Update: As part of dealing with a quirky firmware update issue, I went into the web interface and did a warm failover to flip-flop the managment units (by switching the Unit Type from "StackMember" to "Management" on one of the two switches) and after applying the changes and reconnecting, I'm now getting full bandwidth throughput across the entire network!  Something was apparently awry in the communication between the two stack members? At any rate, the stack seems to be working as it should now.
Hi Folks, First of all, I am 100% new to the Dell switching model. Secondly, I've only been with this company a month and have been putting out more fires than any individual my age should have to!My latest 3 alarm fire is that I am getting VASTLY different internet speed tests between two stacked 6248's. If I'm plugged into 2/g29 I get 48Mbps both down and up, if I'm plugged into 1/g29 however, I get 10Mbps down and .41Mbps up!? These two switches have the same software (3.2.1.3) can anybody see anything glaring based on the running config posted below? Note: The Firewall is connected at 2/g33 and there is no QOS on it's interface. Thanks!
