SNMP Private MIB Information Refresh
In the Octel 200/300, the LAN card maintains a local copy of private MIB information. The LAN card
updates this copy with new information from the CPU at intervals of 2 minutes
When the SNMP manager queries the LAN card for private MIB information, the LAN card responds
immediately from its local copy. The MIB information sent may not reflect changes that have occurred in
the last two minutes, until the LAN card refreshes its copy from the CPU.
