Parameters

mac-address: Specifies a MAC address in the format of H-H-H. The MAC address cannot be the

all-zero or all-F MAC address, or a multicast MAC address. You can omit the consecutive zeros at

the beginning of each segment. For example, you can enter f-e2-1 for 000f-00e2-0001.

Usage guidelines

CAUTION:

IRF bridge MAC address change causes transient traffic disruption.

This command is available in IRF mode and in Release 2138 and later versions.

When you change the operating mode from IRF to standalone, the IRF bridge MAC address

configuration is lost, regardless of whether you have saved the configuration.

On a switched LAN, the IRF bridge MAC address must be unique.

When IRF fabrics merge, IRF ignores the configured IRF bridge MAC address and only checks the

bridge MAC address of each member device in the IRF fabrics. IRF merge fails if any of the

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 whose master has the higher priority as the IRF bridge MAC address.

If an IRF fabric splits after you configure the IRF bridge MAC address, both the split IRF fabrics use

the configured bridge MAC address as the IRF bridge MAC address.

Examples

# Configure the IRF fabric to use c4ca-d9e0-8c3c as the IRF bridge MAC address.
