QOS Conversion in IOS XE

NETAD

Level 4

Hello, can you assist me in converting this QoS config to a compatible IOS XE config. Thank you very much.

Hello,

 

there is no 1 to 1 conversion. Since you are using EtherChannel interfaces, you cannot use auto qos either.

 

Below is the converted auto qos output for 'trust dscp', which you can enter manually and apply the service-policy outbound on your interfaces:

 

class-map match-any PRIORITY_QUEUE_CLASS
match dscp cs4 cs5 ef
match cos 5

!

class-map match-any CONTROL_MGMT_QUEUE_CLASS
match dscp cs3 cs6 cs7
match cos 3

!

class-map match-any MULTIMEDIA_CONF_QUEUE_CLASS
match dscp af41 af42 af43
match cos 4

!

class-map match-any TRANS_DATA_QUEUE_CLASS
match dscp af21 af22 af23
match cos 2

class-map match-any BULK_DATA_QUEUE_CLASS
match dscp af11 af12 af13
match cos 1
