Detailed Description

Token that represents fields of DHCPv6 packet.

For example in the expression pkt6.msgtype == 1 this token represents the message type of the DHCPv6 packet. The integer values are placed on the value stack as 4 byte strings.

  • msgtype
  • transid

◆ evaluate()

void TokenPkt6::evaluate ( Pkt & pkt,
ValueStack & values )

Gets a value of the specified packet.

The evaluation uses fields that are available in the packet. It does not require any values to be present on the stack.

EvalTypeErrorwhen called for a DHCPv4 packet
pkt- packet from which to extract the fields
values- stack of values, 1 result will be pushed

Implements isc::dhcp::Token.
