FNB Interface

FNB Interface

MMAC-Plus modules are designed with one of two attachment policies. One allows dual attachment of a module to either FNB-1 or FNB-2; the second allows dual attachment to both FNB-1 and FNB-2. The 9F106-01 has one dual attachment to the FNB backplane, connecting to either FNB-1 or FNB-2. The module can insert into the FNB or bypass it. These ﬂexible conﬁguration options make the MMAC-Plus ideal for networks designed to Bridge/Route multiple lower speed LANs to FDDI and/or networks designed using an FDDI collapsed backbone.

CPU

The CPU provides all forwarding/ﬁltering decisions, the SNMP protocol stacks, as well as support for industry standard MIBs.
