64 Installation Guide (AA-RSNGD-TE, July 2004)

Overview

24 Director 2/64 Installation Guide

— Build fabric protocol error—A protocol error is detected during the

process of forming the fabric.

— No principal switch—No director in the fabric is capable of becoming

the principal switch.

— No response from attached switch—After a fabric is created, each

director in the fabric periodically verifies operation of all attached

switches and directors. An ISL segments if a switch or director does not

respond to a verification request.

— ELP retransmission failure timeout—A director that exhibits a

hardware failure or connectivity problem cannot transmit or receive Class

F frames. The director did not receive a response to multiple exchange

link protocol (ELP) frames, did not receive a fabric login (FLOGI) frame,

and cannot join an operational fabric.

Hardware Components

The Director provides a modular design that enables quick removal and

replacement of FRUs. The following sections define Director 2/64 main
