to an end-node, the media converter shuts down the connection to the
other port, thus notifying the end-node that the connection has been
lost.
OAM BYPASS Mode
In this mode, the line card receives OAMPDU packets, but forwards
them onto the other port. This allows Converteon to be used in a
network where the Converteon chassis is not part of the IEEE802.3ah
end points. (i.e. in this mode, the OAM function of the media blade is
disabled). To configure as OAM bypass mode, the module will pass all
OAMPDUs whose vendor OUI is not Allied Telesyn.
OAM Visible Mode
In this mode, the line card does respond to OAMPDU packets. In an
unmanaged chassis, the line card will be in passive mode. In a
managed chassis, the line card can either be in passive or active mode
depending on how it is software configured. For detailed information,
refer to Table 3, “OAM Active and Passive Mode Behaviors” on page
89. To configure as OAM visible mode, the module will respond to all
OAMPDUs.
Link Test Mode
This is the default setting. The mode is to test the connections between
the line card ports and the end-nodes that are connected to the ports. If
a network problem occurs, you can perform a link test to determine
which port is experiencing a problem, and so be able to focus your
troubleshooting efforts on the cable and end-node where the problem
resides.
