Data Center Bridging is enabled.  DCB is not fully supported by the 8024F switches.   This causes standard port flowcontrol to be disabled.  Disable DCB is in the EQL GUI, under Group Parameters.   This will resolve the issue. 
I configured two Powerconnect 8024F switches for use with Equallogic. Firmware version on swithes is 5.0.0.4 and on the Equallogic the firmware version is 6.0.1. I stacked swithes together and I use 6 ports on every switch for that. I configured ports for use with equallogic and servers accessing that equallogic. I created seperate VLAN, set mtu size to 9216 and enable flow control. Here is the problem: I got an error or I should say Warning on Equallogic saying that: Ethernet flow control has been disabled on one or more interfaces. I checked severeal times the configuration but could not find any problems. Any suggestion what could be the problem?   Thank you for the help! Rafko
