Chapter 1 Overview

Network Configuration Examples

–

1000BASE-ZX GBIC: fiber connections of up to 328,084 ft (100 km)

–

1000BASE-T GBIC: copper connections of up to 328 ft (100 m)

–

Catalyst 2900 XL 1000BASE-T: copper connections of up to 328 ft (100 m)

• Redundant Gigabit backbone—Using HSRP, you can create backup paths between

Catalyst 4908G-L3 switches. To enhance network reliability and load balancing for different

VLANs and subnets, you can connect the Catalyst 2900 XL and Catalyst 3500 XL switches, again

in a star configuration, to two backbone switches. If one of the backbone switches fails, the second

backbone switch preserves connectivity between the switches and network resources.
