Chapter 10 Virtualization Configuration

10-7

The topology of Bfd mad detection is simpler then lacp. But, one vlan is selected for

bfd mad detection once, this vlan and the ports in it will be as the specific vlan and ports of

bfd mad and they cannot be configured other functions.

Construction method: select one port on member1 and select one port on member2.

Connect them with a line.

Figure 10-8 BFD MAD detection

BFD MAD detection is achieved through BFD protocol. For BFD MAD detection

function running normally, enable BFD MAD detection function under the layer3 interface

and configure MAD IP address on this interface. The difference between MAD IP address

and the ordinary IP address is that MAD IP address is bond to the member device, each

member device in VSF should configured it and they must belong to the same network

segment.

When VSF is running normally, only the MAD IP address configured on master is

effective, the MAD IP associated with the slave device is not effective, BFD session is

under the status of down.

When the VSF is split into two vsf, the mad ip address associated with the member

on the new vsf becomes effective. Through the connection line of bfd mad detection, the

bfd session will be created between the two vsf to detect the multiple Active conflict.

10.1.2

Relevant VSF Configuration

10.1.2.1 VSF Configuration

VSF configuration task list:

Configure the number of VSF members (necessary)

Configure the priority of VSF members (optional)

Configure the VSF domain (optional)

Configure the logic VSF port

Bind the physical port to the logic port

Transform the device from independent operation mode to VSF operation mode

Configure the VSF to merge automatically (optional)
