HP FlexFabric 12500 Series Configuration Manual page 39

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 also an IRF fabric, assign the two IRF fabrics different domain IDs
for correct split detection.
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.
7. Assign the port or the range
of ports to the ARP MAD
VLAN.
Return to system view.
8.
9. Enter VLAN interface view.

•
Assign the port to the VLAN as an
access port:
port access vlan vlan-id
•
Assign the port to the VLAN as a
trunk port:
port trunk permit vlan vlan-id
•
Assign the port to the VLAN as a
hybrid port:
port hybrid vlan vlan-id { tagged |
untagged }

Remarks
N/A
The default IRF domain ID is 0.
This command can be executed
only on the default MDC.
By default, the IRF fabric's
bridge MAC address persists
permanently 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.
The link type of ARP MAD ports
can be access, trunk, or hybrid.
The default link type of a port is
access.
