When applied to Ethernet – OAM is typically assumed to refer to the layer 2
(MAC layer), management protocols, specifically 802.3ah and 802.1ag. Layer
2 management protocols do not need higher level transport protocols to
operate, OAM data is transferred in standard multicast Ethernet frames.
802.3ah OAM:
(LINK-OAM)
Is a point-to-point protocol designed to verify a specific
link between two directly connected devices (over
copper or fiber), which support 802.3ah OAM. One
device must be configured to be an active OAM device,
the other a passive (typically the core switch would be
the active device, the end device passive). 802.3ah
OAM provides link status, remote fault detection and the
ability to initiate a loopback circuit.
802.1ag:
(SERVICE-OAM)
Often referred to as Connectivity Fault Management
(CFM), is an end-to-end protocol designed to verify a
specific network path between two devices that may well
be in different geographical locations. CFM allows the
network operator to administer, monitor and debug the
network using continuity check (a heart beat message),
link trace (similar to traceroot, but operating at the MAC
layer) and finally loopback (can be likened to a layer 2
ping).
3.2 iView² Management Software
iView² is the Black Box management software that features a Graphical User
Interface (GUI) and gives network managers the ability to monitor and control
the manageable Black Box products.
iView² is available in several versions, including a WebServer version 3.0, and
can also function as a snap-in module for HP OpenView Network Node
Manager and other third party SNMP Management software.
iView
2
supports the following platforms:
• Windows 2000
• Windows XP
• Windows Vista
• Windows 7
Please see the SNMP Management Module manual for software configuration
options.
