I have an IP-Base universal image on a Cisco 891 and a Cisco 4321, version 15.6 in the 891 and version 16.6.7 in the 4321.
¿Do I need to buy any special license to enable Layer3-Layer4 class-maps, match protocol http url, policy-maps, service-policy out on interfaces and QoS in general WITHOUT advanced NBAR2?
