dot3OamFunctionsSupported

Module: DOT3-OAM-MIB

OID (symbolic): DOT3-OAM-MIB::dot3OamFunctionsSupported

OID (numeric): 1.3.6.1.2.1.158.1.1.1.6

Node type: OBJECT-TYPE

Type: Bits

Access: read-only

Description: The OAM functions supported on this Ethernet-like interface. OAM consists of separate functional sets beyond the basic discovery process that is always required. These functional groups can be supported independently by any implementation. These values are communicated to the peer via the local configuration field of Information OAMPDUs.

Setting 'unidirectionalSupport(0)' indicates that the OA

entity supports the transmission of OAMPDUs on links that are operating in unidirectional mode (traffic flowing in one direction only). Setting 'loopbackSupport(1)' indicates that the OAM entity can initiate and respond to loopback commands. Setting 'eventSupport(2)' indicates that the OAM entity can send and receive Event Notification OAMPDUs. Setting 'variableSupport(3)' indicates that the OAM entity can send and receive Variable Request and Response OAMPDUs.

What is dot3OamFunctionsSupported?

This read-only bitmask reports which optional Ethernet OAM capabilities the local interface supports: unidirectional transmission, loopback, event notifications, and variable request/response. An admin checks this to know whether, for example, remote loopback testing is even possible on that link before trying to invoke dot3OamLoopbackStatus.
