Dell EMC Networking + Big Switch Cloud Fabric : Firewall Service Insertion – Part 2
Continued from Part 1. VLANs/Gateways terminate on Switch. Single Edge VLAN between FW and BCF. Default/static route in each direction. For Comparison with traditional NOS,
Big Switch – Cloud Fabric: Deployment Options | Dell EMC Networking
Before talking about the components, some quick observations on the Cloud Fabric Deployment considerations. Often, BSN Cloud Fabric may be the first SDN venture for
Big Switch – Cloud Fabric: Physical Vs. Logical Topology | Dell EMC Networking
Big Switch’s Big Cloud fabric decouples the logical topology from the physical. The constructs are familiar – the implementation nuances are easily assimilated, once adequate
Leaf & Spine: L3 Vs. L2 (VLT)
A short & sharp comparison of Layer 3/ECMP Leaf & Spine vs. Layer 2 Multi-chassis Link Aggregation, e.g. Dell EMC VLT (Virtual Link Trunking) Topologies.
Leaf & Spine Vs. Spline (+ Dell EMC Networking S6100-ON)
In essence, Spline collapses the Leaf & Spine functions – much like the Functions of Core & Aggregation Layers in a traditional 3-tier topology, would
SDN Design Principles for Networks
Software Defined and Open Networking as a topic of interest, crops up in close to 80% of all Data Center opportunities I engage in. Even
VLT, Peer Routing and Routed VLT – Dell Networking
Core Config Options: First Hop/Gateway Redundancy: VRRP: Same Switch hosts VRRP and STP Master-ship for deterministic forwarding @ L2/L3 and eliminate suboptimal forwarding path. In
Force10 S4810 – Stacking Vs. VLT
. Cisco offers three solutions for eliminating STP. These comprise the stacking feature on 3750/2950 models, VSS on 6500s, and vPC on Nexus 5k/7k platforms.
Powerconnect SFP/Fiber connectivity – Options, Requirements and Troubleshooting
Basic requirements for fiber connections on PowerConnect switches: MMF optical cables, LC connectors, and SFP transceivers. 1) Optical Cables : Single Mode Vs Multi Mode Single Mode
Powerconnect – Stacked Vs. Standalone Configuration
. A fairly common design choice to be faced with during deployments, is whether to use Stacking, Standalone, or vPC/VLT (a dual control plane implementation
