Let’s say you have a Dell PowerEdge M1000e chassis populated with Dell blade servers with CNAs. Let’s also assume you enable FCoE on the CNA and utilize it for LAN and SAN traffic.

What if you were to use the CNA port’s WWPN (World Wide Port Name) within your zoning configuration on a backend Fibre Channel switch? What would occur if the CNA adapter went bad and needed to be replaced? Well, you would have to manually change all configurations that reference the LAN MAC Address or FC WWPN. In this case, the zoning configuration would have to be updated. This is where Dell’s M1000e FlexAddressing technology can help. (more…)

LACP and Trunking Between Juniper JunOS and Dell FTOS Switches

Sunday, January 26th, 2014

In this blog I demonstrate how to configure a LACP LAG and 8021.Q trunking between Juniper JunOS switches and Dell FTOS switches. I will utilize 2 x Juniper EX4200-48T switches [JunOS 11.1R6.4] and a Dell S60 switch [FTOS 8.3.3.9]. Below is the network diagram for this lab. (more…)

Changing the Root Password on Juniper JunOS Switches

Sunday, January 26th, 2014

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. (more…)

Dell FC Flex IO Module for Dell MXL/IOA Blade Switch

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. (more…)

LACP and Trunking Between Brocade FOS and Dell FTOS Switches

Saturday, January 18th, 2014

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. (more…)

Default Port and VLAN Configuration/Behavior on Cisco IOS switches

Wednesday, January 1st, 2014

In this short lab, I use two Cisco Catalyst 3550 switches [IOS 12.2(44)SE6] to demonstrate the default port and VLAN behavior on a Cisco switch running IOS. Below is the network diagram for this lab. (more…)
