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.
