IETab: The Internet Explorer compatibility tab for Chrome
Older Cisco and HPE gear provides web interfaces that just don't work any more with modern versions of Firefox or Chrome. This isn't a massive deal: the preferred way to set up an old Cisco 3560 switch is to use the command line via a serial cable anyway. The Integrated Lights Out stuff on older HPE gear is a little more problematic.
Enter the Chrome Internet Explorer extension: IETab
To get around this, there is a great Chrome extension called IETab. Installation is simple and it works superbly!
Here it is - enabling me to use the web interface on my office 3560, which is great as I can now enable POE where I need it.
I will eventually work out how to use the CLI on the Cisco (I need some fancy VLAN stuff happening on there) but for now, we're golden.
