Chapter 13 Network Configuration Problems

Many reported problems on a booted switch will ultimately be traced back to user errors in the layer 2 or layer 3 switch configuration. In some cases, symptoms from an improperly configured switch can masquerade as potential hardware problems.

Interface Overview

On startup OpenArchitect creates interfaces for all Ethernet ports on the Ethernet Switch Blade. The three types of interfaces within the OpenArchitect environment are:

•zhp - Host Port: A zhp interface is associated with one VLAN (Virtual Local Area Network). zhps can contain one or more physical interfaces (zres) to create a private network that does not let traffic cross interfaces outside of the VLAN.

•zre - Raw Ethernet: An interface that represents a physical port on the OpenArchitect switch.

•zrl – Trunk of Ports (Link Aggregation)

•eth - Each switch, fabric and base, in a Ethernet Switch Blade Series unit has Out-of- Band (OOB) Ethernet port on the front panel. These are an alternative maintenance port supplying Ethernet connectivity instead of serial connectivity and are connected only when performing switch maintenance activities.

Physical Interfaces

The tables below provides a translation guide for mapping the zre ports to the termination point. Table 13.1 details the zre interface to the slot in the backplane that it terminates. Table 13.2 lists all other Ethernet Switch Blade interfaces including management, and egress ports.
