    I have a Cisco 877 and would like to give all WAN traffic going through
    port 80, 110, and 25 priority.

    I need some advice on what type of QoS to apply and maybe some tips on
    how to apply it.

    Using the MQC:

    Router(config)#class-map HIGHPRIORITY
    match http
    match pop3
    match smtp
    bandwidth X

    X = the total % or in kbs of the bandwidth you want to allow for your

    then, just go under the WAN interface and do:

    Router(config-if)#service-policy output HIGHPRIORITY_POLICY

    That should take care of it. That will give priority to traffic going
    outbound on your WAN interface. If you have services hosted within your
    network, then you would change that to inbound.

    u can try this

    !match traffic
    access-list 101 permit tcp any any eq 110
    access-list 101 permit tcp any any eq 25
    access-list 101 permit tcp any any eq 80

    class-map match-any high-priority-class
    match access-group 101

    policy-map high-priority-policy
    class high-priority-class
    set ip dscp af31

    !apply to interface
    interface faxx
    service-policy output high-priority-policy
