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,...
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 model, 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...

HP – Switches The IP (or subnet) Already Exists
KB ID 0001176 Problem I 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. HP2510-24G(vlan-1)# At first I though the switch was complaining because the IP was remaining the same, I...
