3640 priotize traffic 1

[jvandebogert]

I have a 3640 with IOS 12.3(1a). How would I prioritize traffic. For example let say someone is downloading something and it takes up all the bandwidth. However I want email to go through so traffic from ports 110 and 25 I want to set higher priority. Could someone help me with this?

Well can implement something like fair queuing on a serial interface to keep any one person from hogging the bandwidth . Everyone gets an equal share .

but there is no way to prioritize one kind of traffic over another?

Example on priority lists where SMTP has higher priority than everythinh else:


Router(config)#access-list 120 permit ip 192.168.1.0 0.0.0.255 any eq smtp
Router(config)#access-list 110 permit ip 192.168.1.0 0.0.0.255 any
Router(config)#int e0
Router(config-if)#ip access-group 110 in
Router(config-if)#exit
Router(config)#priority-list 1 protocol ip high list 120
Router(config)#priority-list 1 protocol ip normal list 110
Router(config)#int e0
Router(config-if)#priority-group 1


I think you'll get the idea...
