cefLMPrefixSpinLock 1.3.6.1.4.1.9.9.492.1.1.3

An advisory lock used to allow cooperating SNMP Command Generator applications to coordinate their use of the Set operation in creating Longest Match Prefix Entries in cefLMPrefixTable. When creating a new longest prefix match entry, the value of cefLMPrefixSpinLock should be retrieved. The destination address should be determined to be unique by the SNMP Command Generator application by consulting the cefLMPrefixTable. Finally, the longest prefix entry may be created (Set), including the advisory lock. If another SNMP Command Generator application has altered the longest prefix entry in the meantime, then the spin lock's value will have changed, and so this creation will fail because it will specify the wrong value for the spin lock. Since this is an advisory lock, the use of this lock is not enforced, but not using this lock may lead to conflict with the another SNMP command responder application which may also be acting on the cefLMPrefixTable.
