Firepower 1010 Review
KB ID 0001666 What Is It? I’ve been trying to get my hands on one of these for a while. So thanks to my employer for sending me one to take a look at. The Firepower 1010 appliance is aimed at Small Office / Home Office, and possibly Small Remote Branch offices. But like its predecessors it will probably get put in EVERYWHERE because it’s ‘cheap’, (Note: for cheap, read possibly under-specced* and the wrong...
Brocade Switches Getting the Serial Number
KB ID 0001665 Problem If you have fiber channel switches, (regardless of the vendor,) scratch the surface and underneath it’s probably a Brocade. (Unless it’s a Cisco Nexus then you are in the wrong place my friend, move along!) e.g an HP StorageWorks 8/8 SAN Switch (Yeah it’s a Brocade 6505), or an IBM SAN24B-4 Express Fabric Switch (you guessed it, Brocade). If you need to get the serial number for them,...
IBM Storwize: Get The Serial Number
KB ID 0001663 Problem I’ve got a client that has a couple of Storwize V5000 storage arrays. I needed to get the serial numbers for them today, but I could not find them in the GUI? Solution As usual things are much simpler at command line, SSH into the storage array and simply use the following command; lsenclosure Note: As you can see, I’ve got one Controller (with the cans in it,) and one expansion shelf. The first part...
Cisco ASA – Update Activation Key (From ASDM)
KB ID 0001662 Problem I recently did a post on adding extra licences to AnyConnect, (with the current surge of people working from home). I exclusively work at command line, so when I was asked how to do the same in the ASDM I had to go and check 🙂 Solution Connect to your firewalls ASDM console, then navigate to > Configuration > Device Management > Licensing > Activation Key > Enter you new Activation Key > Update...
Get Free Cisco AnyConnect Licences For COVID-19 Homeworkers
KB ID 0001661 Problem Cisco released information on their blog a few days ago to say that they would be offering free Umbrella, Duo and AnyConnect Licences to customers in the wake of the the COVID-19 outbreak. Thats great news, but there’s no information on how to get the AnyConnect licences. It just says speak to your Cisco partner. As I am a Cisco partner I was confused, and it seems my colleagues were also. So I contacted...

Powershell: Get Folder Size ‘Quickly’
KB ID 0001660 Problem Right clicking a folder and selecting properties is usually how you would see how large a folder is. Which is great, but if your folder size is HUGE (i.e. many terabytes) then this takes ages! Solution If you use PowerShell you can get the figure considerably quicker!

Cannot Recreate Azure AD ‘Local’ AD Connector
KB ID 0001659 Problem While trying to fix another Azure AD Replication problem today I managed to delete one of the connectors (the one for the local ‘on-prem’ Active Directory). In an effort to ‘recreate’ it, I ran the ‘Microsoft Azure Active Directory Connect’ and went to ‘Customise the Synchronisation Options’. Unfortunately I got this error; The forest {forest-name} cannot be added...
VMware Edge Gateway VPN to Cisco ASA
KB ID 0001658 Problem I was asked to setup a VPN to help out a colleague this week. When I had a look, one end turned out to be an Edge Gateway, I wasn’t that concerned, I’d done similar things in my prior role, I just didn’t have access to the vCloud or VMware at this datacenter. Depite my best efforts on the ASA, the tunnel refused to come up, it took a little looking ‘under the covers’ to accurately...
