Each entry represents an active SDP binding loopback. The SDP binding is placed in loopback by row creation and is removed by row destruction. Rows in table sdpBindPwLoopbackTable are created and destroyed by SNMP set operations on the object sdpBindPwLoopbackRowStatus. Rows in table sdpBindPwLoopbackTable may be destroyed by the system when the associated SDP binding has been deleted. A maximum of 64 rows may be created. Rows are kept in volatile storage and lost upon a system reboot.
