Hi, is anyone aware of any quirks or special configurations required when connecting Intel 10GbE NICs to Nexus switches? We've run into a number of problems. Have I missed anything obvious? Details below.Setup no. 1: Nexus 4900M, two Dell R510 with d...
Is there any way to uplink a Nexus 3064TQ-32T to a 3750 stack with a gigabit connection, or do I have a very expensive door stop now?The documentation implies that the 1/10Gb ports are downlink-only, and uplinks can be created only via the QFP slots....
The ASA 5510 here is crashing frequently. We have been unable to find out why exactly this is happening, and the device is not under a service contract. The logging that is in place doesn't give any hints as to why this is happening. Since the last t...
While I still don't understand the cause of this problem, and still don't understand the specifics of flow control negotiation, some experimentation shows that I can work around the problem by either configuring all ports on the 3064 that link to 825...
I'm currently thinking along the lines of "interesting"/buggy driver and behavioural differences between the two switch models. Does anyone know if the setting for RX/TX flow control on the switches must or should match the NIC settings? I found that...
I don't think this applies. We observe this problem across driver versions, ranging from 3.9.15-k (latest CentOS6.4) over 3.17.3 to 3.18.7. The only correlation I have right now is the combination of NIC and switch.82599EB + 4900 is good.X540-AT2 + 3...
Yes, all Dell machines had their firmwares and BIOS updated to the latest available through OMSA. I also applied Intel's preboot updates, admittedly not the latest (v19 vs. 19.3).I have now hard evidence that the problem has nothing to do with teamin...
