1G is dead. What Cisco switches have no 1G ports?

[cmccane]

Neither me or my org would pay money for any switch with 1G ports. Those days are in the past. Which switches offer up to 48 nbase-T with full support for 10G over copper for all ports?

Cisco 9300X does.

Very brave to put the foot down. 

Let us hope that no one is going to buy a client that requires 10 Mbps.

Again cost also matters, if the budget is not issue, you have different models available with combination.

Question to ask here is does your end point ready with 10G connection ? do they really need 10GB speed ?

when you design network, we need to address all these issues.

[cmccane]

Workstations for video content benefit greatly from 10Gb. Content creators these days expect centralized storage at the speed of their Thunderbolt 4 M.2 enclosures. 10Gb can deliver about 25% of that speed but it's 1Gb Ethernet thats a real no-go.

Most models of Macs offer built-in 10Gb ports and current-gen Windows PC's are up to 2.5Gb. To really reach the level that creators want today, the path is to 25Gb Ethernet - that's what gets you parity with Thunderbolt 4 enclosures.

Its true that typical office users will be fine with 1Gb Ethernet for some time but depends on how much companies are diving into making video content. I don't believe anyone is going to be mounting AI models over the network due to latency but in some situations corporate workers may need to move AI models around which would benefit from 10Gb speeds.

Hello @cmccane 

AS @Flavio Miranda says, Catalyst 9300 series offers models with 48 multigigabit (NBASE-T) ports that support speeds of 1G, 2.5G, 5G, and 10G over copper.

Hello @cmccane ,

>> Neither me or my org would pay money for any switch with 1G ports. Those days are in the past

Well more a marketing slogan that something that really meaninful:

yesterday I moved some big files over  1GE

ftp> lcd
Local directory now C:\CML2024-iso.
ftp>
ftp> put refplat_p-20240322-supplemental-iso.zip
200 Port command received
150 Opening data connection
226 Transfer complete
ftp: 6534735879 bytes sent in 66.96Seconds 97587.26Kbytes/sec.
ftp>

I have been to able to transfer 6GB file in 67 seconds.

I think this is still acceptable nowdays, isn't it ?

Now for you question other colleagues have answered to you.

Cat 9300 X may be the right product for you.

But be careful about buffers if you want to put it in a server farm you shoud consider Nexus 9300 family instead.

9300 X should have greater buffers in comparison to other cat9300 models, per port or per ASIC but of course the Nexus 9300 family is even better but they need to deployed in pairs called VPC.

Edit :

10 GE on RJ45 on Nexus 9300

there is an issue with some models that have only SFP ports they are 1g/10g/25G but the SFP 10 GE T have special requirements

I get what you are saying about "acceptable nowdays". Sure, you can wait 67 seconds for a 6GB file. Some of my Final Cut Pro files exceed 100GB so 10G is my only option, unless I want to waste time copying instead of editing the video. Its great to see Cisco rising to the new generation of multi-gig.
