Note: DECnet Phase IV routing is not supported on token-ring ports.
The Multiprotocol Interconnect module uses a 32-bit RISC processor (80960FA)
for high performance, allowing you to forward up to 45,000 packets per second
when bridging and up to 30,000 packets per second when routing IP. The
performance of the module will vary depending on the number of routing
protocols running in the module as well the size of the packets.
This module can be managed using a local ASCII terminal (VT100/VT220)
connected to the module through an RS-232 port (locally or via a dialup modem
operating at speeds up to 9600 bps). It can also be managed remotely using
Telnet.
The Multiprotocol Interconnect module, also supports SNMP allowing it to be
managed using an SNMP manager.
New software can be downloaded to the Multiprotocol Interconnect module using
BOOTP, TFTP, or X-Modem. This can be done:
1. Out-of-band - Using a local or mode m attached PC to the RS-232 port on the
2. Inband - Using an IP network
The management facilities of the Interconnect module allow you to:
The Multiprotocol Interconnect module consists of:
1. Backplane Interface Module (BIM):
2. Router Engine Module (REM):
3. I/O cards (available on the two-slot module):
240
8260 Multiprotocol Intelligent Switching Hub
module.
Configure the module for bridging and/or routing functions
Monitor traffic counters
Monitor diagnostics information
Monitor address table information for routing and bridging functions
This module provides the following functions:
Connection to the ShuntBus and Enhanced TriChannel Ethernet/802.3
segments
A DB-9 connector for local management
Housing for two additional I/O cards (2-slot module only)
This module is installed on the BIM and provides housing for an i960
processor.
Up to two I/O cards (in any combination) can be installed on the BIM to
provide connections for up to two external token-ring and/or Ethernet
segments.
Note
The connectors on the token-ring I/O modules are via DB-9 connectors.
