Status
Port |
A unique value for each interface. |
Oper Status |
Indicates the operational status of this Ethernet port. |
Group Admin Status | The administrative status of the group interface.
Up: The interface is enabled and up, and the status of the interface should become standby or operational. Down: The interface is disabled and down, and the status of the interface whould become shutdown. |
OAM Assignment |
Whether this interface has OAM enabled. |
MAC Address |
The MAC address of the peer OAM entity. The MAC address is derived from the most recently received OAMPDU. |
Vendor OUI | The OUI of the OAM peer as reflected in the latest information OAMPDU received with a Local Information TLV. The OUI can be used to identify the vendor of the remote OAM entity. This value is initialized to three octets of zero before any Local Information TLV is received. |
Vendor Information | The Vendor Info of the OAM peer as reflected in the latest information
OAMPDU received with a Local Information TLV.
The semantics of the Vendor Information field is proprietary and specific to the vendor (identified by the PeerVendorOui). This information could, for example, be used to identify a specific product or product family. This value is initialized to zero before any Local Information TLV is received. |
Mode | The mode of the OAM peer as reflected in the latest information
OAMPDU received with a Local Information TLV. The mode of the peer can
be determined from the Configuration field in the Local Information TLV
of the last Information OAMPDU received from the peer. The value is unknown
whenever no Local Information TLV has been received. The values of active(2)
and passive(1) are returned when a Local Information TLV has been received
indicating that the peer is in active or passive mode, respectively.
Values: passive active unknown |
Maximum PDU Size | The maximum size of OAMPDU supported by the peer as reflected in the latest Information OAMPDU received with a Local Information TLV. Ethernet OAM on this interface must not use OAMPDUs that exceed this size. The maximum OAMPDU size can be determined from the PDU Configuration field of the Local Information TLV of the last Information OAMPDU received from the peer. A value of zero is returned if no Local Information TLV has been received. Otherwise, the value of the OAM peer's maximum OAMPDU size is returned in this value. |
Configuration Revision | The configuration revision of the OAM peer as reflected in the latest OAMPDU. This attribute is changed by the peer whenever it has a local configuration change for Ethernet OAM on this interface. The configuration revision can be determined from the Revision field of the Local Information TLV of the most recently received Information OAMPDU with a Local Information TLV. A value of zero is returned if no Local Information TLV has been received. |
Functions Supported | The OAM functions supported on this Ethernet-like interface.
OAM consists of separate functionality sets above the basic discovery
process. This value indicates the capabilities of the peer OAM entity
with respect to these functions. This value is initialized so all bits
are clear. If unidirectionalSupport(0) is set, then the peer OAM entity
supports sending OAM frames on Ethernet interfaces when the receive path
is known to be inoperable. If loopbackSupport(1) is set, then the peer
OAM entity can send and receive OAM loopback commands. If eventSupport(2)
is set, then the peer OAM entity can send and receive event OAMPDUs to
signal various error conditions. If variableSupport(3) is set, then the
peer OAM entity can send and receive variable requests to monitor the
attribute value as described in Clause 57 of [802.3ah].
The capabilities of the OAM peer can be determined from the configuration field of the Local Information TLV of the most recently received Information OAMPDU with a Local Information TLV. All zeros are returned if no Local Information TLV has yet been received. |
