A device is a physical or virtual BIG-IP® system. Each device member has a set of unique identification properties that the BIG-IP system generates. In addition to these properties, each BIG-IP device has synchronization and failover connectivity information (IP addresses) that you define. Devices that are members of the trust domain exchange their property and connectivity information through a process known as device discovery.
Each trust domain member contains device connectivity information, that is, the IP addresses that you define on a device for configuration synchronization (ConfigSync), failover, and connection mirroring.
This is the IP address that you want the BIG-IP® system to use when synchronizing configuration objects to the local device.
By default, the system uses the self IP address of VLAN internal. This is the recommended IP address to use for ConfigSync. You can, however, use a different self IP address for ConfigSync.
These are the IP addresses that you want the BIG-IP system to use when another device in the device group fails over to the local device. You can specify two types of addresses: unicast and multicast.
For appliance platforms, specifying two unicast addresses should suffice. For VIPRION® platforms, you should also retain the default multicast address that the BIG-IP system provides.
The recommended unicast addresses for failover are:
The following table lists and describes the properties of a device.
|Device name||The name of the device, such as siterequest.|
|Host name||The host name of the device, such as www.siterequest.com|
|Device address||The IP address for the management port.|
|Serial number||The serial number of the device.|
|Platform MAC address||The MAC address for the management port.|
|Description||A user-created description of the device.|
|Location||The location of the device, such as Seattle, Bldg. 1|
|Contact||The name of the person responsible for this device.|
|Comment||Any user-specified remarks about the device.|
|Status||The status of the device, such as Device is active|
|Time zone||The time zone in which the device resides.|
|Platform ID||An identification for the platform.|
|Platform name||The platform name, such as BIG-IP 8900.|
|Software version||The BIG-IP version number, such as BIG-IP 11.0.0.|
|Active modules||The complete list of active modules, that is, the modules for which the device is licensed.|
A BIG-IP® device can have any status shown in the following table.
|Active||A minimum of one floating traffic group is currently active on the device. This status applies to Sync-Failover device groups only.|
|Forced offline||An administrator has intentionally made the device unavailable for processing traffic.|
|Offline||The device is unavailable for processing traffic.|
|Standby||The device is available for processing traffic, but all traffic groups on the device are in a standby state. This status applies to Sync-Failover device groups only.|
|Unknown||The status of the device is unknown.|
