ccmtrCollectionSrcIfIndex
Cisco Cable Metering Collection Source If Index
1.3.6.1.4.1.9.9.424.1.1.9
The ifIndex of the interface which will be used as the source interface for the billing packets. When ccmtrCollectionType is 'local', the IP address of this source interface will be used as the CMTS IP address in the billing packets. When ccmtrCollectionType is 'stream', the source IP address of the billing packets as well as the CMTS IP address in billing packets will be changed to the IP address of this interface. In both the cases, the mac address of the source interface would be used in the billing packet headers. A value of zero on this object indicates that the source interface is not specifically configured and the system will determine the source interface to use for billing packets dynamically. This object can only be set when ccmtrCollectionType is either 'local' or 'stream'.
