5.2 Layer 2
This section refers to basic Layer 2 configuration for all Top-of-Rack switches referred to in
this publication. Any differences between models regarding the availability of certain software
features or command syntax are highlighted.
All the configurations presented in this chapter were implemented by using IBM Networking
Operating System V6.8 (previously know as BLADEOS) software installed in the reference
architecture switches. Configuration steps and examples are presented for each command
on selected equipment. We assume that the template can be easily replicated for the
remaining ports and equipment according to the reference architecture. For the architecture
planning details, VLAN numbers and assignment, trunks, and so on, 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 5.5, “More information” on page 238.
The following topics are described in this section:
򐂰 VLANs
򐂰 Ports and trunking
򐂰 Spanning Tree Protocol
򐂰 Quality of Service
5.2.1 VLANs
For information about the VLAN-related configuration that is applied to the reference
architecture switches, see Chapter 3, “Reference architectures” on page 107.
