QoS for Cisco IP phone & MS Teams

chris.jinks
Level 1
Level 1

Hi,

 

I'm looking at a QoS policy for our C1000 switches, In short, i need our Cisco phones trusted and also our workstations as we have configured a group policy that sets the DSCP markings for teams.exe to EF (46)  

 

My question is which Auto QoS config do i use;

Trust? as i will want to trust the DSCP marking for Teams and that of the Cisco IP phone

VoIP?  because they are all voice over IP (we have cisco-phones and some softphones)

Video? I will also be setting the DSCP marking for teams video as well (we don't use any Cisco video application)

 

worth noting we don't have any control of the router, only the switch to apply config, unless absolutely required (customer-owned, provider-managed) though i do know they have the below config 

 

class-map match-any ce_ef_output
match dscp cs5 ef
class-map match-any ce_mgmt_bundled_output
match access-group 199
class-map match-any ce_af3_output
match dscp cs3 af31 af32 af33
class-map match-any ce_af3_input
match dscp cs3 af31 af32 af33
class-map match-any ce_ef_input
match dscp cs5 ef

Hi, use video and it will take care of both video and audio. Trust will
reset the dscp markings for teams because it relies on cdp to trust
endpoints
