What Is Network Collective?
In short, Network Collective is a bi-weekly video roundtable where data networking engineers talk about industry trends, challenging projects, and what it takes to do network engineering day-to-day. For a more thorough description of what were up to, please take a minute to watch the video above.

Extreme-ly Interesting Times In Networking
If you’re a fan of Extreme Networks, the last few months have been pretty exciting for you. Just yesterday, it was announced that Extreme is buying the data center networking business of Brocade for $55 million once the Broadcom acquisition happens. Combined with the $100 million acquisition of Avaya’s campus networking portfolio on March 7th and the purchase of Zebra Wireless (nee Motorola) last September, Extreme is pushing itself into the market as a major player. How is that going to impact the landscape?
Building A Better Business
Extreme has been a player in the wireless space for a while. Their acquisition of Enterasys helped vault them into the mix with other big wireless players. Now, the rounding out of the portfolio helps them complete across the board. They aren’t just limited to playing with stadium wifi and campus technologies now. The campus networking story that was brought in through Avaya was a must to help them compete with Aruba, A Hewlett Packard Enterprise Company. Aruba owns the assets of HPE’s campus networking business and has been leveraging them effectively.
The data center play was an interesting one to say the least. I’ve mused recently that Brocade’s data center business Continue reading

Network Device Authentication with Ansible 2.3
In a recent post, Coming Soon: Networking Features in Ansible 2.3, one of the key features to be introduced is a new connection framework. This new connection framework supports persistent SSH connections for modules that communicate with network devices via two methods:
1) the tried and true CLI method
2) the newly included NETCONF method
With the new connection framework, the network modules are currently undergoing a transformation with regards to how credentials are supplied. In Ansible versions 2.0 to 2.2, network modules support providing connection credentials as top-level arguments in the module.
If you want to build a task using the ios_command Ansible module the credentials used to authenticate to the device could be provided as top level arguments. The following example demonstrates the simplest form of passing credentials to modules in order to authenticate to the remote device:
ios_command:
commands: show version
host: “{{ inventory_hostname }}”
username: cisco
password: cisco
In some cases, such as with configuration modules, additional authentication details are required. In order to enter configuration mode, the Playbook tasks must first enter “enable” mode and, in some cases, supply an enable-mode password. Notice the additional two arguments (authorize and auth_pass) added to Continue reading
