All major server manufactures have a built-in baseboard management controller (BMC) for remote server management. These are great tools for onboarding a server and maintaining the server throughout its lifetime. Most of my day to day experience has been using the Cisco IMC, Dell iDRAC, HPE iLO, and IBM IPMI. Some of the server vendors require an additional license to unlock the full features of their remote server management such as Dell iDRAC Enterprise and HPE iLO Advanced licenses, while other server vendors include all feature capabilities by default.
Hello loyal LP blog cats. In this week’s quick post, I’m going to show you a tactic I use to ensure that you never lock yourself out while making changes to a Cisco router or switch configurations.
Wireless networking is now considered a must have in nearly all industries. It’s no surprise I get a lot of comments from clients who believe they are experiencing wireless trouble in some form or fashion. They aren’t sure if it’s related to wireless controller configuration, AP placement, coverage gaps, interference, or even client machine problems. Even though Wi-Fi is nearly as prevalent as indoor plumbing, it doesn’t mean it’s always deployed properly, is reliable enough, or fast enough to address our clients needs. When something is not quite right with WIFI performance, what do I do? I’ll tell you what I do! I suggest a wireless survey and wireless assessment. Surveys are the best tool a wireless engineer has available to assist them with visualizing an invisible medium like RF. Actively scanning the frequency ranges often used for Wi-Fi as the physical location is walked is the de-facto way to record concrete data on signal, strength, interference, and a whole range of other valuable information. It’s really the only way to understand exactly what’s happening between a laptop client and the access points that dot a location.
As an experienced Cisco network engineer, you have often saved yourself from being locked out of a router when you make a change with a “reload in x” command. This handy command reboots most Cisco devices (routers, switches, firewalls) in the x number of minutes that you had specified. Thus, if you made a change that killed your connection to it, then you just have to wait until the time expires and the device reboots back up with the last saved configuration, allowing you to reconnect and remove your palm from your forehead.
What is Zero Trust? Zero Trust is a framework and attitude towards IT security that centers on the idea that we in the IT field cannot trust anyone or any device on our network. Many systems administrators are well versed in this model. Every employee is assigned a domain joined laptop that is locked down via Group Policy. Those employees are tracked via a user identity using their AD profile that, through security groups, either allow or restrict access to various IT assets (servers, printers, wireless, and/or client VPN). Accounting is enabled to track what the users are accessing and used in the event of a malicious attack to see where the attack originated and who preformed the attack.
You are a great boss. You want to enable your team with the best tools to collaborate with so, in your infinite benevolence, you purchased a Cisco Webex Endpoint or maybe even a few of them. Your team is thrilled with the experience and ease of use.
Recently, I have been working to upgrade Cisco network devices, mainly routers and switches, for a client. A recent network audit identified fragmentation in the IOSes and also security advisories. As a result, all the routers and switches required upgrades and it was a good opportunity for the client to standardize the IOSes for the different type of network devices in the environment.
As promised, in this entry to our ISE blog series we are going to begin our adventure into Cisco TrustSec, or CTS for short. When I am approaching a new technology, I find it helpful to not only understand what it is, but also why it exists. So, in this post, we’re going to attempt to cover just that; what is Cisco TrustSec and why do I care?
If you haven’t heard, Cisco is redesigning their certification programs. Starting February 24, 2020 this new design will be in place. Let’s take a look at the upcoming changes.
