■ Configuring the Switch 8800
■ Setting Terminal Parameters
■ Command Line Interface
Product Overview The 3Com Switch 8800 is a large capacity, modular wire speed Layer 2/Layer 3
switch. It is designed for IP metropolitan area networks (MAN), large-sized
enterprise networks, and campus network users.
The Switch 8800 has an integrated chassis structure. The chassis contains a I/O
module area, fan area, power supply area, and a power distribution area. In the
I/O module area, there are seven, ten, or fourteen slots. Two slots are reserved for
the switch Fabric modules, and the remaining slots are for the I/O modules. You
can install different interface modules for different networks; the slots support a
mixed set of modules.
The Switch 8800 supports the following services:
■ MAN, enterprise/campus networking
■ Multicast service and multicast routing functions and support audio and video
multicast service.
