Chapter Using Advanced Performance Monitoring 3 This chapter provides the following information: • • • • • Overview on page 3-1 AL_PA Performance Monitoring on page 3-2 End-to-end Performance Monitoring on page 3-3 Filter-based Performance Monitoring on page 3-8 Saving and Restoring Monitor Configuration on page 3-12 Overview You can administer Advanced Performance Monitoring through telnet commands or through Web Tools (an optionally licensed product).
3 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. The port must be an active L_Port. Example 1.
Using Advanced Performance Monitoring 3 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.
3 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. Monitor 1 counts the frames that have an SID of 0x111eef and a DID of 0x051200.
Using Advanced Performance Monitoring 3 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. Figure 3-3 shows the mask positions in the command.
3 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. The following commands set an end-to-end mask on port 11 and display the mask: sw1:admin> perfSetPortEEMask 11, “00:00:ff”, “00:00:ff”, “00:00:ff”, “00:00:ff” The EE mask on port 11 is set and EE counters are reset.
Using Advanced Performance Monitoring 3 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> perfShowEEMonitor 3, 1 perfShowEEMonitor 3, 1: Tx/Rx are # of bytes and crc is # of crc errors 0 -----------crc Tx Rx ============ 0 0 0 0 53m 4.9m 0 53m 4.4m 0 53m 4.8m 0 53m 4.6m 0 53m 5.0m 0 52m 4.6m 1 -----------crc Tx Rx ============ 0 0 0 0 53m 4.9m 0 53m 4.
3 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. You can view the current mask settings using the perfShowPortEEMask command.

If the switch does not have enough resources to create a given filter, then other filters may have to be deleted to free up resources. Example 1. This command adds a filter-based monitor to count all FCP and IP frames received from domain 0x02 for port 2.
