HP 12500 SERIES Configuration Manual page 37

Use a VLAN dedicated to ARP MAD.
•
If an intermediate device is used, do the following:
•
Run the spanning tree feature between the IRF fabric and the intermediate device.
Enable the IRF fabric to change its bridge MAC address as soon as the master leaves.
Create an ARP MAD VLAN and assign the ports on the ARP MAD links to the VLAN.
If the intermediate device is in an IRF fabric, assign this fabric a different domain ID than
the ARP MAD-enabled fabric to avoid false detection of IRF split.
To configure ARP MAD:
Step
1. Enter system view.
2. Assign a domain ID to the
IRF fabric.
3. Configure the IRF bridge
MAC address to change as
soon as the master leaves.
4. Create a VLAN dedicated to
ARP MAD.
5. Return to system view.
6. Enter Ethernet interface
view or interface range
view.

Remarks
N/A
The default IRF domain ID is 0.
You can change the IRF domain
ID only in the Admin MDC. The
domain ID setting takes effect
on all MDCs.
By default, the IRF fabric's
bridge MAC address persists
permanently even after the
master leaves.
The default VLAN on the device
is VLAN 1.
N/A
To assign a range of ports to
the ARP MAD VLAN, enter
interface range view.
To assign one port to the ARP
MAD VLAN, enter Ethernet
interface view.
