public final class IfXTable
extends SnmpTable<IfXTableEntry>

The IfXTable uses a SnmpSession to collect the entries in the remote agent's interface extensions table. It implements the SnmpHandler to receive notifications and handle errors associated with the data collection. Data is collected using a series of GETNEXT PDU request to walk multiple parts of the interface table at once. The number of SNMP packets should not exceed the number of interface + 1, assuming no lost packets or error conditions occur.
