BigIP F5 LTM - Administrative States
Via the use of administrative states, the administrator has the power to gracefully select a pool members state.
There are 3 administrative states:
Enabled - This is the default state. All connection types are passed to the pool member and the monitor continues to determine the state of the member.
Disabled - Only new connections from returning clients within the defined timeout period (via the persistence record) are allowed.
Forced Offline - This state is administratively set. No additional connections are allowed and monitor checks are not performed.
Note : The states Forced Offline and Disabled only differ when persistence is configured.
Changing the State
The state can be configure via :
- Virtual Server - Go to the 'Virtual Server | General Properties | State' then select either Enable/Disabled.
- Pool Member - Go to 'Local traffic | Pools | Members | Select member' and then select either Enable/Disabled/Forced Offline.
When an administrative state is :
Disabled the monitor status icon is black but the monitor status icon shape is retrained.
Forced Offline the icon consists of a black diamond.
Note : To distinguish between Disabled and Forced Offline hover the mouse over the status icon.
