teading the docus for the 2821 there are different modules available:
our (new) layout should look like
Internet(4Mbit) | | 2821 ---- internal-backbone (16Mbit)--- other sites | | 3560 | | | VLans
What are the differences between 1fe and 4esw for the above setup? If i understand the docs correctly, the 4esw is like the 3560 (routing in software between the other ports and local VLANS, but that shouldnt bee an issue with 20MBit)
Are there any other issues?
