Cisco 3650 L3 Switch: Can't Change Port Speed from GigE to 100

[BashedRoot]

Usually works fine, but I was messing around with policy-map settings as this server is skyrocketing in bandwidth and need to tame it a little. Problem is, it won't let me revert the speed from 1000 to 100.

My method:

Cisco3650#conf t
Cisco3650(config)#policy-map speed25
Cisco3650(config-pmap)#class class-default 
Cisco3650(config-pmap-c)#bandwidth percent 25
Cisco3650(config-pmap-c)#exit
Cisco3650(config-pmap)#exit
Cisco3650(config)#int gi2/0/19
Cisco3650(config-if)#service-policy output speed25
Cisco3650(config-if)#do sh run int gi2/0/19
Cisco3650(config-if)#do sh policy-map speed25

Cisco3650#sh platform qos policies port
Loc Interface          IIF-ID             Dir Policy             State          
--- ------------------ ------------------ --- ------------------ ---------------
L:0 Gi2/0/19           0x01088b0000000032 OUT speed25               INSTALLED IN HW


Cisco3650#conf t
Cisco3650(config)#int gi2/0/19
Cisco3650(config-if)#no service-policy output speed25
Cisco3650(config-if)#exit
Cisco3650(config)#no policy-map speed25
Cisco3650(config)#do sh policy-map speed25
Cisco3650(config)#exit
Cisco3650#sh platform qos policies port
 Policy: None in the list 
Cisco3650#show run interface gi2/0/19
Cisco3650#show policy-map speed25

Also, this command doesn't work?

Switch2#sh platform qos policies port

Still stuck at full GigE

Hi,

Not sure what you are trying to achieve? Do you want to set the interface to 100Mb/full duplex or  rate limit traffic? Are the switches running the same IOS version?

Thanks

I'm trying to rate limit based on the 100Mbit port speed, 25% usage (basically 25Mbps speed).

Same version on each switch.
