ASR903 QoS marking based on TCP/UDP

[MATTHIAS SCHAERER]

https://www.cisco.com/c/en/us/td/docs/routers/asr903/software/guide/17-1-1/b-qos-guidelines-xe-17-asr900/qos_guidelines_for_rsp3_module.html states that in Cisco IOS XE Release 3.18 the usage of TCP/UDP ports for QoS ACLs does not seem to work. I have not found any other document that would clarify if this works for XE 17.x.x versions. 

Does anyone know if this "3.18" in the above URL is a copy/paste typo or if the usage of QoS ACL with TCP/UDP ports is working for ARR903 in versions 17.x.x?

To answer it myself:

RT01-CORE-ONE#conf t
Enter configuration commands, one per line. End with CNTL/Z.
RT01-CORE-ONE(config)#ip access-list ext ACL_M_QOS_TEST2
RT01-CORE-ONE(config-ext-nacl)# permit tcp any any eq 23
RT01-CORE-ONE(config-ext-nacl)#!
RT01-CORE-ONE(config-ext-nacl)#class-map match-all CM_M_QOS_TEST2
RT01-CORE-ONE(config-cmap)# match access-group name ACL_M_QOS_TEST2
RT01-CORE-ONE(config-cmap)#!
RT01-CORE-ONE(config-cmap)#policy-map PM_M_QOS_TEST2
RT01-CORE-ONE(config-pmap)# class CM_M_QOS_TEST2

A

class-map

based on a standard

access-list

specifying only an IP address (or range) works.

So it seems that the documentation is not 100% accurate.
