Lately we've been selling a lot of products from Cisco's Small Business Pro line. I wanted to take some time to write about my experiences with these products, specifically how they (and you!) interact with the corresponding software tools. This will be a two parter that

You might think it strange to start an article about firewall subscriptions by first talking about cars, but I promise this is perfectly relevant! If we went car shopping in the 1970s, today's consumer would notice the vast difference of safety features in vehicles compared to modern standards.

Packet Capture on a Remote Cisco Device Typically when I need to do a packet capture on a remote Cisco IOS/IOS-XE device, I use RSPAN to mirror that traffic someplace where a VM can receive the capture. This week I learned a trick that allows much more flexibility! ERSPAN

Portable Internet Service One of our healthcare clients needed a solution for running COVID-19 vaccination clinics in a parking lot or pavilion. They wanted to provide secure connectivity to electronic health records (EHRs) for a team of doctors, nurses and their support staff at any location. The challenge with these

This afternoon we received several reports all at once that the internet was down. Interestingly we were able to reach client locations, all SNMP monitoring looked healthy and no outages were present. We did however notice that bandwidth utilization had dropped to a trickle, so something was amiss! Eventually we

The Cisco ASA firewall can run as virtual host for multiple virtual ASA's known as contexts. We recently ran into an issue where a memory leak made one context inoperable. Rather than reload the entire ASA and take out the other contexts we wanted to only restart the

Here are a list of things to troubleshoot when a Ruckus AP is not registering to a Virtual SmartZone (VSZ) cloud controller. 1. Ensure that the public IP address of the site where the AP resides is permitted through the firewall protecting the VSZ. 2. Check that the AP has

In my first post on showing the client IP addresses through a Barracuda ADC load balancer, I showed how to get Direct Server Return to work for clients on the same network by adding loopback interfaces on the back-end servers. In this post I will discuss a problem when using

In order to see the client origination IP address on the real back-end servers when a Barracuda ADC load balancer is used there are two options. The first is to use layer 4 load balancing on the service type. The other option is to use a layer 7 proxy service

The Cisco 3750x switch does not support NetFlow natively, but the C3KX-SM-10G module has ASICs that support NetFlow. With the C3KX-SM-10G module, NetFlow can only be run on the 4 interfaces in the module -- this does not add NetFlow on the entire switch. It is however possible to capture

We had a problem with Barracuda's ADC load balancer and Outlook Web App for Exchange 2013. The user would get to the OWA login screen and login only to be brought back to the login screen again in an endless loop. We were using the "Instant SSL&

We've seen this happen twice recently with different customers so thought we should post our solution. We have seen where a Ubiquiti AP (NanoBeam & NanoStation) will power up via the power injector and the unit is reachable via wireless, but there is no link light on the
