Detailed Description

Represents a Spanning Tree Protocol PDU.

Member Typedef Documentation

typedef HWAddress<6> Tins::STP::address_type

The type used to store BPDU identifier addresses.

Constructor & Destructor Documentation

Tins::STP::STP	(	const uint8_t *	buffer,

Constructs a STP object from a buffer.

If there is not enough size for a STP header, a malformed_packet exception is thrown.

Parameters

buffer	The buffer from which this PDU will be constructed.
total_sz	The total size of the buffer.
