[Sysname-Vlan-interface3] mad arp enable mad bfd enable Syntax mad bfd enable View undo mad bfd enable VLAN interface view Default level 3: Manage level Parameters None Description Use mad bfd enable to enable BFD MAD. Use undo mad bfd enable to disable BFD MAD. By default, BFD MAD is disabled. BFD MAD uses the BFD protocol for detecting multi-active collisions, and can work with or without intermediate devices. When you configure BFD MAD, follow these guidelines: • You cannot enable BFD MAD detection on VLAN-interface 1. • Do not use the BFD MAD VLAN for any other purpose. No Layer 2 or Layer 3 features, including ARP and LACP, can work on the BFD MAD-enabled VLAN interface or any port in the VLAN. If you configure any other feature on the VLAN, neither the configured feature nor the BFD MAD function can work correctly. • Do not enable the spanning tree function on any port in a BFD MAD VLAN. The MAD function is mutually exclusive with the spanning tree function. • Do not bind a BFD MAD-enabled VLAN interface to any VPN. The MAD function is mutually exclusive with VPN. • To avoid anomalies, do not assign the BFD MAD-enabled VLAN interface a common IP address, for example, an IP address configured with the ip address command or a VRRP virtual IP address. • If an intermediate device is used, assign the ports of BFD MAD links to the BFD MAD VLAN on the device. Related commands: mad ip address. Examples # Enable BFD MAD on VLAN-interface 3. system-view [Sysname] interface vlan-interface 3 [Sysname-Vlan-interface3] mad bfd enable 17
