In addition, IRF technology enables network-based In-Service-Software-Upgrades (ISSS) to ensure network and business continuity by extending the switch fabric control plane across multiple active switches, providing a rapid, sub 50-millisecond recovery in the event of network disruption verses up to several seconds for traditional Spanning Tree Protocol
(STP)-based network designs.
Designed for self study but also useful as a reference when completed, this product-based guide explains elements of the associated exam which include modular network design, switch operation and configuration, switch port configuration, VLANs and the VLAN Trunking Protocol, aggregated switch links, Spanning Tree Protocol
configurations as well as its security and advanced features, multilayer switching, router redundancy and load balancing, concepts of load balance and quality of services, DifferServ quality of service configurations, Internet telephony on Catalyst switches, securing switch access and VLANs.
Topics include single-areas OSPF, EIGRP and troubleshooting routing protocols, switching concepts, LAN design and switches, catalyst switch configurations, spanning tree protocol
, virtual LANs, and VLAN trunking protocol.
The author explains the multilayer switching approach to campus networking with Catalyst switches, and explores the role of VLANs, spanning tree protocol
, redundancy, quality of service, monitoring, and security.
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
LE-135B also delivers industry-leading resiliency with an advanced optimization of the Rapid Spanning Tree Protocol
