Ethernet speed

It depends on the switch, but generally the ethernet speed doesn't depends on the T1 line. However, if devices connected to switch are accessing all to internet,m the 1.54M capacity will be shared between every device, so this is the bottleneck when connecting to internet.

Hope it helps.

If the devices are connecting to each other they will communicate at 10m. If they are sending traffic over the t1 that will go at 1.5m.

Sorry, I should have mentioned the internet connectivity for all the devices connected here...

So, if the T1 is being shared all the ports, that leaves (1.54/24) or 64k for each port. However, we have each sw port config'ed as 10 M port.

Unless your switch has qos it will try to randomly share the t1. So if only one port is using it, it will get the full 1.5.

so the other ports would be waiting for one port to relinquish the control?? That is too much.. most switches have auto-qos, right??

In an unmanaged switch it will be random. But most usage is also random, so it works out, except in some cases of heavy usage ( large uploads/downloads).
Your internal speeds will not be affected, but internet access will always be limited to your max T1 speed.


I hope this helps !

It does not matter if the ports are configured as 10 meg or gigabit. You are limited to 1.5 of the T1. You cant expect to get more just because your switch ports are capable of more.
Each port is CAPABLE of 10meg that does not mean it will always be running maxed out at 10 meg.
Your T1 is capable of 1.5M and it is unlikely that it will be permenantly maxed out or stressed UNLESS you are using it for large upload/download. IF used for mail/browsing and applications you wont notice any degridation at all I would think.
