Configuring Arp Mad - HP 5120-24G EI Configuration Manual

Use dynamic link aggregation mode. MAD is LACP dependent. Even though LACP MAD can be
•
configured on both static and dynamic aggregate interfaces, it takes effect only on dynamic
aggregate interfaces.
Configure link aggregation settings also on the intermediate device.
•
To configure LACP MAD:
Step
1. Enter system view.
2. Assign a domain ID to the IRF
fabric.
3. Create an aggregate
interface and enter
aggregate interface view.
4. Configure the aggregation
group to operate in dynamic
aggregation mode.
5. Enable LACP MAD.
6. Return to system view.
7. Enter Ethernet interface view.
8. Assign the Ethernet interface
to the specified aggregation
group.

Configuring ARP MAD

When you configure ARP MAD, follow these guidelines:
Use a VLAN dedicated to ARP MAD.
•
If an intermediate device is used, you can use common data links as ARP MAD links. If no
•
intermediate device is used, set up dedicated ARP MAD links between IRF member devices.
• If an intermediate device is used, make sure the following requirements are met:
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 splits.

The default IRF domain ID is 0.
Use either command.
Perform this step also on the
intermediate device.
By default, an aggregation
group operates in static
aggregation mode.
Perform this step also on the
intermediate device.
By default, LACP MAD is
disabled.
