FortiGate Sub Interfaces (VLAN Trunking)
KB ID 0001772 Problem I was asked by a colleague at work the other day, can we replace the Cisco firewalls with FortiGate firewalls for a client? As a business we are heading towards Forti, but before I said yes I wanted to know what the firewall was actually doing before I said yes. On closer inspection the firewall in question didn’t appear to be doing anything too scary, but I did notice that the LAN interface was...
Cisco IOS: Ether-Channel Trunks
KB ID 0001533 Problem This is a subject that every time I need to create an Ether-Channel I end up checking beforehand, so it’s about time I wrote it up. We are combining two different things, an Ether-channel, (an aggregation of links) and a Trunk (the ability to carry many VLANS). If you are NOT from a Cisco background then you might want to read though the following post first to avoid confusion about the world...
HPe Synergy 12000 MPIO QSFP to 10GB SFP Setup
KB ID 0001495 Problem I was recently involved in deploying an HPe Synergy 12000 Frame. And the network connections from it were ‘a little unusual’ so I thought I’d document that here, to save anyone else the problems I had.

Cisco IOS – An interface whose trunk encapsulation is “Auto” can not be configured to “trunk” mode.
KB ID0001167 Problem If you try and change a ports status, to make it a trunk port, you may see this error; Petes-Switch(config-if)#switchport mode trunk Command rejected: An interface whose trunk encapsulation is “Auto” can not be configured to “trunk” mode. Trunk Settings I don’t know if this is a throwback to when we had ISL trunking and 802.1q, but you need to specify the encapsulation before you can...
Audi A6 – Luggage Compartment Fuse Box Location
KB ID 0001161 Problem I know it’s not the usual site content, but PNL was born from my dislike of vendor documentation, and crappy documentation is not limited to the world of IT. The 12v power socket in my A6 wasn’t working, this was probably because there was a 1p coin stuck in it that took a lot of fishing out, I assumed the fuse had blown, and put up with it for a while. When I finally got round to sorting it out...
