Table 1: show oam ethernet connectivity-fault-management mep-database Output Fields
Field Name | Field Description |
|---|---|
Maintenance domain name | Maintenance domain name. |
Format (Maintenance domain) | Maintenance domain name format configured. |
Level | Maintenance domain level configured. |
Maintenance association name | Maintenance association name. |
Format (Maintenance association) | Maintenance association name format configured. |
Continuity-check status | Continuity-check status. |
Interval | Continuity-check message interval. |
MEP identifier | Maintenance association end point (MEP) identifier. |
Direction | MEP direction configured. |
MAC address | MAC address configured for the MEP. |
Auto-discovery | Whether automatic discovery is enabled or disabled. |
Priority | Priority used for CCMs and linktrace messages transmitted by the MEP. |
Interface name | Interface identifier. |
Interface status | Local interface status. |
Link status | Local link status. |
Remote MEP not receiving CCM | Whether the remote MEP is not receiving CCMs. |
Erroneous CCM received | Whether erroneous CCMs have been received. |
Cross-connect CCM received | Whether cross-connect CCMs have been received. |
RDI sent by some MEP | Whether the remote defect indication (RDI) bit is set in messages that have been received. The absence of the RDI bit in a CCM indicates that the transmitting MEP is receiving CCMs from all configured MEPs. |
CCMs sent | Number of CCMs transmitted. |
CCMs received out of sequence | Number of CCMs received out of sequence. |
LBMs sent | Number of loopback messages (LBMs) sent. |
Valid in-order LBRs received | Number of loopback response messages (LBRs) received that were valid messages and in sequence. |
Valid out-of-order LBRs received | Number of LBRs received that were valid messages and not in sequence. |
LBRs received with corrupted data | Number of LBRs received that were corrupted. |
LBRs sent | Number of LBRs transmitted. |
LTMs sent | Linktrace messages (LTMs) transmitted. |
LTMs received | Linktrace messages received. |
LTRs sent | Linktrace responses (LTRs) transmitted. |
LTRs received | Linktrace responses received. |
Sequence number of next LTM request | Sequence number of the next linktrace message request to be transmitted. |
1DMs sent | If the MEP is an initiator for a one-way ETH-DM session: Number of one-way delay measurement (1DM) PDU frames sent to the peer MEP in this session. For all other cases, this field displays 0. |
Valid 1DMs received | If the MEP is a receiver for a one-way ETH-DM session: Number of valid 1DM frames received. For all other cases, this field displays 0. |
Invalid 1DMs received | If the MEP is a receiver for a one-way ETH-DM session: Number of invalid 1DM frames received. For all other cases, this field displays 0. |
DMMs sent | If the MEP is an initiator for a two-way ETH-DM session: Number of Delay Measurement Message (DMM) PDU frames sent to the peer MEP in this session. For all other cases, this field displays 0. |
DMRs sent | If the MEP is a responder for a ETH-DM session: Number of Delay Measurement Reply (DMR) frames sent. For all other cases, this field displays 0. |
Valid DMRs received | If the MEP is an initiator for a two-way ETH-DM session: Number of valid DMRs received. For all other cases, this field displays 0. |
Invalid DMRs received | If the MEP is an initiator for a two-way ETH-DM session: Number of invalid DMRs received. For all other cases, this field displays 0. |
Remote MEP identifier | MEP identifier of the remote MEP. |
State (remote MEP) | State of the remote MEP: idle, start, ok, or failed. |
MAC address | MAC address of the remote MEP. |
Type | Whether the remote MEP MAC address was learned using automatic discovery or configured. |
Interface | Interface of the remote MEP. A seven-digit number is appended if CFM is configured to run on a routing instance of type VPLS. |
Last flapped | Date, time, and how long ago the remote MEP interface went from down to up. The format is Last flapped: year-month-day hours:minutes:seconds timezone (hours:minutes:seconds ago). For example, Last flapped: 2002-04-26 10:52:40 PDT (04:33:20 ago). |
Remote defect indication | Whether the remote defect indication (RDI) bit is set in messages that have been received or transmitted. |
Port status TLV |
|
Interface status TLV |
|
Action profile | Name of the action profile occurrence associated with a remote MEP. |
Last event | When an action profile occurs, displays the last event that triggered it. |
Last event cleared | When all the configured and occurred events (under action profile) are cleared, then the action taken gets reverted (such as down interface is made up) and the corresponding time is noted and displayed. |
Action | Action taken and the corresponding time of the action occurrence. |
