During the discovery phase,
the following information is announced in type-length-values (TLVs) carried within
periodic Information OAMPDUs:
?– OAM configuration Also termed OAM capabilities, advertises OAM capabilities
for the particular link entity, so that the peer station(s) can determine which functions
are supported and accessible, for example, loopback capability, MIB access, and so on.
?– OAM mode This particular field conveys information defining whether the given
link station has active/inactive OAM functionalities. Therefore, such information
is typically used to determine the available functionality of the particular device.
?– OAMPDU configuration This particular field conveys the maximum OAMPDU
size for reception and delivery processes and is typically used to limit OAM traffic
bandwidth allocation, along with frame rate limitation.
?– Platform identity This particular field is a combination of an organization unique
identifier (OUI) and 32-bits of vendor-specific information and is used to identify the
given OAM protocol implementation version. OUI allocation is controlled by the
IEEE, and OUIs are typically equal the first three bytes of a MAC address, the pool
of which is allocated to each Ethernet MAC and equipment manufacturer.
