Director 2/140 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.
