not knowing your specifics i would separate servers in their own vlan. also I would separate the devices that create a lot of trafic from the rest of servers and workstations in their own vlan. and finally move workstation to their own vlan or two. you have 3650 and that gives you lots of...

did you set switchport trunk encapsulatiom dot1q on a trunk port on cisco? also I would create another vlan on booth devices instead of using vlan1

The default port for IMAP is 143 and the default port for IMAP over SSL is 993 blocking these two ports you block most of IMAP traffic

I believe cisco provided QoS MIBs and any decent SNMP collector should be able to handle it

in production we use netscreen ssl vpn boxes and everyone just loves them: admins and users. the term serv client (java or activex) is nice. It uses native windows client when possible and emulates it when it's not available. the speed is very good as long as the connection speeds on both ends...

If all you need is to move web servers and mail to a new IP block and you have some time to prepare. You can change TTL (time to leave) for the domain you move. Make it, for example, 1 hour. You need to give it some time for a change to propagate thru the internet tho. At least the half of the...

simple but might be not very flexible aproach is to split your network to 2 VLANs with 2 different gateways for each vlan I do not know if sonic firewall is capable of load balancing between two uplinks. If it can load balance I would skip the round robin and would keep each session on the same...

Actually, Yahoo and I think most of the other web based emails providers do include sender's IP address in the headers. It looks something like Received: from [x.x.x.x] by webyyyyy.mail.yahoo.com via HTTP;
