Cisco C9300 strict priority not allowed with bandwith

[Borja Plaza Simo]

Hi,

I would like to configure the following policy-map on a Cisco C9300 CAT9K_IOSXE 17.03.04:

class-map match-any SERV-CRITICOS
match ip precedence 3 4
class-map match-any SERV-TREAL
match ip precedence 5 7

policy-map PM-QOS-SALIDA
class SERV-TREAL
priority percent 60
class SERV-CRITICOS
bandwidth percent 40

But I get the following error:

Strict priority or priority level cannot co-exist with bandwidth kbps/percent in any other class.

Could someone help me with this configuration?

Regards,

Hello  Borja Plaza Simo

Try this:

class-map match-any SERV-CRITICOS
match ip precedence 3 4
class-map match-any SERV-TREAL
match ip precedence 5 7

policy-map PM-QOS-SALIDA
class SERV-TREAL
priority level 1 percent 60  < ------ 
class SERV-CRITICOS
bandwidth percent 40

Each port supports eight egress queues, of which two can be given a priority.

You use the priority level policy class-map command to configure the priority for two classes. One of the classes has to be configured with a priority queue level 1, and the other class has to be configured with a priority queue level 2. Packets on these two queues are subjected to less latency with respect to other queues.

Only one strict priority or a priority with levels is allowed in one policy map. Multiple priorities with the same priority levels without kbps/percent are allowed in a policy map only if all of them are configured with police.
