Hi
After upgrade to 15.3(3)S and on one switch with 15.3(1)S1 i got error

Hi startx001 and LCC Data Networks,
This issue is related with TCAM resource exhaustion:
Issue the following command:
sh platform tcam utilization qos and see if you still have available entries to be used:
XXXXXXXXXX#sh platform tcam utilization qos
Nile Tcam Utilization per Application & Region:
ES == Entry size == Number of 80 bit TCAM words
==================================================================
App/Region Start Num Avail ES Used Range Num Used
==================================================================
QOS 36864 4096 2
nile0 1802
nile1 1376
I had to ajdust QoS profiles to free space.
Hope this help you.

Hi startx001, hope you will be fine.
Did you a find a solution for this issue?
I'm facing same problem

This issue seems to arise when matching any vlan (match vlan 1-4094) on a class-map. It does possibly sound like a bug, but I've now ameneded my class-map to match all traffic based on protocol instead - this seems like it might work OK.
Class-map match-any class1
Match protocol ip
Match protocol ipv6
Match protocol arp
Match protocol cdp

Also got the same issue.

Could you please share the below output:
- show platform tcam utilization all
- show platform tcam utilization qos
- show platform qos label structs
- show sdm prefer current
- show run
Please attach all the above outputs in a file. Also, could you please let me know how many vlans are there on the switch and if the service-policy is being applied on a trunk port.
Thanks

I've now got a TAC case open, and the TAC engineer has managed to replicate the fault. I'm waiting to hear back. I've also attached the outputs here for information.
I started with a completely blank config, and applied the following to replicate the error:

match dscp ef
class-map match-any class1
