VLAN based QoS on a HPE comware Switch

Good afternoon my fellows! There are many ways to configure quality of service (QoS) on a switch. First we need to classify what we want to be on a higher priority. You can classify an access-list, vendor-mac-addresses or just everything/any. In my case I wanted to prioritize a whole VLAN (ID 17 in my case). … Read more

802.1x, MAC-Authentication and VLAN assignment at ProCurve/aruba Switches

Phew… it cost me a lot of time and headaches to establish the scenario of 802.1x and mac-authentication with dynamic VLAN assignment on a ProCurve/aruba Switch. The NPS logs set me on the wrong track… I used VLAN 1 for 802.1x, VLAN 2 for MAC-Authentication and VLAN 999 for the dead VLAN. Don’t forget to configure … Read more

How to use 802.1x/mac-auth and dynamic VLAN assignment

Hello guys! Today I want to show you how to secure your edge-switches with 802.1x and mac-authentication fallback in combination with HPE comware-based switches. The 802.1x protocol is used for network access control. For devices like printers, cameras, etc. we will use mac-authentication as a fallback. We will also use dynamic VLAN assignment for the … Read more

Virtual Router Redundancy Protocol with Comware Switches

Virtual Router Redundancy Protocol is easy to configure on a comware switch. Each device needs an IP address within the subnet, after this you can configure a virtual-IP for the VLAN-interface: CoreSwitch1: interface Vlan-interface1 ip address 10.0.0.135 255.192.0.0 vrrp vrid 1 virtual-ip 10.0.0.54 vrrp vrid 1 priority 120 CoreSwitch2: interface Vlan-interface1 ip address 10.0.0.136 255.192.0.0 … Read more

Spanning-Tree between HP Comware and Cisco

In the past, I had many problems with a heterogene infrastructure containing HPE 5000 Comware devices and Cisco Catalyst switches. I couldn’t get Multiple Spanning-Tree (MSTP) on the run (same revision number, same case-sensitive region-name). So we decided to go on with Per VLAN Rapid Spanning-Tree. But this also didn’t work, also no other VLANs that … Read more

Using 40GE QSFP to 4x 10GE SFP+ splitter cable

Today I was very frustrated when I connect a 40GE QSFP to 4x 10GE SFP+ splitter cable to a HPE FlexFabric 5700 48G 4XG 2QSFP+ switch (JG894A). I received the following message: [HPE]%Jan 8 19:02:19:652 2011 HPE OPTMOD/4/MODULE_IN: FortyGigE1/0/54: The transceiver is STACK_QSFP_PLUS_4SFP_PLUS. [HPE]%Jan 8 19:02:50:826 2011 HPE OPTMOD/3/TYPE_ERR: FortyGigE1/0/54: Transceiver type not supported! First reaction: … Read more

Build-up a redundant aruba wireless infrastructure

Currently I’m evaluating the aruba controller and access-points as a new product in my company. My goal was a high available system with two wireless controller and two access-points. I created a visio graphic for this, it also contains the ip addresses of our laboratory: I’m using two aruba 7008 RW (Rest of the World) mobility controller … Read more
