Wireless Router (All in One) vs Switch

[halomaster]

Yes a SFP would allow you to put whatever type of module you want in, be it fiber or copper. The sg300 ports 9 and 10 are combo, they already have rj45 copper connection so you don't need anything else if you just want to use copper.

SFP stands for (small form-factor pluggable) "transceiver" so not sure where the confusion is?

The old way was GBIC, but you would plug the transceiver into the SFP port

I think I understand now.  I was confused with GBIC.  Under the "Switch Modules" category, they list the GBIC tranceivers.  Under the "Network Tranceivers" category, they list SFP tranceivers.  Neither are inter-changeable.

 

Since SFP+ somewhat supercedes GBIC, do companies still make switches with GBIC?

I guess, I just never saw the use for it on a layer 2 switch.  It isn't like I could vlan the traffic and have it route to another device.  Can't exactly priorize it in that fashion, I guess on the local level you could...but why would you.  Why would you not try to seperate the traffic out?  Why would I have to waste two ports to connect to a single router that is capable of vlans.  I have no use for a layer 2 managed switch in my life.

layer 2 managed would be in the closets. Where you gateway or later 3 routing would happen at the core.

And your qos would be happening at the core level, not at the closets.

My phone's would not exist on the same switch as my computers. Qos would be done by a switch that can police these networks properly. Causing no real need for a managed layer 2 switch.

And how and the hell you going to have more than 1 vlan off a closet without a managed switch? Who said anything about phones? You have users in dept A on the same switch as users in dept B, etc. I would never use anything but a fully managed switch anywhere in a enterprise,

And no you could for many reason want the qos at the closet with contention to the uplink pipe.. Voip phones for sure could be one example, but there could be many other uses as well. And what about all the other features like igmp snooping,

Whre are you connecting your AP to, they would be on a different vlan than the users in the area of the closet. You going to put them on their own switch as well? While sure physical separation is always an option. And yes in a perfect world it is very nice to have all users on one segment in one area of location. But then never heappens, you have printers, you have phones, you have AP, etc. etc. So you need a managed switch at min just for the vlan support. What unmanaged switch allows for lagg, so you can get more than 1 connection to the switch for the uplink. what unmanaged switch is going to do 802.1x or any sort of nac? Or spanning tree or just even basic port security of any kind, etc..

While an unmanaged switch can work in a ma and pa shop.. No freaking way it would ever go into a actual enterprise network.. You have 400 plus users on a floor of a building and your going to plug them in to some unmanaged switches? So you can't even do etherchannel for your uplink? So you have what 48 users with 1 gig up to the core?

And that is why I would have nothing less than layer 3 switches in my closets. Even if they are sg300s. Layer 2 is a waste of time and money. Would rather have a sg300 than a layer 2 2960.

the only thing layer3 buys you is the ability to route, but yes I see your point we have been putting in 3850s in closets.. They are layer 3 yes.. They are not using any layer 3 though, they are not routing.
