Convert IP precedence 6 on inbound interface to IP precedence 5 on outbound

Any Help would be appreciated. My provider only takes IP precendence 5 for VoIP. I'm trying to figure out how to convert my VoIP packet on my router from 6 inbound Fast ethernet to 5 on outbound Serial Interface.

How are the packets geeting set to IPP 6? Normally 6 is only used for router originated traffic like route updates. Voice ports will use IPP 5 (DSCP EF) by default for RTP traffic.

You can use an inbound service policy on the FE to re-mark packets.

Hi,

You can do something like te following:

class-map prec6

match ip precedence 6

!

policy-map prec6to5

class-map prec6

set ip precedence 5

!

interface FastEthernet0

service-policy input prec6to5

Hope that helps - pls rate the post if it does.

IPP6 is being set by the EU's 3Com phone system. I don't know whey but that is what the customer requested. I have figured out how to address. Thanks for all the help.
