I have a Cisco C93180 with some unused QSFP ports. All the 10 Gbps interfaces are occupied connected to workstations with 1Gbps NICs. So, they negotiate down from 10Gbps down to 1Gbps. But we need to connect a few more workstations. We'd like to us...

I just hired on with my company and they've put me in charge of their Cisco Unified Communications Manager (on version 11.5.1). Someone else set it up prior to me joining the company. I have zero prior experience with this but so far have managed t...

I believe I have a bad Cisco Nexus N9K-C92160YC-X. I would like it if someone could confirm it for me before I submit an RMA. I received this switch brand new from my supplier with a blank configuration. It booted up successfully the first time I p...

The full model is C93180YC-EX. I'm not seeing anything that exactly matches that model in the link you provided. EDIT: It's in there. But the C93180LC-EX is in there. I figure that's as close as we're going to get. It certainly appears to support...

@balaji.bandi I was able to reload the switch and it appears the messages have stopped. I suspect that, since I haven't upgraded the firmware yet, they are likely to return at some point. I had seen the bug report you linked but wasn't totally sure ...

@balaji.bandi thank you for your response. The switch is showing version 7.0(3)I7(3). Looks like Cisco's recommended version as of today is 10.2(6)M or 9.3(13) if I want to stay within the 9 series.It is indeed part of a vpc and so I believe I migh...
