i960 Core

i960 Core

The i960 core provides the SNMP protocol stacks, to support industry standard 
MIBs. Additionally, Cabletron enterprise extension MIBs are supported for each 
media type. Advanced management services, such as the Distributed LAN 
Monitor, telnet and network address to MAC address mapping, are also provided 
by the i960 core. 

The Host engine sends and receives packets via the CPU’s SmartSwitch ASIC 
Interface. This allows the bridge to perform spanning tree protocol and other 
bridging functions. The SMB Interfaces provide communication to the Host 
Engine for management functions.

INB NIB

Each module that attaches to the Internal Network Bus (INB) has an INB Network 
Interface Block (NIB). The INB NIB converts canonical frames to fixed length data 
blocks for transmission onto the INB. For data blocks received from the INB, the 
INB NIB reassembles the data blocks received from the INB back into canonical 
frames for transmission to the SmartSwitch ASIC then from the SmartSwitch 
ASIC to the front panel ports. 

System Management Buses

There are two management channels within the MMAC-Plus system: the SMB-1 
and the SMB-10. These buses provide side-band management and inter-module 
management communication.

SMB-1 Bus

The SMB-1 is a 1Mbs management bus located within the MMAC-Plus. This bus 
is utilized by all diagnostic controllers in the system including connectivity 
modules, power supply modules and the environmental module. The SMB-1 
transports inter-chassis information between system components, such as power 
and environmental information, as well as diagnostic messages. Periodic 
loop-back test are performed by all modules which share this bus to ensure the 
validity of SMB-1. In the event a failure is detected on SMB-1, the SMB-10 may be 
used as an alternate communication channel.

SMB-10 Bus

The SMB-10 is a 10Mbs management bus located within the MMAC-Plus. This 
bus is used for inter-chassis communication of modules as well as serving as an 
side-band management channel into the MMAC-Plus.
