Another unexpected Zone Protection Profile doing it’s thing – in this case sending a ping from an end-user device (such as Windows/macOS computer) to an IP interface (gateway) on a Palo Alto Networks Next Generation Firewall was coming back with a response, but requests from HPE ProCurve (Aruba) switches (2920/2530) appeared to disappear into oblivion with no response. A little… Read more

Brief guide to (common-ish) HPE Aruba Fibre Optics
Not meant as a complete in depth guide but certainly enough to point you in the right direction here’s my list of the most commonly seen (from my point of view) HPE Aruba (e.g. the 2540, 2930F, 5400R series) fibre optics and their respective part numbers: The format is effectively <Speed> <Fibre Type> <Maximum Range> – <Part Code> 1Gbit Multi… Read more
HPE ProCurve/Aruba turn off — MORE — (aka paging)
When running CLI commands against an HPE Aruba (previously ProCurve) switch that have long outputs you have likely encountered the line below. — MORE –, next page: Space, next line: Enter, quit: Control-C Although handy – on occasion you might need to turn this off.

Does the HPE Aruba 2530-8G switch come with 19″ ears? Yes!
Normally the little 8 (well 10 if you include the ‘uplink’ ports) port switches we buy end up under a desk or on a shelf but for a one off we’ve got one going in a comms cabinet. Quite luckily the HPE Aruba 2530-8G come with the ears in the box to do this (I recall seeing some models of… Read more
Aruba (by HPE) 2530 – pictures
Today we received a new HPE Aruba 2530-48G-PoE+ (J9772A) which will be going in a new annex building. While not overly interesting I thought I might post the photos of it in the gallery below. ” order_by=”sortorder” order_direction=”ASC” returns=”included” maximum_entity_count=”500″]

Mitigating SSH Weak MAC Algorithms Supported and SSH Weak Encryption Algorithms Supported on HPE Aruba-OS Switches
Having recently setup OpenVAS (something I will likely blog about in further detail soon) I have found out that the default out of box deployment of Aruba-OS (formally ProCurve) supports a number of insecure SSH Algorithms with messages similar to the ones below logged even when running the latest firmware releases (YA.16.03.0004 on the 2530 series). SSH Weak Encryption Algorithms Supported… Read more
Flashing lights and HPE ProCurve/Aruba Switches (chassislocate)
When working with a lab full of HPE ProCurve/Aruba switches (or you just want to know who is who in a stack of switches) the chassislocate CLI command comes in really handy by either blinking or holding solid the blue locator light. See the screenshots below for a little more info. ” order_by=”sortorder” order_direction=”ASC” returns=”included” maximum_entity_count=”500″]
Aruba (by HPE) 2920s – pictures
It’s that magical time of the year where…new network switches arrive! Given that the new Aruba branding has taken full control of what was ProCurve I thought I should post some photos of the new paintwork. Happy to say the colour black isn’t half bad!
