I am troubleshooting QoS in relation to VoIP traffic and finding it hard to understand how the queues, queue-sets, thresholds, buffers and the CoS and DSCP mappings to queue's/thresholds on the 2960X switches actually work. Is there a way to view wha...

We have two core N9K switches running HSRP on them. We have an upcoming project that is requiring us to upgrade the software in order to support for HSRP instances. This is bringing up a unique scenario that I couldn't find too many resources on. Do ...

I am a recently new user of Cisco Modeling Labs and for the most part love it. That being said, I'm not sure if I have something incorrectly configured or if this is a true bug in the software. I am using two NXOS 9000 as cores that are configured as...

It is vPC and I had done a small amount of reading on that but wasn't sure if we were going to run with that or just simply do a standard upgrade and run with the reboot of each switch individually. Possibly using ISSU would also eliminate any potent...

Thanks for the suggestion, I will bring it up over there.

So I have all but confirmed that either I don't know how acls work, or CML is not accurately using them. I basically told all traffic to be blocked to a specific VLAN interface and traffic is still allowed through. In addition to that, it appears tha...
