2.4 Aut o Detect Implementation in VLAN Interface Backup
The interface backup function is used to back up VLAN interfaces by using the auto
detect function. For two VLAN interfaces configured with the same destination device,
you can configure them to be the primary interface and the seco
latter is enabled automatically when the primary fails, so as to ensure the connectivity.
In th is case, the auto detect function is implemented as follows:
In normal situations (that is, when the result of the detecting group is reachable),
the secondary VLAN interface is down and packets are transmitted through the
primary VLAN interface.
When the link between the primary VLAN interface and the destination operates
improperly (that is, the result of the detecting group is unreachable), the system
shuts down the primary VLAN interface and enables the secondary VLAN
interface.
When the link between the primary VLAN interface and the destination recovers
(that is, the re
enables the primary VLAN interface and shuts down the secondary V
interface.
