Statistical Information for VLAN-Group Policies and Classes

The router displays packet statistics for VLAN-group policies using the modular QoS command-line
interface (MQC) show commands. Statistical information displayed for VLAN groups represents the
aggregate traffic of all of the subinterface members of the specific VLAN group.
The router updates match-VLAN filter statistics only for the aggregate traffic through the VLAN groups.
