I was just given a Cisco Catalyst 2950/ 24 port switch. The first 22 ports say 10/100 and the last 2 say 10/100/1000. The guy who gave it to me says you can buy a GLC-SX- MM thing a maguey and make the entire switch 10/100/1000. I this true and if so where to I go to find out more. Cisco has basic info but dent mention if it just does 1 port or all ports. I only have basic networking knowledge. Most of my network is 10/100/1000 when possible. Things like apple tv are 10/100. My other 3 switches are 10/100/100. In real world use will this switch do ok or should I just upgrade to switch with more ports. My 8 is full.

Nothing will change the 10/100 ports to 10/100/1000.

Thank you for the fast response.

Unless you want to learn Cisco IOS, those old 2950s are pretty much scrap.  They're noisy, they drink power, and they're slow.  Not terribly reliable, either.

 

I had a few at work, and they even sucked running printers.  They're 90's technology that should be left in the 90s.

Thanks for the input. Sometimes free is not a good as it can be.
