byteblowerll.byteblower.DHCPv4Protocol

class byteblowerll.byteblower.DHCPv4Protocol(*args, **kwargs)

The DHCPv4Protocol is the entry point to configure the DHCP client behavior of a ByteBlowerPort.

A ByteBlowerPort can perform DHCP the get an IP address, gateway and netmask. Currently, no other options are supported but this will change in the future.

Users can configure the timing parameters used in the different stages of the DHCP protocol: - Discover

During the discover stage the ByteBlower port will broadcast discover messages.

• Request

  Once one or more offers are received the ByteBlower port will broadcast its request message. If acknowledge the ByteBlower port will start using this address.

• Renew

  When half of the lease time received in the acknowledge message of the request has passed, a ByteBlowerPort will sent a renew message to the server to extend its lease.

Although DHCP allows clients to use unicast messages in the Request stage, ByteBlower currently only supports broadcast messages in this stage.

A DHCPv4Protocol object also supports different retransmission strategies:

Fixed

This policy will use the same timeout value for each timeout.

RFCSuggested

This policy implements the policy described in :rfc:2131.

__init__(*args, **kwargs)

Initialize self. See help(type(self)) for accurate signature.
