The authors, who work for Cisco Systems, discuss virtual LANs, the hardware components that make multilayer switching work, quality of service on Catalyst 6500, the multicast features and protocols supported on the Catalyst switches, the data link layer, and the rapid spanning tree protocol
GbESM firmware provides a full set of Layer 2 features such as trunking, VLANs and Spanning Tree Protocol
LE-135B also delivers industry-leading resiliency with an advanced optimization of the Rapid Spanning Tree Protocol
Rapid Spanning Tree Protocol
: Mario Kozina, University of Zagreb; Steve Hemminger, OSDL mentor This assignment will help transition the Linux Ethernet Bridging project from a kernel implementation of the Spanning Tree Protocol
(STP) to a new user space implementation of the Protocol.
Engineers from The Tolly Group verified that the Xirrus Wi-Fi Arrays went through the default Spanning Tree Protocol
(STP) stages to re-establish network connectivity when broken links occurred during an FTP session.
In the event of an outage, data is automatically rerouted with minimal disruption and sub-second re-convergence, as opposed to traditional Spanning Tree Protocol
(STP) schemes which can take up to 60 seconds to re-converge.
The N2X layer-2 conformance test suites include the N5712A Spanning Tree Protocol
, N5713A Rapid Spanning Tree Protocol
, N5714A Multiple Spanning Tree Protocol
and N5715A Link Aggregation Control Protocol.
The focus of BT Exact's testing was Layer 2 Ethernet service provider solutions, concentrating on key carrier requirements for high availability, QOS scalability and security including SONET-like failure recovery mechanisms for 1 Gigabit Ethernet and 10GbE rings, sub-second protection with or without Spanning Tree Protocol
, hardware based QoS end-to end with Super Aggregated VLANs and network security against unauthorized access and Denial of Service (DoS) attacks.
