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.
