QoS with Throttling on CERs

I'm trying to configure throttling with QoS on a few CERs.  We have multiple throttling policies applied both inbound and outbound via Layer 2 ACLs.

 

I'm trying to configure an ACL to apply DSCP and Priority based on udp port ranges, but am getting the following error:

 

Error - L4 based ACL is configured on the port.

 

This is what my config looks like:

 

!! Throttling
policy-map Cust-XYZ
 cir 200000000 cbs 209999360
 exit
access-list 401 permit 0050.56xx.xxxx ffff.ffff.ffff any any etype any
access-list 401 permit any 0050.56axx.xxxx ffff.ffff.ffff any etype any
int e 2/4
 rate-limit input access-group 401 policy-map Cust-XYZ
 rate-limit output access-group 401 policy-map Cust-XYZ
 exit

!! QoS
access-list 100 sequence 10 permit udp any any range 45000  50000 dscp-marking 46
access-list 100 sequence 11 permit udp any any range 45000  50000 priority-force 5
access-list 100 sequence 20 permit udp any any range 5060  5061 dscp-marking 46
access-list 100 sequence 21 permit udp any any range 5060  5061 priority-force 5
access-list 100 sequence 30 permit udp any any range 4060  4061 dscp-marking 46
access-list 100 sequence 31 permit udp any any range 4060  4061 priority-force 5
access-list 100 sequence 100 permit ip any any

ip access-group 100 in ethernet 2/4
# Error - L4 based ACL is configured on the port.

Basically, I'm trying to throttle specific devices but also ensure QoS for voice applications.  Is there a better way to get this accomplished?

Re: QoS with Throttling on CERs

Hello,

 

Check if there is a PBR already configured globally on the switch. if a PBR policy is applied globally, inbound ACLs, inbound ACL based rate-limiting or TOS-based QoS cannot be applied to any port on the device.

"show route-map" command will let you know if any route-map (PBR) has been defined.

Hope this helps addressing your concern.
