Hi
I have a cisco 3845 with DS-3 connected to serial interface 4/0 it is working good with IOS version 12.4(3g)
interface Serial4/0
description Sprint MPLS DS-3 (NUA-46120459)
bandwidth 44210
ip address 10.0.0.2 255.255.255.252
ip wccp 62 redirect in
ip flow ingress
ip flow egress
ip route-cache flow
ip policy route-map ASA_INTERNET
dsu mode 3
dsu bandwidth 44210
no cdp enable
service-policy output TRFCMGMT

-----------------------------------
but when I do an IOS upgrade to version 15.1(4)M10 the line protocol is down on interface serial 4/0, I don't change any configuration, if I do interface shutdown and after that no shutdown the line protocol is up during few secconds
Could you tell me what command change on this version 15.1(4)M10?
