Configuring OAM Ethernet OAM Figure 1-1 OAM Connection Establishment Switch A Gi1/0/1 (Active mode) Switch B Gi1/0/1 (Passive mode) (1) Infromation OAMPDU from A to B (2) Infromation OAMPDU from B to A As the above figure shows, the OAM entity on Switch A is in active mode, and that on Switch B is in passive mode. Switch A initiates an OAM connection by sending an Information OAMPDU. Switch B compares the OAM information in the received OAMPDU with its own and sends back an Information OAMPDU to Switch A. If the OAM information of the two entities matches, an OAM connection will be established. After that, the two OAM entities will exchange Information OAMPDUs periodically to keep the OAM connection valid. 1.2 Supported Features The switch supports the following OAM features: Link Monitoring, Remote Failure Indication (RFI), and Remote Loopback. Link Monitoring Link Monitoring is for monitoring link performance under various circumstances. When problems are detected on the link, the OAM entity will send its remote peer the Event Notification OAMPDUs to report link events. The link events are described as follows: Table 1-1 OAM Link Events OAM Link Events Definition Symbol Period Error A Symbol Period Error event occurs if the number of symbol errors exceeds the defined threshold within a specific period of time. Frame Error A Frame Error event occurs if the number of frame errors exceeds the defined threshold within a specific period of time. Frame Period Error A Frame Period Error event occurs if the number of frame errors in specific number of received frames exceeds the defined threshold. The period means a specific number of received frames, which can be configured by users. Configuration Guide 356
