Can we connect directly to isp from a cisco L3 switch ?

By absayyid ·

I am a network engineer and scenario here is quite diff from other place. I am connectin LAN's located in 10 diff islands. I have two routers. One in capital island and one in mainland. They provided L3 switch for other island. Bsnl is the isp and they told the they will give copper wire connection to the locations in these islands. Can we connect a copper wire connection to the L3 switch and can we connect this switch to internet directly. Or do we need the capital city router to program the other island's L3 switch to access the internet. What can be done ?

If copper = high speed Ethernet

then the ISP is probably right. Some ISPs do provide this service. I know it seems odd for a layer 3 switch to be on the edge of the network (even from my limited perspective), but that is one way they can indeed provide your internet connection. Probably with a GB interface converter.

You can get a lot of general info even from the first page of hits:

And if you don't yet have documentation for the Cisco switch, get it's exact model number and look up the docs at the Cisco site.
