What is the meaning of E, L and F in C1000 series switches?

[Md. Shahariar Rahaman]

I've noticed that most C1000 switch models end with "L". However, I'm unsure what the "L" signifies. Additionally, some switch models also include "E" or "F", and I'm curious about their meaning as well. Could you please explain what these letters indicate?
And also I need to know difference between C1000 and C1000FE.

I already checked this. But after that I can't understand something. That's the reason i did this post. If you explain this please do this. It will be helpful for me. Thank you for your reply.

I'm pretty sure the L = LAN Base.  I think E = IP Services and not sure about F.

the -FE models will be FastEthernet
instead of 10/100/1000 interfaces these only have 10/100 interfaces
see rightmost models in Catalyst 1000 Series Switches - Cisco
and of course the datasheet: Cisco Catalyst 1000 Series Switches Data Sheet - Cisco
