An interface queue is modeled as a collection of one or more secondary queues that feed into a device's hardware queue. The hardware queue has a maximum depth set by the MCI tx-queue-limit command or equivalent. The secondary queues (also known as the 'hold queue') have maximum depths set by the hold-queue command or equivalent. This table parallels the ifTable, and indicates the type of queuing in use on the interface, number of queues, and similar parameters." ::= { ciscoQueueObjects 1 } cQIfEntry OBJECT-TYPE SYNTAX CQIfEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "A list of queue attributes for an interface."

First In First Out Queuing implies that the interface always transmits messages in the order that they are received. Priority Queuing sorts messages out by the use of access lists. Messages in a higher priority queue are always sent in preference to messages in a lower priority queue. Custom Queuing sorts messages out by the use of access lists. 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 Queuing sorts messages 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." ::= { cQIfEntry 1 } cQIfTxLimit OBJECT-TYPE SYNTAX Integer32 MAX-ACCESS read-only STATUS current DESCRIPTION "The maximum number of messages placed into the hardware transmission queue. This is a first come first serve queue, fed by the hold queue.
