QoS 3750ME

Is there any chance I can configure QoS on fastethernet port to reserve bandwith for specific networks?

I tried this configuration:

Policy Map pm-voice

Class cl-voice

bandwidth 30 (kbps)

However, I can not assign this policy map to fastethernet interface

"Bandwidthis only supported in a hierarchical policy on ES interfaces"

Any ideas?

Re: QoS 3750ME

Fuad,

The error message is self-explanatory, you can only configure hierarchical QoS on ES (Enhanced Services) Ports.

The ES Ports are the SFP uplinks on the switch, the rest of ports are regular ports with limited QoS services.

More information on the 3750ME and ES Ports can be found at:

Re: QoS 3750ME

The following Policy-maps donot have a default class configured.

pm-voice The class-default class is used to classify traffic that does not fall into one of the defined classes. The class-default class is predefined when the policy map created, but must be configured. If no default class is configured, then by default the traffic that does not match any of the configured classes is flow classified and given best-effort treatment.

TRY THIS: To configure the class-default class to use tail drop, use the 'bandwitdth' policy-map class configuration command to configure policy for the default class.

Re: QoS 3750ME

Sorry, I didnt really understand. Can you please explain again? Do I have to add a default class to the existent policy map?
