qos setting

leungcm · ‎06-02-2007

Hi,

we are going to config qos for ds3 cct. the requirement is following:

min b/w: 20M for voip traffic

max b/w: 34M for voip traffic

min b/w: 10M for data traffic (e.g. ms sql data update, monitoring snmp traffic.... etc)

max b/w: 24M for data traffic

we check cisco that there is autoqos feature. how to config it.

if we go for traditional qos, what is the sample config? pls advice

best regards

Hi,

For the AutoQos, pls. go thro. below mentioned link which describes the same with config samples,

http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide09186a0080500b8f.html#wp1057325

But it is better to go for LLQ for more granularity,

http://www.cisco.com/en/US/products/sw/iosswrel/ps1830/products_feature_guide09186a0080087b13.html#wp7313

assign voice traffic with Priority b/w of 34M and assign data traffic using bandwidth command of 10M and police the same with 24M for restricting the maximum bandwidth......

Rate if it does,
