No Switch in Dhub:
Sample Configurations for
Cisco Catalyst 4500 Series Switches

This appendix presents example configurations, using VLANs, for the following redundancy scenarios for no-switch-in-Dhub scenarios.

The following configurations are presented:

• Single VLAN

• Split VLAN

• Multiple VLANs

Single VLAN
