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.

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″]



Rebooting a HPE Aruba 5400R zl2 with dual Management Modules following a Firmware Update

If you have ever seen this post Server Room – The latest you will notice we have a pretty awesome HPE Aruba 5400R zl2 Core Switch; however (at least until now), I’ve been yet to find a really simple guide which shows the best way to reboot the management modules following a firmware update. So after much research and a… Read more



Setting the Source Interface/VLAN for RADIUS, SNTP, syslog, TACACS, Telnet, TFTP and sFlow on HPE Aruba (ProCurve) switch

If you are running an HPE Aruba (formally ProCurve) switch you may come across cases where your switch (in the example above a 5400R zl2) has multiple IP Addresses/VLANs and you need it to talk to another service (in my case syslog and sFlow receivers) on a set interface. When this occurs you can use the ip source-interface command (make… Read more



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! Included in the images are J9729A 2920-48G-PoE+ J9728A 2920-48G J9731A 2920 2-Port 10Gbe SFP+ Module… Read more
