
Recovery state, use the mad exclude interface command. To bring up a port after the IRF
fabric transits to the Recovery state, you must use the mad restore command to activate the
entire IRF fabric, rather than using the undo shutdown command.

Other configuration guidelines

If a standby device uses the same next-startup configuration file name as the master device,
•
the file might be overwritten depending on your configuration file management settings. To
continue to use the configuration file after removing the device from the IRF fabric, back up
the file before setting up the IRF fabric.
Strictly follow the IRF fabric setup procedure described in
•
plan the IRF fabric, identify IRF physical ports, connect IRF member devices, and configure
basic settings.
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.
If two IRF fabrics have the same bridge MAC address, they cannot merge.
•
Assign the highest member priority to the device you want to use as the master.
•
Assign the IRF fabric a unique IRF domain ID in a multi-IRF network.
•
Save any configuration you have made to the startup configuration file before rebooting the
•
IRF member devices.
