Hello,
can someone point me out how to limit traffic to specific port on a C6k plattform?
Assuming there is a GE port. Traffic go through this port with destination to port 53 (DNS)
should be limiting to a maximum of 100 Mbps, all other traffic should be normally burstable
to full Gig. Thanks.

You will need to configure qos, if you can provide more details of the network and your config we can help you with this

Hello,
thanks for your answer.
It is a Catalyst 6509-E with SUP720-3BXL and WS-X6724-SFP (with WS-F6700-DFC3BXL) running 15.1(1)SY1.
QoS is not enabled yet. Here is the config of the port:
! interface GigabitEthernet8/1 switchport switchport access vlan 700 switchport mode access no cdp enable !interface Vlan700 ip address 192.168.150.102 255.255.255.248 ip verify unicast reverse-path 150 ipv6 nd ra suppress !access-list 150 permit ip any any!
Thanks,
Thomas

I've created two configs. Would one of these fit my requirements to limit inbound traffic on port 8/1 to a maximum
of 100 Mbps? (10% of the available port bandwidth)
