       I've been looking everywhere for a definitive doc on Ingress QOS
service-policy support.  All the docs I've found on Cisco's site seem to
mentions IOS-XE 3, but seem to be ASR1K specific.  Can't seem to find any
etherchannel docs for ISR4K specifically.  Upon trying to apply an ingress
policy on a 4K port channel int (main int has IP address, no subints), the
error message "service-policy input COS-IN not supported on this target" is
displayed. It's a 4451-X running 3.13.3. Port channel config looks like
interface Port-channel1 description HJ102530 Customer LAN ip address
10.x.y.2 no ip proxy-arp ip flow monitor netflow input ip
flow monitor netflow output ip tcp adjust-mss 1432 no negotiation auto

Now I did find in this doc:

reference to these commands: port-channel load-balancing vlan-manual
or load-balancing
vlan (on interface)

This router is ISP-owned so I'd like to find out the definitive answer
prior to having them try something.  Anyone know the real deal with QOS and

Hi all

Can someone give me a hint about how to do policy based routing on PE node
in and MPLS network.
We have to change our internet access to a new service provider, and we
would like to do it as smoothly as possible.
The problem is that our old firewalls are located in an mpls vpn and all
ingress interfaces is tag switched.
Is there a way to do PBR on an incoming mpls interface.
Any suggestions would be appreciated
The setup is like the drawing

I was just working with a customer that has a 3850 - 24 port that
continually sends goodbye tlv every 80 seconds

He also has a 3850 48 port that works fine

The 3850 24 port can NOT ping at all

The 3850 48 port can ping and gets responses from all the eigrp
neighbors on the vlan

Router eigrp 1 configs are same
