Automating VLAN Configuration on Dell FTOS Switches via GVRP

Saturday, February 22nd, 2014

GARP VLAN Registration Protocol (GVRP) is a standards-based protocol defined in the IEEE 802.1Q specification that provides for automatic VLAN configuration on switches. The Generic Attribute Registration Protocol (GARP) is used by switches supporting GVRP to register/de-register attribute values such as VLAN IDs between switches within the network. GVRP is the standards-based equivalent to Cisco’s Virtual Trunk Protocol (VTP). To read more about Cisco VTP, read my prior blog at For this blog, I utilize 2 x Dell S60s [FTOS ]and 1x Dell S50N [FTOS]. Below is the network diagram for this lab. (more…)


Redistribution of EIGRP and OSPF in a Hybrid Cisco/Dell Network

Sunday, February 16th, 2014

Check out my latest blog on where I demonstrate redistributing EIGRP routes into OSPF and redistributing OSPF routes into EIGRP in a mixed Cisco IOS and Dell FTOS environment. Of course only the Cisco switches are running EIGRP and all Dell switches are running OSPF. A Cisco Catalyst 6509 switch chassis is running both EIGRP and OSPF, and this is where the redistribution occurs. For this lab I use 1 x Cisco Catalyst 6509 [IOS 12.2(18)SXD7b], 1 x Cisco 7204VXR router [IOS 12.2(11)T9], 2 X Dell S60s [FTOS], and 2 x Dell S50Ns [FTOS].


Dell MXL and FC Flex IOM: Enabling Network Convergence via FCoE [Video]

Saturday, February 8th, 2014

As you know from my prior blog, blog, the Dell FC Flex IOM adds 4 x FC ports (8 x FC ports with 2 modules) to the Dell MXL/IOA blade switch and transforms it into a NPIV Proxy Gateway (NPG) allowing for the bridging of FCoE and Fibre Channel at the switch blade level. Check-out the video here on YouTube (also embedded below) or on the Dell MXL wiki page (second video on page) that steps through the details and ease of deployment of this solution. (more…)


Writing Useful Batch Scripts for Windows

Sunday, February 2nd, 2014

An often overlooked utility in Windows is the use of batch scripts.A batch script is nothing but a text file with the ‘.bat’ extension containing a series of commands to be executed by the Windows command interpreter. Along with calling programs from the command prompt, branching and looping logic is also possible. In this blog, I demonstrate some useful batch script functionality; I use Windows 7 as the operating system. (more…)
