Automating VLAN Configuration on Dell FTOS Switches via GVRP
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 … Continue reading

Distributed Core Network Architecture
There is no doubt you have probably heard by now the importance of supporting ‘east-west’ traffic flow in large data center networks. So why is this and what does it mean? And when Gartner claims that 80 percent of data … Continue reading

Configuring PVST+ on Cisco Switches
Per VLAN Spanning Tree Plus (PVST+) is a flavor of Spanning Tree Protocol (see prior blog, Default STP Behavior on Cisco Switches) which maintains a spanning tree instance for each VLAN in the network. This means certain VLAN trunks (using … Continue reading

Functionality of Layer 2 Switches/Bridges
Layer 2 switches and bridges switch frames on a network while layer 3 routers route packets between networks. I once heard a network engineer being asked if a network can be made faster if the network is optimized to use … Continue reading
