But this also didn’t work, also no other VLANs that … Read moreSpanning-Tree between HP Comware and Cisco

How to build an IRF-Stack with HP Switches 5xxx

IRF (Intelligent Resilient Framework) is an innovation from H3C. Hewlett-Packard has acquired the H3C switch-technology to build their new 5xxx series.
