Introduction
The GigaStack Gigabit Interface Converter (GBIC) is a Cisco proprietary GBIC. The GigaStack GBIC
provides low cost, high bandwidth connections between supported devices. Gigabit connections can be
configured in a point−to−point or cascaded stack configuration, with or without redundancy.
provides low cost, high bandwidth connections between supported devices. Gigabit connections can be
configured in a point−to−point or cascaded stack configuration, with or without redundancy.
The GigaStack GBIC allows you to stack up to nine switches to form an independent backbone that can be
managed with a single IP address. This stack gives the appearance of a single large switch for network
management purposes. You can also form a point−to−point link between two switches. The GigaStack GBIC
supports one full−duplex link (in a point−to−point link), or up to eight half−duplex links (in a stack
configuration) to other Gigabit Ethernet devices.
