cdcDNSServerNextAvailIndex
Cisco DNS Client DNS Server Next Available Index
1.3.6.1.4.1.9.9.436.1.1.3
This object contains the next available value for the object 'cdcDNSServerIndex'. If all values are exhausted, then this object will contain a 0 value. A management application should read this object, get the (non-zero) value and use same for creating an entry in the 'cdcDNSServerTable'. If two network management applications read this object at the same time and try to create an entry in the 'cdcDNSServerTable', only one of them will succeed. The network management application which failed, will need to re-read this object and try the SET again.
