All Implemented Interfaces:

Collectable

public final class IfTable
extends SnmpTable<IfTableEntry>

The IfTable uses a SnmpSession to collect the entries in the remote agent's interface 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.

Addition by Jon Whetzel

IfTable has an extra class variable for the SNMP version setting. If this is set for SNMPv2, then a GETBULK command will be used for retrieving the necessary data. Otherwise, the method will resort to its previous implementation with GETNEXT commands.

Constructor Detail

IfTable

public IfTable(InetAddress address)

Constructs an IfTable object that is used to collect the interface elements from the remote agent. Once all the interfaces are collected, or there is an error in the collection the signaler object is notified to inform other threads.
