Table 42 Advanced performance monitoring commands (continued) Command Description perfSetPortEEMask perfShowAlpaCrc perfShowEEMonitor perfShowFilterMonitor perfShowPortEEMask Set the overall mask for EE monitors. Display the AL_PA CRC count by port or by AL_PA. Show user-defined EE monitors. Show filter-based monitors. Display the current EE mask of a port. NOTE: The command examples in this chapter use the slot/port syntax required by the Core Switch 2/64, SAN Director 2/128, and 4/256 SAN Director. For the 4/8 SAN Switch, 4/16 SAN Switch, SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, Brocade 4Gb SAN Switch for HP p-Class BladeSystem, and SAN Switch 4/32, use only the port number in the commands. Displaying and clearing the CRC error count You can use the perfShowAlpaCrc command to display the CRC error count for all AL_PA devices or for a single AL_PA on a specific active L_Port. The following is an example that displays the CRC error count for all AL_PA devices on a port: switch:admin> perfshowalpacrc 1/1 AL_PA CRC count 0xd9 0 The following is an example that displays the CRC error count for a single AL_PA device on a port: switch:admin> perfshowalpacrc 1/1, 0xd9 The CRC count at ALPA 0xd9 on port 1 is 0x000000000. The following is an example that clears the CRC error count: switch:admin> perfclralpacrc 1/1, 0xd9 CRC error count at AL_PA 0xd9 on port 1 is cleared. switch:admin> perfclralpacrc 1/1 No AL_PA value is specified. This will clear all AL_PA CRC counts on port 1. Do you want to continue? (yes, y, no, n): [no] y Please wait ... All alpa CRC counts are cleared on port 1. In Fabric OS 3.1.0, 4.1.0, and later versions, you can use the portStatsClear command clears AL_PA- based CRC error counters for all the ports in the same group. 200 Administering advanced performance monitoring
