The enterprise-specific Destination Class Usage (DCU) Management Information Base (MIB) counts packets from customers by performing a lookup of the IP destination address. DCU makes it possible to track traffic originating from the customer edge and destined for specific prefixes on the provider core router.
The DCU MIB is a subbranch of the jnxMibs branch of the enterprise-specific MIB {enterprise 2636} and has an object identifier of {jnxMIB 6}. The DCU MIB has one branch, jnxDCUs, which contains two tables: jnxDCUsTable and jnxDcuStatsTable. For information about configuring source and destination class usage, see the JUNOS Policy Framework Configuration Guide and JUNOS Network Interfaces Configuration Guide. For a downloadable version of this MIB, see www.juniper.net/techpubs/software/junos/junos94/swconfig-net-mgmt/mib-jnx-dcu.txt.
