Force10 S4810 VLT – Quick Configuration sample

. I have already given a non-technical synopsis on VLT in one of my previous posts here As mentioned, VLT Is a Dual Active Control Plane implementation, of a Multi System LAG. Cisco vPC is a similar technology. VLT is beneficial in environments where the downstream devices like servers or access/distribution switches need to build … Continue reading

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. An important point to remember in comparison of these three methods is that in vPC, the control planes of the peer switches are separate, unlike Stacking/VSS where all switches are … Continue reading

Setting an Uplink VCP on a Standalone Switch – Juniper EX4200

You can set an uplink VCP on a standalone switch. You must set an uplink port on the standalone switch as a VCP prior to physically interconnecting the switch with the existing Virtual Chassis configuration. Otherwise, the master cannot detect that the switch is a member of the Virtual Chassis configuration. To set one uplink … Continue reading

Juniper EX 4500 – Virtual Chassis & Interconnect

  EX4500 switches ship with either the intraconnect module or the Virtual Chassis module preinstalled. Both modules are installed horizontally on the rear of chassis. However, only one of the modules can be installed at a given time. The intraconnect module helps the switch achieve line rate on all its ports. The VC module has … Continue reading

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 of MLAG) model, in the different layers of the switching infrastructure. This post draws a comparison between Stacking and Standalone models. A different post draws the comparison between stacking and … Continue reading
