Suggestion for L3 switch

Hello everyone, 

 

I am designing a new office network with Netgear devices. Check the network topology below.

 

 

 

My design will have VLANs. For access layer, I have planned GS724T and GS724TP switches. We have Fortinet firewall with 2 Internet connections. My main concern is the switch which will be the core of the switching network and which will be connected to firewall. I have to do following setup on it: 

 

1. VLAN interfaces

2. VLAN Routing

3. Default route to Firewall (For internet traffic)

4. DHCP Pool for particular VLANs

 

 

So based on these requirements, which Netgear switch should I use here as a core switch? I want 24 GigaEthernet copper port with SFP uplinks. 

 

 

Regards,

Sagar Patel

    So no multigig ethernet is needed?

     

    What speed do you want for the SFP ports?

     

    Any requirement for PoE?

  • Hello,

    1. On the very first post, I have not mentioned "PoE" anywhere, it clearly means that it is not needed..!
    2. In VLAN architecture, I tried to configure default route (which point to Internet gateway device) on GS724 and GS724TP switches, but it gave error.

      Understood.  On the other hand, it doesn't get in the way if you end up with a switch that has it.  I'm not seeing many sellers for the GSM4328S, so IMO you should be open to getting the GSM4328 if price or availability is better.  It has everything you want, plus one feature you don't care about.

      I think that should have worked.  Can you give more details on settings and the error?  If price is a consideration, the GS724 is of course much cheaper than the M4300 series.

       

      FWIW, I agree with schumaku​'s comment on harmonization also.  It will likely work out better if you stick with one series - either the cheaper GS724 models if they meet your needs, or the more capable M4300 models if they don't.
