Overview of this book

Cisco Unified Computer System (UCS) is a powerful solution for modern data centers and is responsible for increasing efficiency and reducing costs. This hands-on guide will take you through deployment in Cisco UCS. Using real-world examples of configuring and deploying Cisco UCS components, we’ll prepare you for the practical deployments of Cisco UCS data center solutions. If you want to develop and enhance your hands-on skills with Cisco UCS solutions, this book is certainly for you. We start by showing you the Cisco UCS equipment options then introduce Cisco UCS Emulator so you can learn and practice deploying Cisco UCS components. We’ll also introduce you to all the areas of UCS solutions through practical configuration examples. Moving on, you’ll explore the Cisco UCS Manager, which is the centralized management interface for Cisco UCS. Once you get to know UCS Manager, you’ll dive deeper into configuring LAN, SAN, identity pools, resource pools, and service profiles for the servers. You’ll also get hands-on with administration topics including backup, restore, user’s roles, and high availability cluster configuration. Finally, you will learn about virtualized networking, third-party integration tools, and testing failure scenarios. By the end of this book, you’ll know everything you need to know to rapidly grow Cisco UCS deployments in the real world.

Preface

Configuring VLANs


VLAN configuration on Fabric Interconnects can be done either through LAN Uplink Manager or through the LAN tab in the navigation pane. Typically, both Fabric Interconnects have the same VLAN configuration, which is called global VLAN configuration. It is possible to configure VLANs that are available on only one of the two Fabric Interconnects which is called FI-specific VLAN configuration. It is also possible to configure a same VLAN differently on both Fabric Interconnects. Fabric Interconnects also support the creation of private VLANs.

The default VLAN is VLAN 1, which cannot be deleted and is available on both FIs. VLAN 1 is also the native VLAN. VLANs can be configured in the range of 1-3967 and 4049-4093. The 3968-4048 and 4094 VLAN IDs are reserved for system use on FIs and cannot be configured.

As the uplink ports on Fabric Interconnects are always trunk ports, UCS Manager automatically manages the allowed VLANs on FI uplink ports whenever a VLAN is created, deleted...
