+**What Went Wrong?**
+\\
+\\
+Now, this is not going to affect everyone, but in our systems we sometimes have to prove redundancy by taking down an interface, letting a device detect this and watching the system automatically switch. Sounds simple enough, but it seems that using a simple <color #ed1c24>ifdown</color> or <color #ed1c24>ifup</color> does not cause a redundancy switch, you need to do a bit more.
+\\
+\\
+To properly take the interface down, so that it is recognised as being down from a 'link'perspective, you must use the following syntax:
+\\
+\\
+<color #ed1c24>ip link set eth1 down</color> (obviously use your interface name, not mine)
+\\
+\\
+And inversly:
+\\
+\\
+<color #ed1c24>ip link set eth1 up</color>
+\\
+\\
+This will ensure that the interface goes fully down, and that other devices can recognize that the interface is down.
+\\
+\\
+I sincerely hope this saves you some pain :)
