The show lnm config command displays the logical configuration of this bridge, including the LNM configuration information that needs to be entered at the LNM Station. A sample show lnm config display follows:

To

ring

003, address 0000.3000.5735

In this example, the MAC addresses 0000.3000.abc4 and 000.3000.5735 must be configured as Adapter Addresses at the LNM Station.
