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 networkpros.org. For this blog, I utilize 2 x Dell S60s [FTOS 220.127.116.11 ]and 1x Dell S50N [FTOS 18.104.22.168]. Below is the network diagram for this lab. (more…)

Check out my latest blog on networkpros.org 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 22.214.171.124], and 2 x Dell S50Ns [FTOS 126.96.36.199].
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…)
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…)
