5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide Note: The mark possibilities for policing include CoS, IP DSCP, and IP Precedence. While the latter two are only meaningful for IP packet types, CoS marking is allowed for both IP and non-IP packets, since it updates the 802.1p user priority field contained in the VLAN tag of the layer 2 packet header. 12-17 diffserv This command sets the DiffServ operational mode to active.

Command Mode Global Config DiffServ Class Commands Use the DiffServ class commands to define traffic classification. To classify traffic, you specify Behavior Aggregate (BA), based on DSCP and Multi-Field (MF) classes of traffic (name, match criteria) This set of commands consists of class creation/deletion and matching, with the class match commands specifying Layer 3, Layer 2, and general match criteria. The class match criteria are also known as class rules, with a class definition consisting of one or more rules to identify the traffic that belongs to the class. Note: Once you create a class match criterion for a class, you cannot change or delete the criterion. To change or delete a class match criterion, you must delete and recreate the entire class. The CLI command root is class-map. 12-18 class-map This command defines a DiffServ class of type match-all. When used without any match condition, this command enters the class-map mode. The class-map-name is a case sensitive alphanumeric string from 1 to 31 characters uniquely identifying an existing DiffServ class. Note: The class-map-name 'default' is reserved and must not be used. The class type of match-all indicates all of the individual match conditions must be true for a packet to be considered a member of the class.This command may be used without specifying a class type to enter the Class-Map Config mode for an existing DiffServ class. 1156
