[SNMP4J] Agent - Dynamic Table - Advice

[Frank Fock]

Hi Jothi,

SNMP does not provide any information beyond the scope
of a single request. So SNMP4J-Agent cannot provide such
info either.

Effective caching of table data can be implemented based
on timeouts for example. You can update the table only
if the last update was done 5 or more seconds ago.

Best regards,
Frank
