I understand the onvious that the interfaces are different. To give a little background I am in the process of creating a LAN for 200-250 nodes. This is housed in 2 buildings connected by fibre that is switched to ethernet before it hits the cisco switches. I would like to have a 3550-12G at each location with 8 2950G 48 port switches located on each floor with 3 in the server room. Each of the switches would then be connected via a GBIC to the 3550. Can I not use the 3550-12T because the 2950G use GBIC's? If not can i use the 3550-12T? Also does everything else seem ok with this design? I havent worked with vlans / L3 routing other than test in the past so this will be a big learning experience for me. I am also hoping that the Fibre converter connecting the 2 buildings doesnt make issue with the cisco equiptment.
3550-12G and 3550-12T has 12 ports can run at 1Gbps.
The key difference is 3550-12G has 10 Gigabit ports (1000BaseX) running fiber gbics, and two gigabit ports running copper (1000BaseT on board). While the 3550-12T has 10 Gigabit ports running copper (1000BaseT on board) and two gigabit ports running fiber gbics(1000BaseX).
Both switches have a 24Gbps backplane and can run EMI software to do layer 3 routing.
Whether to use 12G or 12T depends on what GBICS you are planning to use on the access layer 2950 switches, as well as distance between the access (2950) and distribution (3550) switches. Note the gigabit over copper can run no more than 100m (328ft).
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
j ai une question j ai achete un routeur cisco 887VA-k9 , je le configuré avec la configuration ci- dessous
si je le lier avec mon pc portable sur l un de ses ports directement ça marche toute est bien ( la connexion internet + m...
