In case of disaster, it is usually a very good idea to periodically back up the configuration of your network switches. This article lists syntax for backing up configuration to a TFTP server for different vendors.

In the syntax examples below, the IP for the TFTP is 1.2.3.4, and we're writing to the file switch.cfg.

Note that this article is definitely not complete. If you have additions to this article, please post them in the comments.

The syntax for Dell and Cisco switches is mostly the same. For N-series and PowerConnect, a summary is displayed which needs to be confirmed, which is not the case for Cisco and Dell S-series.

For Cisco Small Business (SF- and SG-series), the CLI ne ...

Enable Telnet/SSH on Cisco 300/500 switches

edited by on August 21st 2018, at 14:44

Cisco's SF/SG 300/500 series managed switches have CLI access via Telnet and SSH but this is turned off by default, leaving only the web interface to manage the switch. You can enable Telnet and/or SSH via the web interface, enabling management via CLI.

Log on to the web interface, then navigate to Security → TCP/UDP Services.
Check the Enable boxes for Telnet Service and/or SSH Service. You can check both if you wish to enable both protocols. Click Apply, which will immediately start the selected services:
Don't forget to save the configuration change to flash. Otherwise, the change will be lost after a reboot:

Disable SSL certificate warning in vSphere PowerCLI

edited by on August 21st 2015, at 10:23

If your vCenter server has a self-signed certificate, you will get a warning about this when connecting to it from vSphere PowerCLI. You can disable this warning through PowerCLI with the Set-PowerCLIConfiguration cmdlet.

Start an elevated vSphere PowerCLI (right-click, Run as Administrator).
Enter the following cmdlet:
```
Set-PowerCLIConfiguration -InvalidCertificateAction Ignore
```
Press Enter again to confirm the change.

After making the change, new connections to the vCenter server will no longer produce a warning about the certificate.
