Chapter 13
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:
•
•
•
•
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.

Network Configuration Problems
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.
