Interpret the Enterprise-Specific Source Class Usage MIB

The source class usage (SCU) MIB counts packets sent to customers by performing a lookup on the IP source address and the IP destination address. SCU makes it possible to track traffic originating from specific prefixes on the provider core and destined for specific prefixes on the customer edge.

The SCU MIB is an object of the jnxMibs branch of the enterprise-specific MIB
{enterprise 2636} and has an object identifier of {jnxMIB 16}. The SCU MIB includes one object, jnxScuStats, which has an object identifier of {jnxScu 1}. For information about configuring source and destination class usage, see the JUNOS Internet Software Configuration Guide: Policy Framework and JUNOS Internet Software Configuration Guide: Interfaces and Class of Service. For a downloadable version of this MIB, see www.juniper.net/techpubs/software
