Constructor Details

InterfacePdu

public InterfacePdu(SnmpContextBasisFace con,
 Observer o,
 int interf)
             throws PduException,
IOException

Constructor that will send the request immediately.

Parameters:

con - the SnmpContextBasisFace

o - the Observer that will be notified when the answer is received

interf - the index of the requested interface

Throws:

PduException

IOException

Method Details

getIndex

public int getIndex()

Returns the index of the interface.

Returns:

the index

getSysUpTime

public long getSysUpTime()

Returns the time (in hundredths of a second) since the network management portion of the system was last re-initialized.

getDescription

public String getDescription()

Returns the description of the interface.

Returns:

the description

getOperStatus

public int getOperStatus()

Returns the operational state of the interface.

Returns:

the operational state

getOperStatusString

public String getOperStatusString()

Returns the string representation of the operational state of the interface.

Returns:

the operational state as string

See Also:

• getOperStatus()
• getOperStatusString(int)

getOperStatusString

public String getOperStatusString(int status)

Returns the string representation of a operational state.

See Also:

• getOperStatusString()

getInOctet

public long getInOctet()

Returns the total number of octets received on the interface, including framing characters.

getOutOctet

public long getOutOctet()

Returns the total number of octets transmitted outOctets of the interface, including framing characters.

getSpeed

public long getSpeed(InterfacePdu old)

Calculates the speed of the interface. This is done by providing the method with the previous value of this interface. An interface is marked by its index.

Parameters:

old - The previous value of this interface

getNumIfs

public static int getNumIfs(SnmpContextBasisFace con)
                     throws PduException,
IOException

Returns how many interfaces are present.

Returns:

the number of interfaces

Throws:

PduException

IOException
