Re: vlan based against port based QOS on CatOS 6500
Each QoS ACL can be applied either to a port or to a VLAN, but there is an additional configuration parameter to take into account; the ACL port type. A port can be configured to be VLAN-based or port-based. The following is a description of the two types of configurations:
A port configured to be VLAN-based will only look to ACL applied to the VLAN to which the port belongs. If there is an ACL attached to the port, the ACL will be ignored for the packet coming in on that port.
If a port belonging to a VLAN is configured as port-based, even if there is an ACL attached to that VLAN, it will not be taken into consideration for the traffic coming in from that port
By default, each port is port-based for the ACL, so if you want to attach an ACL to a VLAN, you need to configure the ports of this VLAN as vlan-based. This can be done by issuing the following command:
set port qos module/port vlan-based
It can also be reverted back to port-based mode by issuing the following command:
