Simple (I think?) Managed Switch Setup Richo 08-15-06

Hi guys,

I'm a bit new to managed switches, but am looking to set one up for a
friend of mine that runs a secretarial service and manages the strata
for the building as part of that. At the moment, he has a standard
switch and all of the offices can see each other's computers. What he'd
like to do is use a managed switch (he has an ELS100-24TXM) to isolate
port 3-24 from each other (i.e. create a VLAN on each port - i think?)
and share the other two ports (1-2) with all of the ports without
allowing data across the 3-24 VLANs. Port one and two connect to the
Internet connection and a shared server.

I can set up trunking ports and/or egress ports on this router, though
i'm not 100% clear on what each does. Any suggestions would be
appreciated.

Richo.

the other local info that will be impacted - IP address assignment -
how are the local IP addresses obtained - DHCP ?
remember that VLANs build walls to contain broadcasts.
