When we cycled our ISE 3.3p4 deployment for p4 updates, specifically when cycling the PSNs our network took a big hit that took about a week to fully recover from. We are still in a bad way since what we've found/identified in our environment is stil...

Does anyone know/have links to design/engineering guides for DHCP snooping and Dynamic ARP inspection for IOS? I've found implementation guides which don't seem terribly in depth.Environment is metropolitan/campus area network with over 1000 L2 switc...

How to see what ROMMON variables are set while in a working 9K IOS-XE CLI? Remember sh ver no longer works on these.Based on reading below links, it appears that 9K devices no longer have the ability to show the ROMMON boot variables from IOS CLI. ...

We migrated to RSTP long ago with normal/expected tweaks. I've never taken the time to review things in detail because the end result was the same thing STP did decades ago, prevent L2 loops. However we recently noticed slow convergence times durin...

Arne, can you share the TAC case number for what you mention seeing? We seem to see this in our production environment. We've found some performance improvements with our ISE configuration that have helped quite a bit, but still see some of it. We...

I will see what we can do, and again thank you. Also new data from yesterday's testing. If we delete the NAS from ISE, so no session with any PSN since we do not use default NAS. The switch will not correctly perform fallback for dead server on ...

Arne Bier, thank you for all the input and suggestions. I must admit that trying to let the young pups take the reins has put me at a disadvantage with ISE 3.3. Retirement potentially on the radar after decades of CCNP and Ciscoisms and "turning over...

Understand that we have gotten the problem slowed down enough, and people "self fixing", that we are having dificulty "catching" this. The following is based on an extremely limited sample.-Why are endpoints receiving an EAP Failure at all: unsure, h...

For others who may drop in on this thread because of similar questions, the most complete data we've recently found is for the cat 9300, IOS 17.6x here. However, it seems to still leaves questions about dual sups and binding backups on flash, since...
