The max VLAN count per FI looks to be 32000, and 64000 when in optimized mode. With ACI we have a LOT of VLANs on some vNICs so we are approaching the 32000 limit.
Is there any downside to enabling the VLAN port count optimization? And will it co...
I'm trying to better understand how the default QoS behavior in UCS interacts with newly configured QoS policies.
1. My understanding is that the default behavior out of the box is that under congestion, FC traffic will get 50% of bandwidth and has...
Got kind of an odd situation where there is a block of CIMC management IPs for use, and right in the middle of this block we have an IP conflict that can only be resolved on the UCS side.
Is it possible to remove an IP from the block, or to split t...
I went through an issue earlier this year on a 3850 stack where we were trying to enable jumbo frames on a single L2 VLAN for a UCS environment connected via port channel to upstream switches. If the interfaces are both on the same UCS FI, jumbo work...
I'm having trouble trying to integrate (what I think should be) a simple if/else statement in a workflow. The documentation on this seems pretty lacking.I created a new workflow called ifelsetest with a user input of catalog as "SelectOS". I want t...
Thank you for the information.
So is it safe to say that VLAN port optimization does not affect anything upstream, including ACI? From the upstream switch perspective, nothing will appear to change?
Thanks Evan that is very helpful.
With respect to my last scenario and your last answer, in order to not impact existing servers with Best Effort when implementing a new QoS scheme other than default, we would need to first put QoS policies in plac...
Can't figure out how to edit the original question. Meant to add, the person who fixed the 3850 believes it was related to auto qos but can't be sure and of course we have no notes or documentation on it.
You were right. I changed the input to admin input and selected the entry, and the output is actually a numeric ID so it wasn't matching up with the text. I modified the match statement to the number and it worked fine.Thanks!
This gives the same result as not using the ${} notation. It seems to always evaluate false.Maybe it is true that the SelectOS variable actually contains some kind of numerical ID. Is there an easy way to check what the value of this variable is wh...
