Model: EAP670  
Hardware Version:
Firmware Version:

Specifying-out a new SMB LAN initially deploying three EAP670s. We expect an average of 15-20 active Wi-Fi connections per AP with bursts up to 50 during office hours. Traffic is a mix of Citrix VPN, VOIP, streaming video, browsers and general office applications (MS Office, Teams). Part of the reason for this build is to utilize VLANs for network segmentation and better security.

 

The topology will look like:

1G fiber from ISP -- Router/Firewall -- Managed Switch #1 -- wired AP (1)

                                                         -- Managed Switch #2 -- wired APs (2)

 

The EAP670s have single 2.5GB ethernet ports and I'm curious if it is worthwhile to have them connected to a switch (TL-SG3210XHP-M2) with 2.5GB ports. The connection from the firewall to the switches will be at 1GB. Would using 2.5GB trunks back to the switches be significantly better than 1GB?

If the 1GB is good enough, I'll probably use two cheaper TL-SG2008Ps - one in the switch room and one on another floor - for simplicity of cabling. If having 2.5GB backhaul would benefit the project I will use one SG3210 and run ethernet cable directly to each EAP670. (I'm listing POE-capable switches because the project may add 2-3 EAP670s via POE over the next six months.)

 

It seems the SG3210 with its 2.5GB ports would have some future-proofing (it also has 2 SFP+ ports for a real backbone someday) or am I being deceived by the gear monkey in me? The $225 difference is within the budget of the project. Ideally, I would use two SG3210s, but the budget doesn't go that high.

 

Thanks for the help,

Greg

Thanks for the guidance. I went with 1GB backhaul for this project as the rack is located in an office environment. The fans were too loud in the SG3210XHP-M2.

Re-configured to the following:

SG3428 - multiple clients

  - SG2210P - 1 EAP670, 2 PoE Ip Cameras

  - SG2008P - 2 EAP670s, 2 PoE Ip Cameras

 

Again, thanks for the help.

As I see, the total bandwidth from ISP is 1G, the client can not get more than 1G speed though you use the 2.5G switch. But if you have a plan to offer a higher speed from ISP, and yes, the 2.5G switch has some future-proofing.

Just striving to develop myself while helping others.

@Virgo 

 

If I have all three APs wired directly to the 2.5GB ports on the switch, does that provide more "breathing room" than if two (or three) APs are sharing a 1GB trunk? Even with 50 typical office clients connected, am I unlikely to saturate a 1GB trunk line so going to 2.5GB is unnecessary?

 

Thanks.

  @GregVLAN I have a single eap670 used in a home environment.

 

Wired to 1gb switch, using ax200 client, best I would see is ~700-800 mbps in iperf3 testing.  Using a 2.5gbps switch I see upwards of 1.6gbps.  This is helpful for large lan transfers.  For internet use, I was seeing about the same ~700 mbps with a gig connection.  With 2.5gbs it saturates my gig fiber easily.

 

To answer your question, it depends on what you're doing. If you want all 3 eap's to be able to work at their peak simultaneous, go with 2.5gbps backhaul.
