This is the second and last part of a small blog series about Cisco’s brand new UCS M5 series. In this blog: C-Series and GPUs.
Record-breaking performance in a dense 1RU form factor for a wide range of workloads including virtualization, web, collaboration, cloud, and bare metal applications
Unrivaled performance for a wide range of enterprise workloads including big data analytics, collaboration, databases, virtualization, and high performance applications
Last week, Cisco announced the brand new Cisco M5 blades and services. In this post a brief summary about the technical details.
There is a overlap between selling and supporting M4 and M5, this overlap is at least 12 months. End of Sale of UCS M4 is not before calender year 2023:

As you might know, creating a VSS on Cisco Catalyst 4500-X switches is pretty easy and there are many many guides with information how to do this. I think THIS guide is one of the best to do this.
However, there is one additional note which is not mentioned on that (and other) blogs if you are planning to use multiple Catalyst 4500-X VSS clusters. This is related to the switch MAC address.
By default, all MAC addresses used by the Catalyst 4500-X VSS cluster is automatically generated and is based on the VSS domain ID. But what does this mean?
If you’re planning to use multiple VSS clusters in the same network and in the same VLAN(s), you’ll end up with duplicate MAC addresses. I’m sure I don’t have to tell you that this is something you don’t want: it brakes a lot of things in your network.

There are many configuration guides on the Cisco website with details about configuring RADIUS and TACACS+ on a Cisco Firepower Chassis Manager. See this link for the configuration guide for 2.0(1).
In this document, you can read the following comment:
| Remote User Role Policy | Controls what happens when a user attempts to log in and the remote authentication provider does not supply a user role with the authentication information: |
But… it’s very hard to find what attributes are needed to assign a user the administrator role.

This blog is about recent updates on the Cisco Nexus 9000 series datacenter switches. This describes my view on the switches and technologies.
Nexus 9000 series is currently Cisco’s flagship on datacenter networking. This is today and still for tomorrow. Mounting the Nexus 9000 switches should be the last physical and configuration work you’ve done in the (future?) datacenter. All upcoming tasks (aka.. Configuring and provisioning the switches) should be done automatically by any automation tool. We have to move from our traditional networking tools to more automating and orchestration tools from today on. Nobody wants or has time to manually configure all these switches like in the old days.
The Nexus 9000 series switches are ready to achieve this with many on-the-box features like automation with PoAP, REST CALL with NXAPI and the “unix-way of management”. This, to program and configure the network / fabric.
