Usage Guidelines

By default, the device does not have link-group monitor groups.

The link-group function binds the status of several interfaces to form a logical group. If any interface in a link-group fails, other interfaces in the link-group are changed to Down. To associate the interface status of different link-groups, configure a link-group monitor group. When configuring a link-group monitor group, properly plan the relationship between sub-groups and link-groups to achieve the association of interface status in different link-groups. The relationships between the link-group monitor group, sub-groups in the link-group monitor group, link-groups, and interfaces in the link-groups are as follows:

A link-group can be added to only one sub-group of a link-group monitor group.
Link-groups in a sub-group of a link-group monitor group are independent of each other and do not affect each other.
Different sub-groups in a link-group monitor group affect each other only in the following situation: The device forcibly changes all interfaces in link-groups of other sub-groups to Down only when the state of all link-groups in a sub-group is fault.
Different link-group monitor groups are independent of each other and do not affect each other.

The link-group monitor group can be created only in the public system but not in virtual systems. If an interface in a virtual system needs to be associated with an interface in the public system, run the link-group public link-group-id command to add the virtual system interface to the link-group of the public system.

Example

# Create link-group monitor group test.

<sysname> system-view
[sysname] link-group-monitor name test
[sysname-link-group-monitor-test]
