QoS in Layer 3 port 4500 SUP7-E

[khernandezruiz]

Hi everyone,

I want to know if is it possible to configure QoS on a 4500 Sup7 on a Layer 3 routed port like the following example (Similar to CBWFQ on IOS Router)?

Switch(config)# configure terminal
Switch(config)# policy-map policy11


Switch(config-pmap)# class prec1


Switch(config-pmap-c)# bandwidth percent 30


Switch(config-pmap-c)# exit


Switch(config-pmap)# class prec2


Switch(config-pmap-c)# bandwidth percent 20


Switch(config-pmap-c)# exit


Switch(config-pmap)# class prec3


Switch(config-pmap-c)# bandwidth percent 10


Switch(config-pmap-c)# exit


Switch(config-pmap)# exit


Switch(config)# interface gigabitethernet1/1
Switch(config)# no switchport

Switch(config)# ip address 10.1.1.1 255.255.255.252
Switch(config)# service-policy output policy1


My doubt is because the following sentence:
Restrictions for Applying a QoS Service Policy

Traffic marking can be configured on an interface, a VLAN, or a port and VLAN. An interface can be a Layer 2 access port, a Layer 2 switch trunk, a Layer 3 routed port, or an EtherChannel. A policy is attached to a VLAN using the vlan configuration mode.

Hello, you will be able do do this, the SUP7-E has full capabilities of this.

The restrictions section is a bit misleading, because it tells you what it CAN do.
If any limitations, it may be on the line card itself, but probably not.
I have tested QoS on a 4506 with SUP7E and it works perfectly.

Hope this helps

Thank you,

Then is possible, so I won't need to use in a SVI way with access port. I want to make it simple.

Thanks for the advice.

Kind regards,

Yes you are correct. You can apply to a physical interface or a vlan interface too.

Hope this helps
