Anyone have experience with a Nexus 9000 running in an endless reboot?I rebooted an N9K-C93180YC-FX24 running 9.3(10). I had intended to replace startup-config with a modified version to try out a new configuration ... but mistakenly skipped the 'cp ...

I am trying to deploy QSFP-H40G-CU1M on my flock of Nexus 9300, various hardware flavors (N9K-C9372TX/PE and N9K-C93180YC-EX / N9K_C93108TC-EX) running varying versions of 7.x and 9.x, with varying results, none of them successful thus far. I note t...

BRIEF- I would like to clear all configuration statements from an Ethernet interface on an N9K (93180YC-EX), including the (4) storm-control ones. But, I am unable to do so: "Invalid command"DETAILN9K# sh run int eth1/47version 7.0(3)I7(9) Bios:versi...

Well, that makes sense, from a protocol perspective (retiring ftp / integrating into GIT)But, regrettably, I don't see a replacement for v1.tar.gz or v2.tar.gz ... rather than pull down the MIBs for each particular product ... tedious ... I would rat...

Turns out that an intermediate device, a Firewall, is intefering and presenting the illusion of open ports to nmap. I plugged a host into a Layer 2 switch which also services EXAMPLE 1/2/3, ran nmap from it, and now the output shows only the expecte...
