This section describes the new features, software enhancements, and 
corrections that are implemented at this release.

The following features have been added at this release.

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.
