Network switch infra design
Posted on 2013-11-06
This is a design for new network using 7 switches - 5 x Cisco 2960 (with 4 SFPs), and 2 x HP Procurve V1910-24 switches, plus 2 12-port 100-based switches. All are gigabit switches. The areas and number of network points needed include, basement (12), 1st floor (7), 2nd floor (28), 3rd floor (18), and 4th floor (55).
Network cables of Cat6 are planned to running through the above areas. 2nd and 3rd floors are admin & business departments, in which high-ranking management personels positioned. 4th floor is computer lab, and a Internet line/router/firewall, are located. One of the major objective is, all users of any floor must able to access to Internet without problem.
Distances between 4th floor to basement is about 220 m, to 1st floor is about 120 m, to 2nd floor is 30 m, and to 3rd floor is 15 m. I'm thinking to set up 2 2-layer switch infra, with 1 core/distribution switch located at 4th floor, and the rest of the 6 switches as access-layer switches.
For 4th floor, 1 Cisco 2960 switch as core, plus 2 HP v1910 24-port switches uplinked with cat6 cable to the core switch; for 3rd floor, 1 Cisco 2960 switch as access-layer, and uplinked with cat6 cable to core switch; for 2nd floor, 1 Cisco 2960 switch as access-layer, and uplinked with cat6 cable to core switch, plus a 12-port 100-based switch cat6 cable uplinked to core switch; for 1st floor, 1 Cisco 2960 switch fibre-optic uplinked to core switch; for basement, 1 cisco 2960 switch fibre-optic uplinked to core switch.
The fibre-optic is multi-mode, so it should support up to 400 m? Any problem with the design? Can it be better? Does any VLAN and trunking are needed?
