Hi,


Is the "queue-list" for QoS?


If so, what is the different between AutoQoS, MQC?

Hello Anita,

queue-list are part of configuration of legacy queueing :


Custom Queueing



these are currently superseaded by LLQ CBWFQ provided by MGC.

there can be application niches for their capability to treat legacy non IP protocols including IPX, AT and others but in a IP only scenario there shouldn't be reasons to use them anymore.

see

RT-TO-CRN-POPE-1(config)#queue-list 1 protocol ?

aarp AppleTalk ARP

appletalk AppleTalk

arp IP ARP

bridge Bridging

bstun Block Serial Tunnel

cdp Cisco Discovery Protocol

compressedtcp Compressed TCP

decnet DECnet

decnet_node DECnet Node

decnet_router-l1 DECnet Router L1

decnet_router-l2 DECnet Router L2

dlsw Data Link Switching

ip IP

ipx Novell IPX

llc2 llc2

pad PAD links

qllc qllc protocol

rsrb Remote Source-Route Bridging

snapshot Snapshot routing support

stun Serial Tunnel


RT-TO-CRN-POPE-1(config)#queue-list 1 protocol



RT-TO-CRN-POPE-1(config)#queue-list 1 ?

default Set custom queue for unspecified datagrams

interface Establish priorities for packets from a named interface

lowest-custom Set lowest number of queue to be treated as custom

protocol priority queueing by protocol

queue Configure parameters for a particular queue

stun Establish priorities for stun packets


if you like look for Custom Queueing Configuration in CCO


Custom Queueing in comparison to CBWFQ lacks elasticity the configured queues are served in round robin taking up to a preconfigured amount of bytes from each queue.

If a queue is empty is processed but doesn't free resources for other traffic types.

Instead this happens in CBWFQ.



Hope to help

Giuseppe
