CHAPTER 40 OAM 40.1 OAM Overview Link layer Ethernet OAM (Operations, Administration and Maintenance) as described in IEEE 802.3ah is a link monitoring protocol. It utilizes OAM Protocol Data Units or OAM PDUs to transmit link status information between directly connected Ethernet devices. Both devices must support IEEE 802.3ah. Because link layer Ethernet OAM operates at layer two of the OSI (Open Systems Interconnection Basic Reference) model, neither IP or SNMP are necessary to monitor or troubleshoot network connection problems. The Switch supports the following IEEE 802.3ah features: • Discovery - this identifies the devices on each end of the Ethernet link and their OAM configuration. • Remote Loopback - this can initiate a loopback test between Ethernet devices. 40.1.1 What You Can Do • Use the OAM Status screen (Section 40.2 on page 409) to view the configuration of ports on which Ethernet OAM is enabled. • Use the OAM Configuration screen (Section 40.3 on page 415) to enable Ethernet OAM on the Switch. • Use the OAM Remote Loopback screen (Section 40.4 on page 417) to perform remote-loopback tests. 40.2 OAM Status Use this screen to view the configuration of ports on which Ethernet OAM is enabled. Click Advanced Application > OAM in the navigation panel. XS3800-28 User's Guide 409
