Enabling Irf Auto Merge; Configuring A Member Device Description; Configuring Irf Bridge Mac Persistence - HPE FlexNetwork HSR6800 Configuration Manual

Enabling IRF auto merge

When two IRF fabrics merge, you must reboot the member devices in the IRF fabric that fails in the
master election. The auto merge function enables the IRF fabric to automatically reboot all its
member devices to complete the merge.
This function can work only when it is enabled on both IRF fabrics that are merging.
The IRF auto merge function does not take effect on the IRF fabric merge caused by binding a
physical port to an IRF port in IRF mode. You must manually reboot the devices that have been
defeated in the master selection to complete the merge.
To enable IRF auto merge:
Step
1. Enter system view.
2. Enable IRF auto merge.

Configuring a member device description

You can configure a description to describe the location or purpose of a member device.
To configure a description for a member device:
Step
1. Enter system view.
2. Configure the description of
a member.

Configuring IRF bridge MAC persistence

An IRF fabric by default uses the bridge MAC address of the master device as its bridge MAC
address. Layer 2 protocols, such as LACP, use the bridge MAC address to identify the IRF fabric. On
a switched LAN, the bridge MAC address must be unique.
To avoid duplicate bridge MAC addresses, an IRF fabric can change its bridge MAC address
automatically after its master leaves, but the change can cause transient traffic disruption.
Depending on your network condition, enable the IRF fabric to preserve or change its bridge MAC
address after the master leaves. Available options include:
•
irf mac-address persistent timer—Bridge MAC address of the IRF fabric is retained for 6
minutes after the master leaves. If the master does not return before the timer expires, the IRF
fabric uses the bridge MAC address of the new master as its bridge MAC address. This option
avoids unnecessary bridge MAC address change due to a device reboot, transient link failure,
or purposeful link disconnection.
•
irf mac-address persistent always—Bridge MAC address of the IRF fabric does not change
after the master leaves.
•
undo irf mac-address persistent—Bridge MAC address of the new master replaces the
original one as soon as the old master leaves.
