I got opportunity to setup network for 120 users in a office. They gave me 5 manageable switches with each 48 ports. 2 switches are Dlink and 3 are Dell powerconnect 5548. I connected all switches and made star topology as attached image along this question.
From these 120 users only 15 users would use downloading and video streaming rarely not daily. others would only use web browsing and email checking.
My questions as follow :-
1) I have connected all switches with Ethernet ports even stacking facility is available. Is right to connect two switches with ethernet port?
2) Will ethernet port bear all traffic or do I require stacking ?
3) Which router I should use at gateway. I need router which support URL filtering and VPN feature. I heard cisco routers have this features.
4) As in figure, Two Dell switches in middle configured by me, When I connect any laptop/desktop to these two switches then arp response from router come late takes 10-15 seconds. But on others switches arp response comes quickly as they pre-configured already by someone else.
What I configured on these two dell switches as follow ?
a) Just assigned ip address and gateway to it.
b) just enabled spanning tree button from web interface
thats it, Do I need to configure something else also ?
Looking for help.
