Step Command Remarks
4. 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 Ethernet interface view:
interface interface-type
interface-number
To assign a range of ports to the
BFD MAD VLAN, enter interface
range view.
To assign one port to the BFD
MAD VLAN, enter Ethernet
interface view.
5. Assign the port or the port
range to the BFD 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.
BFD MAD has no requirement
for the link type of the detection
port.
The default link type of a port is
access.
6. Return to system view. quit N/A
7. Enter VLAN interface view.
interface vlan-interface
interface-number
N/A
8. Enable BFD MAD. mad bfd enable
By default, BFD MAD is
disabled.
9. Configure a MAD IP address
for the VLAN interface on the
specified member.
mad ip address ip-address { mask |
mask-length } member member-id
By default, no MAD IP address is
configured on any VLAN
interface.
Repeat this step to assign a MAD
IP address to each member
device on the VLAN interface.
The MAD IP address must not be
on the same subnet as any IP
address configured on any
member device.
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:
