Adding a management module in a second slot of the base unit would provide stack, unit, and port-level statistics. Eliminating bottlenecks was the final step of the migration. To accomplish this task, the MetroNet team used Cisco Catalyst 5000 switches across an ATM backbone made up of Cisco LightStream 1010 switches. They created virtual LANs comprising switched 100, switched 10, and shared Fast Ethernet throughout the building. The FastHub repeaters are aggregated by the Catalyst switches, which are in turn connected directly to the UNIX and Novell servers with a combination of ATM and Ethernet adapters.
Users now have Fast Ethernet to the desktop and can access servers via high-speed, switched uplinks.
In June, some of Alberta Energy's remote offices were converted from Token Ring to Fast Ethernet, using technology implemented at headquarters in Calgary. The fact that we can add 200 people very quickly and easily is valuable to us. It's working very well.
