The license key is case-sensitive and must be entered exactly as given. Verify the license was successfully added by entering licenseShow on the command line: admin>...
  • Page 19 Installing Advanced Performance Monitoring Select the License Admin tab. Enter the license key in the License Key field exactly as provided by your switch supplier, and click Add (see Figure 2-2). The Advanced Performance Monitoring features are available as soon as the license is added.

  • Page 22: Al_Pa Performance Monitoring

    Using Advanced Performance Monitoring AL_PA Performance Monitoring AL_PA performance monitoring allows you to track and display the number of CRC errors that have occurred on frames sent to each AL_PA on a specific port. No monitor configuration is necessary for AL_PA performance monitoring. Displaying the CRC Error Count Use the perfShowAlpaCrc command to display the CRC error count for all AL_PA devices or a single AL_PA on a specific port.

  • Page 23: End-To-End Performance Monitoring

    Using Advanced Performance Monitoring End-to-end Performance Monitoring End-to-end performance monitoring counts the number of words and CRC errors in Fibre Channel frames for a specified Source ID (SID) and Destination ID (DID) pair. An end-to-end performance monitor counts: • the number of words in frames received at the port (RX_COUNT) •...

  • Page 24: Setting A Mask For End-To-End Monitors

    Using Advanced Performance Monitoring Monitor 0 counts the frames that have an SID of 0x051200 and a DID of 0x111eef. For monitor 0, RX_COUNT is the number of words from Host A to Dev B, CRC_COUNT is the number of frames from Host A to Dev B with CRC errors, and TX_COUNT is the number of words from Dev B to Host A.
  • Page 25 Using Advanced Performance Monitoring Use the perfSetPortEEMask to set a mask for end-to-end monitors. The command sets the mask for all end-to-end monitors of a port, so that you can selectively choose the Fibre Channel frames in which the number of words are to be counted. The perfSetPortEEMask command sets a mask for the Domain ID, Area ID, and AL_PA of the SIDs and DIDs for frames transmitted from and received by the port.

  • Page 26: Displaying The End-To-End Mask Of A Port

    Using Advanced Performance Monitoring Displaying the End-to-end Mask of a Port Use the perfShowPortEEMask command to display the current end-to-end mask of a port. The end-to-end mask has 12 fields, with each field having a value of on or off. Example.

    Using Advanced Performance Monitoring Example 1. The following command displays all of the end-to-end monitors on port 3 at an interval of once a second. (In this example, there are three monitors on port 3, numbered 0, 1, and 2.) sw1:admin>...

  • Page 28: Clearing End-To-End Monitor Counters

    Using Advanced Performance Monitoring Clearing End-to-End Monitor Counters To clear all of the end-to-end monitor counters on a port, use the perfSetPortEEMask command to reset all of the end-to-end monitor counters on that port. Note: The perfSetPortEEMask command also sets the end-to-end mask, so if you do not want to change the mask, you must re-specify the current mask settings.
