Queue Type (cQIfQType)

Type of queuing used in the Hold Queue.

Queuing Types | Description
First In First Out | Transmits messages in the order that they are received.
Priority | Messages in a higher priority queue are sent before messages in a lower priority queue.
Custom | Messages are sorted according to access lists.
Sub-queues | Sub-queues are selected in round robin order as either the sub-queue is drained or a given number of octets is moved from the sub-queue to the transmission queue.
Weighted Fair | Messages are sorted by 'conversation', which is source-destination pair of addresses and sockets or ports, as defined by the network layer protocol. Messages are removed from queues in a sequence that gives each conversation a proportion of the available bandwidth.

Queue Limit (cQIfTxLimit)

The maximum number of messages placed into the hardware transmission queue. This is a first come first serve queue, fed by the hold queue. If the hold queue contains information, this queue is presumably full.

No of Sub Queues (cQIfSubqueues)

The number of sub-queues of which the hold queue is built. This is a constant for each value of cQIfQType.
