Timeout Values
The switch timeout values determine the timeout values for all ports on the switch.
Table 4-5 describes the switch timeout parameters. The timeout values must be
the same for all switches in the fabric.
NOTE: Mismatched timeout values will disrupt the fabric. These should not be
changed unless absolutely necessary. Therefore, the switch must be
offline to change these values. Use the Switch Properties dialog to take
the switch offline.
