i960 Core

The i960 core in the FNB module serves two major functions: it provides the

packet forwarding logic and performs all network management services. FNB

modules can be conﬁgured to run as layer 2 bridges, layer 3 routers, or as Fast

Packet Switches. It is possible to run the bridging and routing options

concurrently, but the SFPS option cannot run with bridging and routing.

The i960 core provides the SNMP protocol stacks, as well as support for industry

standard MIBs. Additionally, Cabletron enterprise extension MIBs are supported

for each media type. Advanced management services, such as the Distributed

LAN Monitor, RMON, telnet, and network address to MAC address mapping, are

also provided by the i960 core.
