Aruba / HP Switches Clear Interface Counters

KB ID 0001519 Problem I was looking for a way to clear (zero) ALL interface counters, (in my case on a 5412-Zl2).

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. I was connecting to an HP/Aruba 5412 switch so my cables were all HP/Aruba (to be on the safe side). What you can see (above) is the MPIO Cable (K2Q46A P/N 800867-001) fixed onto the left (and...

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. The first thing I learned, was there’s no dedicated stacking cable for them. They simply use a 10Gb...

HP – Switches The IP (or subnet) Already Exists

KB ID 0001176 Dtd 16/04/16ProblemI was changing a clients LAN subnet this week, (dropping the mask from /24 to /16). When I attempted to change the management IP on the clients HP switches this happened; HP2510-24G(config)# vlan 1 HP2510-24G(vlan-1)# ip address 10.0.0.250 255.255.0.0 The IP address (or subnet) 10.0.0.250/16 already exists.

HP Networking – Tracing Networks and Locating IP addresses

  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-Switch-1# show lldp info remote-device LLDP Remote Devices Information LocalPort | ChassisId PortId PortDescr SysName...
