policy-maps for proritization

Unanswered Question

We have 6 2620 running 12.3 IOS connecting via point-to-point T1's to a 7204VXR also running 12.3


Each WAN link is being used primarly for SMTP,WWW and SQL (1433) traffic. We would like to implement policy-maps to proritize SQL traffic over everything else.


I am new to this area, so forgive my thoughts, I have a sample syntax that I would like some imput on, goal is to accompalish the above mentioned tasks. Would the config changes(if valid) be made at each router or just the 7204?


Thanks,

Frank


class match-all sql

match ip address 101


class match-all non_sql

match ip address 102


access-list 101 deny tcp any any eq www

access-list 101 deny tcp any any eq smtp

access-list 101 permit ip any any


access-list 102 permit tcp any any eq www

access-list 102 permit tcp any any eq smtp

access-list 102 deny ip any any


policy-map prioritize_sql

class sql

set precendence 5

class nonsql

set precendence 4

Hi,

The configuration works fine. And no need to enter "access-list 102 deny ip any any", because that is already implicit by default.

Setting precedence fields are OK but where and which mechanism will take care of these settings?

I can reccomend using CBWFQ on WAN interfaces. Config is similar but you'll set bandwidth allocated to these classes instead of setting precedence fields. You may have to apply CBWFQ on both sides of the WAN links (on 7000 and 2600). Some helpful links:
