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

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. Continue reading
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

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.

Cisco’s vPC technology is similar to Dell’s VLT; it enables an access/leaf switch or server to have single LAG connecting up to two separate switches. This allows for an non-blocking, multipathing scenario. You can read more about Dell’s VLT technology and its advantages on my prior blog, Dell Force10 – Layer 2 Multipathing via Virtual Link Trunking (VLT) In this blog, I will configure Cisco vPC between two Cisco Nexus 5548UP switches [NX-OS 5.1(3)N2(1)] down to a third ToR Cisco Nexus 5548UP switch [NX-OS 5.1(3)N2(1)]. I will then replace the third Cisco Nexus 5548UP switch at ToR with a Dell S4810 switch [FTOS 9.0]. Continue reading
Check out the latest Dell S5000 converged switch video which demonstrates FCoE with the Dell S5000 converged switch and the Dell PowerEdge M1000e chassis w/ MXL blade switch. The Dell S5000 switch is configured in NPIV Proxy Gateway mode and the Dell MXL blade switch is configured for FCoE Transit. Additionally, the FCoE and LAN connectivity is tested by sending LAN and SAN traffic from the Dell PowerEdge M620 blade server. Multipathing over dual fabrics is also demonstrated by logging into the Fibre Channel switches and observing the FC traffic passing over both fabrics. Just see the second video posted on the following page on Dell’s website here, Dell Tech Center YouTube channel here, or just see the video directly below. Continue reading
