Mdc; Evi Restrictions; Other Configuration Guidelines - HP FlexFabric 12500 Series Configuration Manual

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 instead of the undo shutdown
command.

MDC

If the IRF fabric splits, do not change the MDC settings on any IRF member devices before they reunite.
Except for the commands in

For more information about MDC, see "Configuring MDC."

EVI restrictions

In IRF mode, any type of outbound policies (for example, the outbound QoS policy) on an interface does
not take effect on packets that are received from an EVI tunnel.

Other configuration guidelines

If a subordinate 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
•
the IRF fabric, identify IRF physical ports, connect IRF member devices, and configure basic settings.
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.
Table 1, all IRF commands are available only on the default MDC.
