ISL Trunking for Ethernet Fabric Networks

Extreme VCS fabrics and all VDX switches utilize hardware-based ISL Trunking to provide high-performance, high-throughput Inter-Switch Links, to simplify interconnect configuration, to provide automatic link failover with no interruption of traffic on unaffected links, and to provide plug-and-play fabric scalability. With ISL Trunking you:

• Reduce the number of lines on a logical topology map
• Improve traffic and capacity provisioning to keep systems and applications running at full speed
• Simplify network design, capacity planning, and fabric administration
• Have fewer management touch points, since trunks are self-provisioning and auto-forking

In summary, ISL Trunking delivers:

• Optimal VCS fabric performance and throughput while enabling simplified network design
• Simplified management of VCS fabrics by reducing the number of logical entities to manage
• Improved fabric resiliency if individual ISL links fail
