Step
7. Assign the port or the
range of ports to the ARP
MAD VLAN.
8. Return to system view.
9. Enter VLAN interface view.
10. Assign the interface an IP
address.
11. Enable ARP MAD.
Excluding a port from the shutdown action upon detection of multi-active collision
When the IRF fabric transits to the Recovery state, all ports but the console and physical IRF ports
by default automatically shut down.
You can exclude a port from the shutdown action for management or other special purposes. For
example:
Exclude a port from the shutdown action, so you can Telnet to the port for managing the
•
device.
Exclude a VLAN interface and its Layer 2 ports from the shutdown action, so you can log in
•
through the VLAN interface.
CAUTION:
Excluding a VLAN interface and its Layer 2 ports from the shutdown action introduces IP collision
risks because the VLAN interface might be active on both the IRF fabric in Active state and the IRF
fabric in Recovery state.
To configure a port to not shut down when the IRF fabric transits to the Recovery state:
Step
1. Enter system view.
Command
•
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 }
quit
interface vlan-interface
vlan-interface-id
ip address ip-address { mask |
mask-length }
mad arp enable

depending on the port type.
ARP MAD has no requirement
for the link type.
The default link type of a port
is access.

By default, no IP address is
assigned to any VLAN
interface.
By default, ARP MAD is
disabled.
After ARP MAD is enabled, the
system instructs you to assign
an IRF domain ID. At the
prompt, enter a new domain ID
or press Enter to confirm the
domain ID you have assigned.
The IRF domain ID takes effect
on all MDCs in the IRF fabric.
