I was upgrading a Catalyst 3850 48 port switch from version 03.07.01E to version 16.12.07. I’ve done this upgrade quite a few times. Followed the Cisco upgrade procedures that you find online when you download your software file. I always have them open, or the command needed to start the upgrade process. Console access showed me that my switch after my reload ended up in ROMMON mode.

In the first entry of this series, we looked at the high-level mechanics involved in using AnyConnect with the ISE Posture module to perform endpoint host inspection (posture) when connecting to an AnyConnect VPN head-end (ASA/FTD). In the second entry of this series, we narrowly focused on getting the ISE posture module provisioned. In the third entry, we took stock of all the available posture...

Whether you’re migrating from On Prem Call Manager to WebEx Calling, Spark to WebEx Calling or just have some old phones you want to add to your WebEx Calling Deployment; you will need to convert your phones from their Enterprise Firmware to the cloud supported MPP firmware.

Cisco Meraki recently introduced the MG series Cellular Gateways to be a reliable solution as a backup internet uplink. In the event that the primary internet uplink goes down, the MG gateway will provide high availability for internet connectivity via wireless WAN connectivity using a cellular network. The MG Series also simplifies configuration and management using Meraki’s dashboard.

You read that right! At Cisco Live this year they introduced the ability to add Catalyst switches to the Meraki dashboard. Finally a use for the unused DNA licenses! The switches are monitored in read-only mode, so you still need to manage the switches the old fashioned way, however Meraki's traffic analysis and troubleshooting tools are available for use. This is great for Catalyst owners who do...

Hoteling is bringing Extension Mobility (Call Manager realm) to the cloud-based WebEx Calling solution. It allows a user to pick any phone and login to it using their extension and voicemail pin number.

The topic of backing up is not always linear. Backing up a system can sometimes be confusing topic among System and Network Engineers. There are always multiple ways to back up and restore, but is it the recommended for the system? For example, experience has shown me that enabling virtual machine snapshots to systems like ISE can present itself with larger operational issues like sporadic...

I recently completed my Ekahau Design training and certification. During the first day of class the instructor went over wireless fundamentals. Now as an experienced wireless engineer most of the topics were ideas that I had already known, however there were a few idea's that changed the way I understand wireless for the better. Lets walk though each of these idea's together!
