Serialized SNMP messages are sent in IEEE 802.3 frames with an Ethernet type field
value of 33100 (hexadecimal 814C16). In IEEE 802 LAN networks using LLC mechanisms
for link layer protocol identification, including IEEE 802.11 wireless LANs, the
SNAP encapsulation method described in subclause 10.5, ???Encapsulation of Ethernet
Frames over LLC,??? of the respective IEEE 802 standard is used. When an SNMP entity
uses this transport mapping, it must be capable of accepting SNMP messages up to 484
octets in size (inclusive). It is recommended that implementations be capable of accepting
messages of up to 1472 octets in size. Implementation of greater values is encouraged
whenever possible.
Main Ethernet OAM Features and Functionalities Operation of the OAM protocol on a
generic Ethernet interface (regardless of whether it is a legacy P2P full-duplex or EFM
Ethernet link) does not affect standard data transmission in any substantial way. The
OAM protocol relies on a ???slow protocol??? with very limited bandwidth consumption,
generating at most 10 frames per second, and by definition, it is not required for normal
link operation, but rather for its maintenance and fault detection.
