A DSC® device is a physical or virtual BIG-IP® system that is also:
The definition of what constitutes a device group member varies depending on the platform type:
|For this BIG-IP® platform....||Each device group member is...|
|An appliance model||An individual appliance|
|An appliance model, provisioned for vCMP®||A vCMP guest running on an appliance. Each guest as a device group member must reside on a separate appliance.|
|VIPRION® chassis with blades (bare-metal)||An individual chassis with blades|
|VIPRION system with blades, provisioned for vCMP||A vCMP guest running on a chassis. Each guest as a device group member must reside on a separate chassis.|
Each device in a device group must contain device connectivity information, that is, the IP addresses that you define on the device for configuration synchronization (config sync), failover, and connection mirroring.
This is the IP address that you want other devices 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 config sync. You can, however, use a different self IP address for config sync.
These are the IP addresses that you want another device to use when failing 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:
From the local BIG-IP® device, you can view or configure the properties of any device within the local trust domain, including the local device.
The following table lists and describes the properties of a device.
|Name||The name of the device, such as siterequest.|
|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.|
|Hostname||The host name of the device, such as www.siterequest.com|
|IP address||The IP address for the management port.|
|Serial Number||The serial number of the device.|
|MAC Address||The MAC address for the management port.|
|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.|
|Status||The status of the device, such as Device is active|
|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.|
At all times, the BIG-IP® system displays a specific status for each device in a device group.
|Active||The device is available and is processing traffic on the network. If the device is a member of a Sync-Failover device group, this status indicates that at least one traffic group is active on the device.|
|Forced Offline||An authorized user has intentionally taken the device offline, usually for maintenance purposes.|
|Offline||The device is offline for a reason other than being forced offline by an authorized user.|
|Standby||The device is available but is not processing traffic on the network. This applies to devices in a Sync-Failover device group only, and all traffic groups on the device are Standby traffic groups only.|
|Unknown/Not Watched||The BIG-IP system cannot determine the status of the device. This status usually occurs when the device has not yet joined a device group.|
