Config of QoS(Shaping) on Catalyst3850

[YosukeOda]

Hi,

Please tell me config of QoS(Shaping) on Catalyst3850.

Sample config is correct???

I'm sorry, my English is not good.

[Requirement]

  HW:Catalyst3850, IOS:03.06.04.E

  Set QoS(shaping) to a specific traffic.

[Sample config]

Switch(config)# access-list 1 permit 192.168.100.0 0.0.0.255
Switch(config)# class-map match-all Shaping-Match
Switch(config-cmap)# match access-group 1
Switch(config-cmap)# exit

Switch(config-pmap)# policy-map Shaper-Policy
Switch(config-pmap)# class Shaping-Match
Switch(config-pmap-c)# shape average percent 10
Switch(config-pmap-c)# exit

Switch(config-pmap)# class class-default
Switch(config-pmap-c)# shape average percent 90

Switch(config)# interface Gi1/0/23
Switch(config-if)# service-policy output Shaper-Policy
Switch(config-if)# exit

Switch(config)# interface Gi1/0/24
Switch(config-if)# service-policy output Shaper-Policy
Switch(config-if)# exit

<<interface config>>

interface GigabitEthernet1/0/23
 switchport access vlan 10
 switchport mode access
 channel-group 2 mode on
!
interface GigabitEthernet1/0/24
 switchport access vlan 10
 switchport mode access
 channel-group 2 mode on

interface Port-channel2
 switchport access vlan 10
 switchport mode access

Hi!

According to CISCO documentation you can configure the policy in the Etherchannel interface or in the etherchannel members. The configuration seems correct for shaping a specific class to 10% of the total bandwidth.

Hope it helps, best regards!

Hi,

I apply [Sample config] to Catalyst3850.

when i apply service-policy to interfaces, error log is displayed.

This error would be caused by a bug?
