Testing procedures for network changes
Every network is growing, every network is becoming more complex due to all the requirements coming from the technology evolution or customer needs, e.g. building the more reliable network connections, application-based routing, etc. And all these facts are the triggers for all the changes we…
Troubleshooting basic discovery
One of the features that’s included in IP Fabric’s platform from the beginning of time is variability of network discovery inputs. First of all is Discovery Seed, which creates an entry point for discovery. Another functional feature is Filtering, which narrows down to what to…
Discovering First Hop Redundancy Protocol parameters
IP network gateway redundancy has become a very standard high availability solution. In IP Fabric’s platform it’s described as First Hop Redundancy Protocol (FHRP) feature that currently umbrellas HSRP, VRRP and GLBP protocol. I have prepared a little scenario in our virtual lab with a…
Export security policies from Juniper SRX
Juniper SRX is a wonderful firewall device with a lot of rich features. However sometimes the complexity of security policies may grow greatly with multiple embedded addresses or application objects, more virtual routing and forwarding instances, route leaks and so on. It can come to…
IP Fabric 2.2.5: Staying longer in network diagrams
This week we released IP Fabric version 2.2.5 which focuses on improvements of network diagram workflow, significantly improving the depth of information provided in the diagram tooltips, and improving readability of the End to End path diagrams. We’ve also added pseudo-STP links, or MAC edges,…
End to end network path analysis
If a user reports that a certain application is not working for them, especially after a migration or a change, how do you verify the connectivity? Finding a path in a complex network can be hard enough by itself, having to map active switching and…
IP Fabric 2.2.4
Today we’re announcing the release of IP Fabric 2.2.4. A network security oriented release, the new version enables you to troubleshoot the paths through firewall clusters, to have deeper insights into routing convergence and redundancy, or to prepare or verify migration changes to 802.1X among…
Spotting Single Points of Failure in a graph
Enterprise networks should never have Single Points of Failure (a.k.a SPOF) in their daily operation. SPOF in general is an element in a system which, if stopped, causes the whole system to stop. Single failure (or maintenance or misconfiguration) of any network device or link…
Chasing routes in the network
Have you ever tried to find out why the dynamic routing protocol in your network is not passing specific prefix as expected? And the situation had not improved even though ad-hoc static routes were created here and there? Networking protocols (while designed to be simple…
Announcing IP Fabric Platform v2.2
I’m pleased to announce the release of IP Fabric® Platform 2.2. Continuing our mission of delivering more capabilities into the hands of the network engineers, this major release exposes all predefined verification checks and enables to edit them or to define your own. Each technology…
