Changing the Root Password on Juniper JunOS Switches
In this short blog, I show how to easily change the root password on Juniper JunOS [JunOS 11.1R6.4] switches. It’s important to note, on a switch reset to default configuration, you can easily log into the switch with just the ‘root’ username without a password, however, you will not be able to ‘commit’ changes to the configuration until you set the root password; if you attempt to do so, you will get an error message stating “Missing mandatory statement: ‘root-authentication’error: configuration check-out failed: (missing statements)”. Below is a screenshot from a Juniper EX4200-48T displaying how to set/change the root password. Continue reading

Dell MXL/IOA with FC Flex IOM: Network and Infrastructure Convergence with NPIV Proxy Gateway
Dell FC Flex IO Module for Dell MXL/IOA Blade Switch
Very exciting news from Dell today as they announced the availability of the Dell FC Flex IOM module which transforms the Dell M1000e MXL/IOA blade switch into a NPIV Proxy Gateway (NPG). This allows the MXL/IOA to bridge between Ethernet and Fibre Channel allowing for network convergence with FCoE. Continue reading

LACP and Trunking Between Brocade FOS and Dell FTOS Switches
In this short lab I’ll demonstrate creating a LACP LAG and trunking between Brocade switches running FOS and Dell switches running FTOS. I utilize two Brocade 8000 switches [FOS 6.3], one Dell S60 switch [FTOS 8.3.3.8], and one Dell PowerEdge 2950 server with a QLogic QLE8242 CNA. Below is the network diagram for this lab.

AAA Login Authentication on Dell Switches Running FTOS
By default Dell switches running FTOS use local username/passwords for login authentication. This default behavior is assigned in the ‘default’ method list. To change the login authentication behavior, you can either modify the ‘default’ method list or create new method list(s). In FTOS, AAA (Authentication, Authorization, and Accounting) uses method lists to define the types of authentication and the sequence in which they are applied. Additionally, in FTOS, AAA provides the ability to have different security protocols/mechanisms used for different login methods. In this blog, I demonstrate how different login authentication security mechanisms can be used for different login methods. Continue reading

Network Virtualization with VMware NSX Dominates VMworld 2013
VMworld 2013 in San Francisco
I’ve been meaning to write this blog for some time now as VMworld 2013 ended in San Francisco in late August. However, as VMworld just eneded in Barcelona, Spain last week, I guess it’s still not too late. I have to say out of all the tech events/conferences I attend, VMworld 2013 is definitely one of the most informative and beneficial. With an agenda filled with back-to-back speaker sessions, hands-on-labs, discussions on the solutions exchange expo floor, networking opportunities, and informal after-hour events, VMworld has catapulted to a must-go-to event for those in the high tech industry of networking, systems, and Enterprise/Datacenter infrastructure.

OUYA: The ‘Open’ Video Game Console for Users and Developers
OUYA Game Console
Amazingly, OUYA, the open video game console platform raised $8,596,474 in funds on KickStarter. OUYA is based on the Android 4.0 operating system. The idea is to create a low cost console (currently $99) available for consumers that also allows developers to publish their Android games/apps to OUYA without requiring the purchase of an expensive SDK and paying licensing, retail, and publishing fees. Anyone is free to develop and publish games that can be easily downloaded and tried for free; if the user likes the app or game, he/she may purchase the full version. It’s actually quite innovative in the sense that the traditional closed living room gaming experience is now open to any developer without the traditional costs associated with developing games for known platforms like Nintendo Wii, Microsoft Xbox, or Sony Playstation.

Dell Networking Extends Multipathing Capabilities with VLT Routing
Dell Networking recently released enhancements to their VLT multipathing technology in FTOS 9.2 now available on S4810, S4820T, and Z9000. For a quick primer on Dell’s VLT technology read my prior blog post here. The most noticeable enhancement is the support of layer 3 routing protocols over VLT. Additional enhancements include the ability of VLT peers to synchronize ARP entries learned from non-VLT interfaces, support for IPv6, and the ability to synchronize multicast routing tables between peer VLT ports. In this blog, I use 4 x Dell S4810s [FTOS 9.2] and 1 x Dell S60 (for a management switch) [FTOS 8.3.3.9] to demonstrate routed VLT.
