{
Enable the IRF fabric to change its bridge MAC address as soon as the address owner 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 Command Remarks
1. Enter system view. system-view N/A
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 address owner
leaves.
undo irf mac-address persistent
By default, the IRF bridge MAC
address remains unchanged for
6 minutes after the address
owner leaves.
4. Create a VLAN dedicated to
ARP MAD.
vlan vlan-id
The default VLAN on the device
is VLAN 1.
5. Return to system view. quit N/A
6. Enter Ethernet interface view
or interface range view.
• Enter interface range view:
{
Method 1:
interface range { interface-type
interface-number [ to
interface-type
interface-number ] } &<1-5>
{
Method 2:
interface range name name
[ interface { interface-type
interface-number [ to
interface-type
interface-number ] } &<1-5> ]
• Enter interface view:
interface interface-type
interface-number
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.
7. 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 }
The link type of ARP MAD ports
can be access, trunk, or hybrid.
The default link type of a port is
access.
8. Return to system view. quit N/A
9. Enter VLAN interface view.
interface vlan-interface
vlan-interface-id
N/A
10. Assign the interface an IP
address.
ip address ip-address { mask |
mask-length } By default, no IP address is
assigned to any VLAN interface.
