Stacking (VSF) Aruba Switches

KB ID 0001492 I noticed some shiny Aruba switches on the bench today, they were for a job my colleague is working on. (Note: Each switch in a stack should be the same, so these will need two stacks!) I work on the occasional HP/Aruba core switch, but it’s been a while since I did any work on distribution switches like these.

HP Networking ‘ProCurve’ – Trunking / Aggregating Ports

KB ID 0000638 Dtd 24/07/12 Problem I was lending a hand this week, while my colleague swapped out a lot of switches. I don’t usually deploy a large number of HP switches, so I was surprised when we installed a chassis switch and after patching the fiber links, the Cisco Catalyst switches all got upset and we lost three out of four ping packets. I (wrongly) assumed that STP would be enabled, so I wandered back and pulled the...
