I was troubleshooting a Cisco 3650 Catalyst switch, which is their "new" line of stackable access switch, and I can't seem to get Private VLAN (PVLAN) to work. Cisco's data sheets were contradicting as to whether PVLAN is supported or not on this switch platform. I just couldn't believe this switch won't support this feature since its cousin switch like the 3750 and 3650 were using it. As I searched further, I found out that PVLAN is supported on IOS XE 3.7E but the IOS file was a bit large (around 300 MB).
It took me roughtly 40 minutes to TFTP the said IOS file on one switch. So I decided to try to configure the switch to use FTP instead. It took me around 3 mintues to upgrade the image.
Create the same username and password on the FTP client that is configured on the switch and point the folder directory where the IOS image was saved. I've used a free FTP client, which is 3CDaemon.
This was my first SWITCH lab that I did during my CCDP studies. The topology is a square looped design, which is very similar to the triangle loop design but there's a difference where STP blocking occurs.

Create the same username and password on the FTP client that is configured on the switch and point the folder directory where the IOS image was saved. I've used a free FTP client, which is 3CDaemon.
This was my first SWITCH lab that I did during my CCDP studies. The topology is a square looped design, which is very similar to the triangle loop design but there's a difference where STP blocking occurs.
