| Description | 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. |
