10GB Lan causing strange performance issues, goes away when switched over to 1GB
-

I've read through the article, albeit quickly, I did not see any reference to "CTF" mode, quick google search comes back with nothing.
From what I have read the 3548-X has increased shared buffer pools and better hardware / architecture that results in super low latencies. I am not trading stocks but I am competing in E-Sports hence the quest for the lowest latency home network is my end game here, which is what led me to find the Nexus 3548-X.
What doesn't make sense to me is how cheap these switches can be bought for on Ebay. You can get a 48-Port 10GB 3548-X switch for $200, is there something I am seriously missing. I would wipe the switch, setup my trunk port and several Vlans and call it a day, my switch config is not overly complicated. The IP Base lic is also fine for me being I route my Vlan traffic on the pfSense side, so Layer 2 is all I need.
-
In addition, when it comes to "Normal" vs "Warp" mode, I think I would prefer to run in "Warp" mode, I do not see any down side to that setup for my use case. At any point in time I will only have 4-12 hardwired clients active, only 2-3 of which will have any kind of substantial traffic.

Probably because of how loud and power hungry they are. Like most (all?) older 10G switches.

@lnguyen Switches are either store & forward or cut through forwarding. Its $200 because its an EOL DC switch. I deployed hundreds of these. It runs NexusOS but the command structure is very similar to that of Cisco Catalyst switches. Noise level and power draw will be higher than your current one. Its also all SFP+ ports.

According to the data sheets the 3650 uses 99W at idle and the 3854-X uses 112W at idle. In the read world my 3650 with light load is consuming 60W according to my UPS. Both have a similar PSU and FAN design I cant imagine the power or sound being any different.
That said, do you have any other recommendations, perhaps a Cisco 350X or 550X would be better suited for my needs. I would prefer to drop the my current 60W load to 20W if possible, but again I am chasing speed here.
-
I have nothing in mind. I couldn't run a switch like that here.
-
What are your thoughts on the Cisco 350X or 550X ?
-
@ngr2001 It’s Cisco’s lowest end gear. Don’t care for that product line in that channel of the market. There are other brands serving that channel that have better products
-
@lnguyen I am open to any suggestions, I would love some suggestions on makes and models that I can research and price check on ebay.
-
@ngr2001 What are you trying to achieve? Seems as though your issue was resolved with the command I gave you. Are you trying to get lower latency? The lower latency of CTF of a Nexus switch doesn't really improve anything for you when the Internet latency is far greater.
-
My goals in order of importance:
- 10Gb ports (I only have 2 today, that's not enough need 12-24)
- Lower Latency (May be moot to your point)
- Lower Power consumption (Current 3650 is using 60W)
- Reduce noise (Currently not an issue with the 3650)
- Price needs to be under $500 bucks new or used
So in short I am looking for either a 24 or 48 port switch wherein all ports are 10Gb, preferably RJ45 but SPF+ is fine too.
That is why the nexus 3000 was so appealing to me, the only ? would be is if the nexus would be louder and use more energy than the 3650.

@lnguyen Go look for Cisco Catalyst WS-C3850-12X-48U for well under $500. Or Cisco Catalyst WS-C3850-24XU. The difference is 48 ports of which ports 37-48 are 5-speed mGig vs 24 ports that are 5-speed mGig.

I'll def take a look thank you, however I just stumbled onto this gem.

This has me seriously considering a Brocade ICX7250. It has 8(x) 10Gb ports and 48 1Gb ports. You can get these on ebay for under 100 bucks and the idle power is around 50W and from what I read its near silent. It also keeps getting better in that anyone can download their latest firmware and the license is basically free (honor system).
It seems to check off all my boxes, I have no experience with Brocade and from what I read they seem to pretty reliable and fast, thoughts ??
-
@ngr2001 Whatever works for you. Brocade/Ruckus ICX7250 are enterprise switches. Whatever you buy is going to be overkill for what you are probably doing. What drives your 10GbE needs?
-
I have a Brocade ICX6450 (4 10G ports) and have been pretty happy with it. I did swap out the fans for some quieter ones.
I was also looking at the 7250. Missed one a few weeks back on ebay. Most are 48 port and I just don't need that.
And, yes, total overkill for my needs!
-
Good to hear, they seem like a really solid choice, plenty of ebay for cheap, any idea what your real world idle power draw is ?
-
The 10Gb need comes from running a file server / NAS at 10Gg, a few of my workstations support 10Gb and I want to move large 4K video files faster. Makes a huge difference when dealing with dozens of 8GB+ files. I will also be upgrading to Wifi 7 and the AP's support 10GB. I wired my house back in the day with Cat 6E 550mhz premium cable so I should be good to go, just need the switch at this point.

I don't see why you would want the Brocade over the Cisco then? The copper ports with PoE are 1GbE. The WS-C3850-12X-48 or WS-C3850-24X have 12 or 24 x mGig ports with PoE+ to support this future WiFi 7 AP. Adding the Network module C3850-NM-8-10G will give you 8 x 10GbE SFP+ ports

The ICX7250 has 8(x) 10Gb SPF+ ports, all 8 are full 10Gb, 2 only come active by default, you can activate the other 6 with a single "free" license command. The other 45 RJ45 ports are 1Gb. In addition the rated idle power consumption is only 50W and I am sure that will likely benchmark lower especially as I disable ports etc. Seems like a win win to me.
The WS-C3850-12X-48U is very nice though too I looked very hard at it, this one would save me the hassle of getting SFP+ adapters. The only reason I am leaning away from CIsco is that they are little more a used nightmare in regards to lic and images. Rarely do the sellers show the output of system config / lic and you typically get a Base IP lic which does not support things like VLAN routing which I would not mind having. Looks like I get all Layer 3 stuff with the brocade for much less hassle.
