Which Cisco Switch is right for us,

It's time to replace our ageing Cisco switches as we are moving to a gigabit phone system. We have been quoted for Cisco 3580 - POE 5k for a 24 port and nearly 10k for 48 port - my boss fell off his chair.

This is our network 50 users split over three office's Site 1 has break out to internet, Site 2 & 3 link via 20mb lines.

We need to split the VoIP traffic via a vlan but that is pretty simple setup I would say.

My question is do we need to 15K on Cisco switches? Can we come down the Cisco product ladder a bit? We are being advise to use tier one ie Cisco or HP - but haven't been told why? The new phone system I tested over a cheap Gigabyte NetGear and it works fine.

I need to justified to my boss why we should spend 15k - any advise would be great.

Current config is from a Cisco 2950 which isn't POE but stills works.

Any advise or suggestion would be great.

Thanks
Ian.

I don't know that's the point of asking on here.

Do Cisco make a 2950 POE? and what is a Meraki is that a brand of switch?

Thanks
Ian.

POE injectors are easy enough to source for around $10 ea. 50 would be $500. That would let you power each phone from a wall socket, while retaining the existing non POE switches. Bit messy, but it is a option that should work.

My question is do we need to 15K on Cisco switches?
Most likely not.
What about the 2960 POE?
2960X series is more than good enough for VoIP. But you should implement end-to-end QoS for VoIP (so L3 device should be also be configured for QoS)

Agree with Predrag.  2960X would be more than enough for what you need.  3850 is extreme overkill.

"So L3 device should be also be configured for QoS" -

I am correct in saying that Qos would be setup on the router which is level 3 - we use Cisco 2800 and although I don't have access to the configuration I am pretty sure that's how it's configured.

Would that make sense?

Thank Ian

It is better to check configuration than guess. :) QoS should be configured on L2 (2950, 2960... ) and on L3 devices (2800...).

..and yes you can get PoE 2960-X models (check the wattage for the amount of devices you want to deploy)
