We recently deployed SG300-28 to replace an old 3Com switch.
RVS400 router and all workstations and server are plugged into the SG300 switch.
Windows 7 workstations are unable to obtain IP addresses from the server which is also plugged into the switch.
If however, we plug in the worstations into the 4 port switch on the back of the RVS4000 (the router), they get IPs from the server no problem.
This worked just fine with the old 3Com switch so we filed it under the Small Business Switches category.
Any comments/tips appreciated! Thanks in advance!
Please make sure the SG300 switch is running latest firmware 220.127.116.11 , also this is new code so please factory reset the switch after the upgrade. If you need assistance in upgrading please call Cisco Small Business Support Center @ 1-866-606-1866
After the upgrade please repost how these devices are connected and the configuration of your RVS4000 & SG300 series switch. Are you using RVS4000 for your DHCP server?
Also make sure your RVS4000 is running latest firmware as well.
