I would say they are the same - I would suspect that NBAR would use more resources but I might be wrong
Remember that the solution guide shows one way of solving an issue, as long as you meet the requirements you would receive the points. The DSG may show the ACL solution/s more times than not as this would be considered at times (in my opinion) more difficult than NBAR HTH -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of John C. Durnin Sent: February-19-11 9:11 AM To: [email protected] Subject: [OSL | CCIE_RS] MQC matching I've been trudging through the QOS portion of the labs and am finding in the Solutions Guide that a lot of the times the matching is done by ACL's equaling protocols and not matching the protocols using nbar. I wanted to make sure that I'm understanding this correctly. Are the following 2 examples the same? Example 1 Access-list 101 permit tcp any any eq smtp Access-list 101 permit tcp any eq smtp any Class-map match-all email Match access-group 101 Example 2 Class-map match-any email Match protocol smtp If these 2 examples are doing the same thing, what are the pro's/con's of using one over the other? I'm just wanting to make sure that this is just another way to get from point A to point B and I'm not missing some bigger picture. _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
