Command Remarks
6. Assign the port or the range
of ports to the ARP MAD
VLAN.
• 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 }
Choose one command
depending on the port type.
ARP MAD has no requirement
for the link type.
The default link type of a port is
access.
7. Return to system view.
quit N/A
8. Enter VLAN interface view.
interface vlan-interface
vlan-interface-id
N/A
9. Assign the interface an IP
address.
ip address ip-address { mask |
mask-length }
By default, no IP address is
assigned to any VLAN interface.
10. Enable ARP MAD.
mad arp enable
By default, ARP MAD is
disabled.
Excluding a port from the shutdown action upon detection of multi-active collision
By default, all ports except the console and physical IRF ports shut down automatically when the IRF
fabric transits to the Recovery state.
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 active IRF fabric and the inactive IRF fabric.
To configure a port to not shut down when the IRF fabric transits to the recovery state:

2. Configure a port to not shut
down when the IRF fabric
transits to the Recovery state.
mad exclude interface interface-type
interface-number
By default, when an IRF fabric
transits to the Recovery state, all
its network ports except the IRF
physical ports and console port
are shut down.
Recovering an IRF fabric
After the failed IRF link between two split IRF fabrics is recovered, log in to the inactive IRF fabric and use
the reboot command to reboot all its members. After these member devices join the active IRF fabric as
subordinates, IRF merge is complete, as shown in Figure 12.
