14 COREBUILDER 6000 EXTENDED SWITCHING SOFTWARE REVISION 8.2.3
What’s New at
Revision 8.2.0?
This section describes the new features, software enhancements, and
corrections that are implemented at this release.
New Features The following features have been added at this release.
Fast Ethernet Switching Module (FESM) Support
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 has two configurations:
■ Eight 100BASE-TX ports that use RJ-45 connectors
These ports support connections to unshielded twisted pair (UTP) Category
5 media.
■ Six 100BASE-FX ports that use 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 you install one of the following LANswitching
Management Module Plus (LMM+) versions 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 or greater
on an earlier revision of the LMM+, the system fails to reboot when you turn
it on.
