Traffic help

[mlanio]

I have two routers over 768k frame. There is an exchange server at each end. Sometimes large attachments have to go between the servers and this really bogs down the frame.

I'd like to limit smtp traffic. I've tried traffic shaping and policy-maps, to no avail, though I may not be doing it right. What is the best way to configure the routers to do this?

Hello,

not sure what your policy-map looks like, but this should work:

class-map match-all SMTP

match access-group 101

!

policy-map LIMIT_SMTP

class SMTP

bandwidth percent 30

!

interface serial0/0.1 point-to-point

service-policy input LIMIT_SMTP

!

access-list 101 permit tcp any any eq smtp

Can you try and configure this ? Your policy and class-map options might differ, depending on your IOS version and platform...

Regards,

Georg

Should the bandwidth statement be bandwidth 768 on the serial sub interface?

[mlanio]

Nope didn't work. I have 12.2 ios. Here's my statements on both routers:

2621

class-map match-all Mail

match access-group 102

policy-map Mail

class Mail

bandwidth percent 30

interface Serial0/0.12 point-to-point

description Connection to Arkansas

bandwidth 768

ip address 192.168.254.6 255.255.255.252

no ip route-cache

no ip mroute-cache

frame-relay interface-dlci 45

class Mail

map-class frame-relay Mail

frame-relay cir 768000

frame-relay bc 1900

frame-relay be 0

frame-relay mincir 768000

service-policy output Mail

access-list 102 permit tcp any eq smtp any eq smtp

Other router is basically the same.

It wouldn't accept the service policy input statement..

Did you set the " service-poolicy input Mail " at your interface ?

Your access list is wrong as no client allso sends from the smtp port.

This should be "access-list 102 permit tcp any any eq smtp"

It realy should work as the accepting of the previous and shown commands don't make any sense if not applyable to any interface.

I changed the Access-list but it didn't make a difference. as for the service-policy statement, it doesn't seem to take. The IOS accepts it as without error, but a show run doesn't show the statement under the sub-interface...
