Resetting a port To reinitialize one or more ports and to discard any temporary changes that have been made to the administrative state or link speed, enter the reset port command. The following example reinitializes port 1: 8/20q FC Switch #> reset port 1 Configuring port threshold alarms The switch can monitor a set of port errors and generate alarms based on user-defined sample windows and thresholds. These port errors include the following: • Cyclic redundancy check (CRC) errors • Decode errors • ISL connection count • Device login errors • Device logout errors • Loss-of-signal errors You make changes to the port threshold alarms by modifying the switch configuration as described in "Modifying a switch configuration" on page 38. See Table 30 for a description of the port alarm threshold parameters. The switch will down a port if an alarm condition is not cleared within three consecutive sampling windows (by default, 30 seconds). Reset the port to bring it back online. An alarm is cleared when the threshold monitoring detects that the error rate has fallen below the falling trigger. 8/20q Fibre Channel Switch command line interface guide 55
