Class IfTable

  • All Implemented Interfaces:
    Collectable, ProxiableTracker

    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.
