Description
Create and name a link protection subgroup.
Link protection subgroups allow you to provide link protection to a collection of Ethernet links within a link aggregation group (LAG). If you need to provide link protection to a single link in a LAG, you do not need to configure link protection subgroups.
A link protection subgroup includes multiple links within the LAG. If one link in the primary link protection subgroup fails, traffic is forwarded over the links in the backup link protection subgroup.
Links within the LAG are added to the link protection subgroup
using the link-protection-sub-group statement in the [edit interfaces interface-name ether-options
802.3ad] hierarchy.
