HP Networking – Tracing Networks and Locating IP addresses
KB ID 0001110 After not touching one for a couple of years, I was back on HP switches recently, and I had to map out a clients switches. Now I could have used some software, but they didn’t have SNMP enabled so, I had to ‘re acquaint’ myself with LLDP. For a basic LLDP View of attached devices.

HP Networking ‘ProCurve’ – Trunking / Aggregating Ports
KB ID 0000638 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 second fiber...

HP and Cisco – VLANs and Trunks Confusion!
KB ID 0000741 Problem When I first started in IT, I went and did my Cisco CCNA. So I learned that to connect Cisco switches and pass VLAN traffic between them, I needed to create a ‘Trunk’ to pass the VLAN traffic. Fast forward a few years, and I now work for an HP reseller. Very early on I came to realise that what HP called a ‘trunk’ was very different from what I had been taught. Below is an article I did a...
Setup an HP 1800-24G (J9028B) Switch
KB ID 0000800 Problem Essentially you can unbox this switch, plug it in and it will do what you want (unless you have VLANS, or trunks (port-channels)). Which is what my client had done, but I needed to get on the web console and have a look at what was going on, and there is NO CONSOLE socket on this unit at all. Solution 1. Don’t bother looking in DHCP, it’s NOT set to DHCP by default. From the factory the switch will have...
