Please recommend a Cisco Switch (All ports of Gigabit Capacity)

Hi All !

I am looking for a backbone switch with all ports of gigabit capacity. I also got some suggestions from my question id:

Most of the recommendations were for Cisco 3750 Series. My management is asking me the exact model to buy and for the specifications, cost etc.

I can see that there are models in Cisco 3750 Series. Please explain me the terms so that I can take a good decision on myself :

1. What are SFP Ports ?
2. What is meant when you say 100 Mbps ports with "Power Over Ethernet" ?
3. 100BASE-FX, in this does "FX" mean Fiber Optics ? Then can it also be used for Copper or NOT ?
4, What are meanings of "TS, PS, FS, T, S and WS)

I want your recommendations because it is a one time investment and that is too high. Once we purchase a switch and then we find that we could have gone for better switch with a little price difference, then supplier will not replace it.

SFP are modules that plug in the 3750 switch. They can be UTP or Fiber
It means that if you have IP telephony or wireless access point they can be powered from switch
FX means Fiber

3750 is a really great switch


In this link there are all the models of the 3750. There is also a chat tool with a cisco representative that can help you with everything!!!!!

Thanks for the comment.

Please hava a look at (http://www.cisco.com/en/US/products/ps6069/index.html). It has these specifications:

Cisco Catalyst 3750G-24PS-E (WS-C3750G-24PS-E)

(A) 24 Ethernet 10/100/1000 ports with Power over Ethernet and 4 small form-factor pluggable (SFP) transceiver-based Gigabit Ethernet ports
(B) 32-Gbps, high-speed stacking bus
(C) Innovative stacking technology
(D) 1 rack unit (RU) stackable, multilayer switch
(E) Enterprise-class intelligent services delivered to the network edge
(F) Enhanced Multilayer Image Software (EMI) installed
(G) Full dynamic IP routing

Query: 1.
It features: (G) Full dynamic IP routing

Does it mean that if I make VLANs in this switch, I will NOT need any Router with VLAN feature (like older Router 2600 Series) for VLAN Routing. Will the switch itself perform Routing between VLANs configured in it. If so, then it is fantastic. Please clerify my doubt.

Query 2.
So what should I get from the first specification (See (A)" ? You say that SFP are PoE but it is confusing me that why here it is "24 Ethernet 10/100/1000 ports with Power over Ethernet" ?

Query 1:

These switches are L3 switches and that means that they capable of performing intervlan routing and normal routing. Think of them like a router with 24 or 48 ethernet interdaces.

Query 2:

SFP is not POE

SFP are typically 2 or 4 extra ports that you have to buy modules to plug in in order to use them. Those modules can be either Fiber or UTP
POE is power over ethernet and if the switch supports the feature then you can plug in the ports IP phones or access points without using external Power!!

Thanks for the instant reply.

One last question:

For Query 1:
Two years back, I had made VLANs in a Cisco 2950 Switch and for Inter-VLAN Routing, I used Cisco 2620 Switch. You mean that now there is NO need for this extra router. Well...it is good and I really didn't know it.

So, do we need to do some Routing Configuration in these L3 Cisco Switches (like Cisco 2600 Series Routers) or just making VLANs will, by default, allow Routing in between these VLANs ?

Thanks again.
2950 are Layer 2 switches. So you need a router for intervlan routing. But 3750 are Layer 3 and the router is not need to route between vlans

for intervlan routing in the 3750 you need to enable routing
switch(config)# ip routing

then for each vlan create a vlan intergace and assign IP addresses to it

after that you are done!!!
