Dynamic ISL (DISL)

Introduction

A Cisco protocol, Dynamic Inter-Switch Link Protocol (DISL) simplifies the creation of an ISL trunk from two interconnected Fast Ethernet devices. Fast EtherChannel technology enables aggregation of two full-duplex Fast Ethernet links for high-capacity backbone connections. DISL minimizes VLAN trunk configuration procedures because only one end of a link needs to be configured as a trunk.
