Attach a collector context to an ION device interface to configure the device
interface as a source interface for exporting flow records. You cannot attach a
collector context to more than one interface on the same device, however you can
reuse the collector context for different devices.
If you do not bind a collector context to an interface, the device uses
the controller port by default to establish the connection with the
third-party collector. For platforms that do not have a controller port,
it is mandatory to specify a collector context and bind it to an
interface. Otherwise, the device raises a major alarm
DEVICE_SW_IPFIX_COLLECTORS_DOWN.
The device raises the DEVICE_SW_IPFIX_COLLECTORS_DOWN
major alarm only when it is not able to connect to any of the configured
collectors. There may be different collector configurations on a device that use
different collector contexts. If the device is able to connect to any of the
configured collectors, it will not raise the
DEVICE_SW_IPFIX_COLLECTORS_DOWN alarm.
There are two ways of attaching a collector context to a device.
