description:

- Specifies resource thresholds or limit requirements at the pool member level.
|

- When you enable one or more limit settings, the system then uses that data to take

members in and out of service.
|
||||
- You can define limits for any or all of the limit settings. However, when a
|
||||
member does not meet the resource threshold limit requirement, the system marks
|
||||
the member as unavailable and directs load-balancing traffic to another resource.
