Distribution Layer Switches (DLs) extend the core campus network into a building. Network connections generally include one DL connected at 1 Gigabit per second (Gbps). Each building is connected to two of the university’s core network locations for redundancy.
Campus Distribution Layer Switch Upgrades
In 2007 the university agreed that DLs are integral to reliable core network service and the routine and systematic upgrade of these switches should be scheduled and funded centrally. The Provost approved a new Core Network funding model which included the funding for one DL per building or complex of buildings and uninterruptable power supplies needed by ITS.
Funding for secondary switches, additional ports, or non-standard configurations for primary or secondary switches are the responsibility of the unit. Secondary switches will be capital financed by ITS and the unit has a monthly recurring charge over four years to recover equipment and financing costs.
See Distribution Layer (DL) Upgrade Project- Building Status for information
For units wishing to install a second DL or apply non-standard configurations can:
- Refer to the Core Network Circuit Rates for general pricing
- Contact their ITS Infrastructure Project Manager for a more specific pricing
Administration, maintenance, and support of DLs are handled by UMnet Administration.
