10 Configuring Dual-Home
Links
Dual-Home Link (DHL) is a high availability feature that provides fast failover between core and edge
switches without implementing Spanning Tree. The OmniSwitch provides the following method for
implementing a DHL solution:
DHL Active-Active—an edge technology that splits a number of VLANs between two active links. The
forwarding status of each VLAN is modified by DHL to prevent network loops and maintain connectivity
to the core when one of the links fails. This solution does not require link aggregation.
In This Chapter
This chapter describes the basic components of DHL solutions and how to configure them through the
Command Line Interface (CLI). CLI commands are used in the configuration examples; for more details
