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
92. 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.
Changing Line
