Assign the port to the ND MAD VLAN. • Assign the port to the VLAN as an access port: port access vlan vlan-id Choose one command depending on the port type. • Assign the port to the VLAN as a trunk port: ND MAD detection has no port trunk permit vlan vlan-id requirement for the link type of the detection port. • Assign the port to the VLAN as a hybrid port: The default link type of a port is port hybrid vlan vlan-id { tagged | access. untagged } 8.

Enable ND MAD. ipv6 address { ipv6-address/pre-length | ipv6 address pre-length } mad nd enable By default, no IPv6 address is assigned to any VLAN interface. By default, ND 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 network 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 I and inactive IRF fabrics. 30

Command
Remarks
1.
Enter system view.

2.
Assign a domain ID to the IRF
fabric.
irf domain
domain-id
The default IRF domain ID is 0.
3.
Configure the IRF bridge
MAC address to change as
soon as the master leaves.
undo irf mac-address persistent
By default, the IRF fabric
preserves its bridge MAC
address for 6 minutes after the
master leaves.
4.
Create a VLAN dedicated to
ND MAD.
vlan

The default VLAN on the device
is VLAN 1.
5.
Return to system view.

6.
Enter Ethernet interface view.

7.
Assign the port to the ND
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
{

Choose one command
depending on the port type.
ND MAD detection has no
requirement for the link type of
the detection port.
The default link type of a port is
access.

10.
Assign the interface an IP
address.

By default, no IPv6 address is
assigned to any VLAN interface.
11.
Enable ND MAD.

By default, ND 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 network 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 I and inactive IRF fabrics.
