I have got a cisco ASA 5525x with OS 9.1(2) and ASDM version 7.2(1). This is the multi-context firewall so we have bundled the interfaces in to port-channel and then we have created sub-interfaces of port-channel which are allocated to different firewall's.
The problem is QOS tab under service policy rules is missing and also I can't configure the command priority-queue 'interface" through CLI.
is this due the sub-interfaces been configured for port-channel?
Any help will be highly appreciated.
yes , QOS is not supported on Sub Interface:-
Note: QoS is not supported on a subinterface, it is only supported on the main interface itself. The configuration of QoS on an interface itself makes all the subinterfaces affected by the QoS
Thanks and Regards,
