IEEE 1588v2 PTP
Note that a TTL value of zero can be used, for example, to signal that the sending port has initiated
a port shutdown procedure.
The end of a LLDPDU TLV marks the end of the LLDPDU.
The IEEE 802.1ab standard defines a protocol that:
•
•
•
•
•
Network operators must be able to discover the topology information in order to detect and
address network problems and inconsistencies in the configuration. Moreover, standard-based
Page 296
Advertises connectivity and management information about the local station to adjacent
stations on the same IEEE 802 LAN.
Receives network management information from adjacent stations on the same IEEE 802
LAN.
Operates with all IEEE 802 access protocols and network media.
Establishes a network management information schema and object definitions that are
suitable for storing connection information about adjacent stations.
Provides compatibility with a number of MIBs as depicted in
