Normally we use Proline or Cisco brand SFPs but I'm considering trying some Startech ones for an idea I had. We have some areas of old OM1 fiber that I'd like to get running some 10G links over to the more remote areas of our property, and the about...

I have a 4431 that's running a really old IOS. I seem to remember in the past some of our layer 3 engineers have said they were upgrading it but apparently it has had some issues and always rolled back to the old IOS. None of those engineers are wi...

A number of years ago when we rolled out our 3650 switches we encountered the issue with ipdt (ip device tracking) which sends out fake arp requests with a source of 0.0.0.0 that seem to upset industrial automation devices like HMIs (PanelViews) and ...

Yes I already understand the implications. This was not intended as a long term solution. It was to extend some 10Gb to some places that would use it. I always use dual links back when the switch can support them and if I'm testing something new I...

Well the 9120 at least can join a mobility express controller running on a 3802. I assume the 9130 could as well.

As seems the norm I appear to have found a guide that explains it after asking the question. https://www.labminutes.com/blog/2016/04/cisco-isr-4000-upgrade-guide-3x-denali-162I guess if that's the best route I'll see about requesting one of the othe...
