6.4 Layer 2 implementation
This section refers to basic Layer 2 configuration for the Virtual Fabric 10Gb Switch Module.
All the configurations presented in this section are implemented by using IBM Networking OS
V6.8 installed in the reference architecture switches. Configuration steps and examples are
presented for each command on selected equipment. It is assumed that the template can be
easily replicated for the remaining ports and equipment according to the reference
architecture. For the architecture planning details, such as VLAN numbers and assignment,
and trunks, see Chapter 3, “Reference architectures” on page 107.
Not all the Layer 2 functions available in IBM Networking OS V6.8 are covered in this section.
For an extensive list of features and configuration guidelines, see the documentation links
listed in 6.7, “More information” on page 284.
The following topics are described in this section:
򐂰 VLANs
򐂰 Ports and trunking
򐂰 Spanning Tree Protocol (STP)
򐂰 Quality of Service (QoS)
