I quite confuse the difference between "Frame-Relay-Switch" and "Layer 2 switch"
Are they a switch?
I assume that
1."Layer 2 switch" learns MAC-Address and they forward packet based on MAC address they've learned.
2."Frame Relay switch" they learn DCLI and forward packet based on DLCI.
As I understand, A Switch is 10/100/1000 Mbps. It should be faster than Frame Relay Switch.
Why we still use Frame Relay switch today?
Thanks for comment.
