What’s New at
Revision 8.2.0?
This section describes the new features, software enhancements, and
corrections implemented at this release.
New Features The following features have been added at this release.
Support for the Fast Ethernet Switching Module (FESM)
The Fast Ethernet Switching Module (FESM) provides high-function
switching of traffic among Fast Ethernet workstations and subnetworks
over the multigigabit high-speed interconnect (HSI) bus of the
CoreBuilder
6000 system.
The FESM module is available in two configurations:
■ Eight 100BASE-TX ports using RJ-45 connectors
These ports support connections to unshielded twisted pair (UTP) Category
5 media.
■ Six 100BASE-FX ports using SC connectors
These ports support connections to multimode fiber media.
The FESM automatically learns the MAC-layer addresses of
workstations on attached subnetworks and forwards packets to their
appropriate destinations.
When used with CoreBuilder
Extended
Switching software, the FESM also supports routing between attached
subnetworks. In addition, the FESM fully complies with the IEEE
802.1d bridging standard.
The FESM requires CoreBuilder 6000 software revision 8.2.0 or greater. This
software, in turn, requires that one of the following LMM+ versions be
installed in system slot 1:
■ Revision 1.21 or greater of the revision 1 LMM+
■ Revision 2.12 or greater of the revision 2 LMM+
CAUTION: If you attempt to run CoreBuilder system software 8.2.0 on an
earlier revision of the LMM+, the system fails to reboot automatically when
you turn it on.
