Custom Queuing

Custom Queuing

With custom queuing, abstracts is placed into one of up to 16 altered queues, authentic by queue

number. These queues are emptied on a austere rotational basis. Once a queue’s address threshold

has been reached, the abutting chain is serviced, irrespective of whether the accepted chain still

has packets in it.

Configuration options accessible to the ambassador accommodate how to ascertain the traffic,

what chain to abode the cartage into, how ample anniversary chain should be, and how ample each

queue’s account beginning should be.

To ascertain the cartage for a accurate custom queue, use the queue-list all-around command:

Terry_3550(config)#queue-list ?

<1-16> Chain account number

Terry_3550(config)#queue-list 1 ?

default Set custom chain for bearding datagrams

interface Establish priorities for packets from a called interface

lowest-custom Set everyman cardinal of chain to be advised as custom

protocol Antecedence queueing by protocol

queue Configure ambit for a accurate queue

stun Establish priorities for amaze packets

Terry_3550(config)#queue-l 1 interface ?

Async Async interface

BVI Bridge-Group Virtual Interface

Dialer Dialer interface

FastEthernet FastEthernet IEEE 802.3

Multilink Multilink-group interface

Terry_3550(config)#queue-l 1 interface fastEthernet 0/12 ?

<0-16> chain number

Terry_3550(config)#queue-l 1 interface fastEthernet 0/12 1

Terry_3550(config)#queue-l 1 interface fastEthernet 0/13 2

Terry_3550(config)#queue-l 1 interface fastEthernet 0/14 2

Terry_3550(config)#^Z

To ascertain the best chain admeasurement for a accurate custom queue, use the queue-list

queue-limit queue-number byte-count all-around command:

Terry_3550(config)#queue-list 1 ?

default Set custom chain for bearding datagrams

interface Establish priorities for packets from a called interface

lowest-custom Set everyman cardinal of chain to be advised as custom

protocol Antecedence queueing by protocol

queue Configure ambit for a accurate queue

stun Establish priorities for amaze packets

Terry_3550(config)#queue-list 1 chain 1 ?

byte-count Specify admeasurement in bytes of a accurate queue

limit Set chain admission absolute of a accurate queue

Terry_3550(config)#queue-list 1 chain 1 byte-count ?

<1-16777215> Admeasurement in bytes

Terry_3550(config)#queue-list 1 chain 1 byte-count 10000 ?

limit Set chain admission absolute of a accurate queue

Terry_3550(config)#queue-list 1 chain 1 byte-count 10000 absolute ?

<0-32767> Cardinal of chain entries

Terry_3550(config)#queue-list 1 chain 1 byte-count 10000 absolute 10

Terry_3550(config)#^Z

Allocating the antecedence chain to a accurate approachable interface is accomplished application the customqueue-

list custom-queue interface command:

Terry_3550(config)#int fastEthernet 0/1

Terry_3550(config-if)#custom-queue-list 1

Terry_3550(config)#^Z

The afterward agreement uses admission account 101 to abode Telnet cartage amid any two hosts

into chain 1, uses admission account 102 to abode web cartage amid any two hosts into chain 2, and

places all added IP cartage into chain 3, while CDP cartage is placed into chain 4. Changing the

queue sizes has the aftereffect of “fairly” allocating chain amplitude to traffic:

Terry_3550(config)#queue-list 1 agreement ip 1 account 101

Terry_3550(config)#queue-list 1 agreement ip 2 account 102

Terry_3550(config)#queue-list 1 agreement ip 3

Terry_3550(config)#queue-list 1 agreement cdp 4

Terry_3550(config)#access-list 101 admittance tcp any any eq telnet

Terry_3550(config)#access-list 102 admittance tcp any any eq www

Terry_3550(config)#queue-list 1 chain 1 byte-count 2000 absolute 25

Terry_3550(config)#queue-list 1 chain 2 byte-count 5000 absolute 20

Terry_3550(config)#queue-list 1 chain 3 byte-count 10000 absolute 10

Terry_3550(config)#queue-list 1 chain 4 byte-count 1000 absolute 5

Terry_3550(config)#^Z

The 16 queues are all configurable, but you alone charge to configure as abounding as

you charge or appetite to. A abstracted 17th chain is created by the router for use by

systems traffic. This chain is not configurable.
