public DhcpdConfiguration()
```
- Method Detail
  - hasPort
```
public boolean hasPort()
```
    Method hasPort.
    
    Returns:
    
    true if at least one Port has been added
  - getPort
```
public Integer getPort()
```
    Returns the value of field 'port'. The field 'port' has the following description: TCP port number used for internal communication within OpenNMS between the DHCP poller and other OpenNMS daemons. The port is set to 5818 in the default configuration file.
    
    Returns:
    
    the value of field 'Port'.
  - setPort
```
public void setPort(Integer port)
```
    Sets the value of field 'port'. The field 'port' has the following description: TCP port number used for internal communication within OpenNMS between the DHCP poller and other OpenNMS daemons. The port is set to 5818 in the default configuration file.
    
    Parameters:
    
    port - the value of field 'port'.
  - deletePort
```
public void deletePort()
```
  - getMacAddress
```
public String getMacAddress()
```
    Returns the value of field 'macAddress'. The field 'macAddress' has the following description: Ethernet MAC address used as the client MAC address in DHCP DISCOVER packets sent by OpenNMS. The MAC address is set to 00:06:0D:BE:9C:B2 in the default configuration file.
    
    Returns:
    
    the value of field 'MacAddress'.
  - setMacAddress
```
public void setMacAddress(String macAddress)
```
    Sets the value of field 'macAddress'. The field 'macAddress' has the following description: Ethernet MAC address used as the client MAC address in DHCP DISCOVER packets sent by OpenNMS. The MAC address is set to 00:06:0D:BE:9C:B2 in the default configuration file.
    
    Parameters:
    
    macAddress - the value of field 'macAddress'.
  - getMyIpAddress
```
public String getMyIpAddress()
```
    Returns the value of field 'myIpAddress'. The field 'myIpAddress' has the following description: IP address used as the relay IP address in DHCP DISCOVER packets sent by OpenNMS. Setting this attribute to "broadcast" places the DHCP poller Setting this attribute places the DHCP poller in "relay" mode instead of the default "broadcast" mode. In "relay" mode, the DHCP server being polled will unicast its responses directly back to the specified ip address rather than broadcasting its responses. This allows DHCP servers to be polled even though they are not on the same subnet as the OpenNMS server, and without the aid of an external relay. This is usually set to the IP address of the OpenNMS server.
    
    Returns:
    
    the value of field 'MyIpAddress'.
  - setMyIpAddress
```
public void setMyIpAddress(String myIpAddress)
```
    Sets the value of field 'myIpAddress'. The field 'myIpAddress' has the following description: IP address used as the relay IP address in DHCP DISCOVER packets sent by OpenNMS. Setting this attribute to "broadcast" places the DHCP poller Setting this attribute places the DHCP poller in "relay" mode instead of the default "broadcast" mode. In "relay" mode, the DHCP server being polled will unicast its responses directly back to the specified ip address rather than broadcasting its responses. This allows DHCP servers to be polled even though they are not on the same subnet as the OpenNMS server, and without the aid of an external relay. This is usually set to the IP address of the OpenNMS server.
    
    Parameters:
    
    myIpAddress - the value of field 'myIpAddress'.
  - getExtendedMode
```
public String getExtendedMode()
```
    Returns the value of field 'extendedMode'. The field 'extendedMode' has the following description: Set extended DHCP polling mode. When extendedMode is false (the default), the DHCP poller will send a DISCOVER and expect an OFFER in return. When extendedMode is true, the DHCP poller will first send a DISCOVER. If no valid response is received it will send an INFORM. If no valid response is received it will then send a REQUEST. OFFER, ACK, and NAK are all considered valid responses in extendedMode. Caution on usage: If in extended mode, the time required to complete the poll for an unresponsive node is increased by a factor of 3. Thus it is a good idea to limit the number of retries to a small number.
    
    Returns:
    
    the value of field 'ExtendedMode'.
  - setExtendedMode
```
public void setExtendedMode(String extendedMode)
```
    Sets the value of field 'extendedMode'. The field 'extendedMode' has the following description: Set extended DHCP polling mode. When extendedMode is false (the default), the DHCP poller will send a DISCOVER and expect an OFFER in return. When extendedMode is true, the DHCP poller will first send a DISCOVER. If no valid response is received it will send an INFORM. If no valid response is received it will then send a REQUEST. OFFER, ACK, and NAK are all considered valid responses in extendedMode.

Thus it is a good idea to limit the number of retries to a small number.
    
    Parameters:
    
    extendedMode - the value of field 'extendedMode'.
  - getRequestIpAddress
```
public String getRequestIpAddress()
```
    Returns the value of field 'requestIpAddress'. The field 'requestIpAddress' has the following description: Set the IP address to be requested in DHCP REQUEST queries. This attribute is only used when the extendedMode attribute is set to "true". If an IP address is specified, it will be requested in the query. If the string "targetHost" is specified, the DHCP server's own ip address will be requested. Since a well-managed server will probably not respond to a request for its own IP address, this parameter can also be set to the string "targetSubnet". This is similar to "targetHost", except the last octet of the DHCP server's IP address is incremented or decremented by 1 to obtain an IP address that is on the same subnet. The resulting address will not be on the same subnet if the DHCP server's subnet length is 31 or 32. Otherwise, the algorithm used should be reliable.
    
    Returns:
    
    the value of field 'RequestIpAddress'.
  - setRequestIpAddress
```
public void setRequestIpAddress(String requestIpAddress)
```

    Parameters:
    
    requestIpAddress - the value of field 'requestIpAddress'
  - equals
```
public boolean equals(Object obj)
```
    Overrides the java.lang.Object.equals method.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj -
    
    Returns:
