Resetting a port
Enter the Reset Port command to reinitialize one or more ports and to discard any temporary changes
that have been made to the administrative state or link speed. The following example reinitializes port 0:
McDATA4GbSAN #> reset port 0
See the ”Reset command” on page 132.
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
• Login errors
• Logout errors
• Loss-of-signal errors
You make changes to the port threshold alarms by modifying the switch configuration as described in
”Modify a switch configuration” on page 35. Refer to Table 24 for a description of the port alarm
threshold parameters.
The switch will bring down a port if an alarm condition is not cleared within three consecutive sampling
windows (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.
