Enabling IRF auto-merge
About this task
When two IRF fabrics merge, you must reboot the member devices in the IRF fabric that fails in the
master election. The auto-merge feature enables the IRF fabric to automatically reboot all its
member devices to complete the merge.
If this feature is disabled, you must manually reboot the devices that failed the master election to
complete the merge.
Procedure
1.
Enter system view.
system-view
2.
Enable IRF auto-merge.
irf auto-merge enable
By default, this feature is enabled.
Configuring a member device description
1.
Enter system view.
system-view
2.
Configure a description for a member device.
irf member member-id description text
By default, no member device description is configured.
Configuring the IRF bridge MAC address
About this task
The bridge MAC address of a system must be unique on a switched LAN. IRF bridge MAC address
identifies an IRF fabric by Layer 2 protocols (for example, LACP) on a switched LAN.
By default, an IRF fabric uses the bridge MAC address of the master as the IRF bridge MAC address.
After the master leaves, the IRF bridge MAC address persists for a period of time or permanently
depending on the IRF bridge MAC persistence setting. When the IRF bridge MAC persistence timer
expires, the IRF fabric uses the bridge MAC address of the current master as the IRF bridge MAC
address.
The following is how IRF handles the IRF bridge MAC address if IRF fabrics merge:
•
When IRF fabrics merge, IRF ignores the IRF bridge MAC address and checks the bridge MAC
address of each member device in the IRF fabrics. IRF merge fails if any two member devices
have the same bridge MAC address.
•
After IRF fabrics merge, the merged IRF fabric uses the bridge MAC address of the merging
IRF fabric that won the master election as the IRF bridge MAC address.
Restrictions and guidelines
CAUTION:
The bridge MAC address change causes transient traffic disruption.
When you configure IRF bridge MAC persistence, follow these restrictions and guidelines:
•
If the IRF fabric has multichassis aggregate links, do not use the
undo irf mac-address
persistent
command. Use of this command might cause traffic disruption.
