STP Fast Mode for Overcoming Server Access Failures. If an end node
is configured to automatically access a server, the duration of the STP startup
sequence can result in a “server access failure”. On ports where this is a
problem, configuring STP Fast Mode can eliminate the failure. For more
information, see “STP Fast Mode” on page 9-109. Also, for more information
on STP, see “How STP Operates” on page 9-108.
In the factory default configuration, STP is off. If a redundant link (loop) exists
between nodes in your network, you should enable Spanning Tree.
N o t e
STP retains its current parameter settings when disabled. Thus, if you
disable STP, then later re-enable it, the parameter settings will be the same
as before STP was disabled.
C a u t i o n
Because the switch automatically gives faster links a higher priority, the
default STP parameter settings are usually adequate for spanning tree
operation. Also because incorrect STP settings can adversely affect network
performance, you should not make changes unless you have a strong under-
standing of how STP operates. For more on STP, see the IEEE 802.1D standard.
