Sharing MACs
If the management module is configured to share a RingBuilder MAC,
the management module will continue to use its own Ethernet MAC
until the RingBuilder has completed its initialization.
Once the management module is sharing the MAC, if the RingBuilder
subsequently fails or is removed from the chassis, the management
module will not revert to using its own Ethernet MAC or the MAC on
another RingBuilder Module in a different slot, unless reconfigured
through VT100.
If a working RingBuilder is installed in the same slot as the original
RingBuilder, the management module will start to share the MAC once
the RingBuilder has initialized.
If an MSH chassis containing a management module configured to
share a RingBuilder MAC is powered down, and the Ring Builder has
been removed or is not working when the chassis is powered up again,
the management module will attempt to communicate using its own
Ethernet MAC.
