Stacking and Clustering

Stacking

The Cisco GigaStack GBIC technology offers customers a

range of performance levels, scaling from a 1-Gbps

forwarding rate in a daisy-chain conﬁguration up to a

2-Gbps forwarding rate in a point-to-point connection.

GigaStack Stacking: Independent Stack Bus

With the GigaStack GBIC installed, all Catalyst 3500

series XL and gigabit-enabled Catalyst 2900 series XL

switches can be deployed in a stacking configuration, as

shown in Figure 3. The GigaStack GBIC delivers a 1-Gbps

independent stack bus through standard Gigabit Ethernet

connections, allowing up to nine switches to be stacked and

managed through a single IP address. Support for a

redundant loopback connection is achieved through

secondaryGigaStackGBICsinthetopandbottomswitches,

as shown in Figure 4.
