Ah Oam; 3-20.1 Port Config - ZyXEL Communications XGS3600 Series Manual

3-20 802.3ah OAM

For Carrier Ethernet application that customer need to reduce operating cost and increase the
remote maintain availability. The advent of Ethernet as a metropolitan and wide-area
networking technology has accelerated the need for a new set of OAM protocols. Service
provider networks are large and complex with a wide user base, and they often involve
different operators that must work together to provide end-to-end services to enterprise
customers. While enterprise end-customer demands continue to increase, so do the
requirements for service provider Ethernet networks, particularly in the areas of availability
and mean time to repair (MTTR). Ethernet OAM addresses these challenges and more,
thereby directly impacting the competitiveness of the service provider. Ethernet has been
used as a LAN technology for many years, and enterprises have managed these networks
effectively, Ethernet OAM is a broad topic, but this paper will focus on three main areas of
Ethernet OAM that are most in need by service providers and are rapidly evolving in the
standards bodies: Service Layer OAM (IEEE 802.1ag Connectivity Fault Management), Link
Layer OAM (IEEE 802.3ah OAM), and Ethernet Local Management Interface (MEF-16 E-LMI).
Each of these different OAM protocols has unique objectives and is complementary to the
others. IEEE 802.1ag Connectivity Fault Management provides "service" management.

3-20.1 Port Config

This chapter allows the user to inspect the current Link OAM port configurations, and change
them as well. It will help user to understand the Port configuration parameter what you need
to set when you enable IEEE802.3ah OAM function on the switch.
Web Interface
To configure the 802.3ah OAM in the web interface:
1. Click Configuration, 802.3ah OAM then Port config.
2. Evoke which Port wants to enable OAM function.
3. Scroll to select OAM mode with Passive or Active.
4. Evoke which port wants to support Loopback, Link monitor, MIB Retrieval or Loopback
operation.
4. Click the Apply to save the setting
5. If you want to cancel the setting then you need to click the Reset button.
It will revert to previously saved values
.
