We planned to configure QOS in our ASA. Decided to go for priority queue, but the problem is, asa is cofigured with subinterfaces. If i apply the command priority-queue physica interface name, then this will take care of subinterfaces configured under the physical interface?
Is there any way we can use priority queue for subinterface links.
As per your query,QoS is not supported on a subinterface, only on the main interface itself. If you configure QoS on an interface itself, all the sub-interfaces are also affected by the QoS. Here is the doc for it:
Hope this helps
Hi Guys -
When people choose to configure subinterfaces on an ASA, as I generally do, they commonly don't configure the physical interface at all -- no NAMEIF, no IP address, etc. In this case you'll need to put a 'NAMEIF' on the physical interface in order to apply the priority queue, which will then be inherited by the subinterfaces as described above.
Note that the service-policy (that specifies "priority" queueing for some traffic) is still applied to the subinterface.
