2 perfAddEEMonitor perfAddEEMonitor Adds an end-to-end monitor to a port. SYNOPSIS perfaddeemonitor [slot/]port SourceID DestID [-force] DESCRIPTION NOTES Use this command to add an end-to-end performance monitor to a port. The performance monitor counts the number of words received, number of words transmitted, and number of CRC errors detected using either of the following conditions: • For frames received at the port, the frame SID is the same as SourceID and frame DID is the same as DestID; both RX_COUNT and CRC_COUNT are updated accordingly. • For frames transmitted from the port, the frame DID is the same as SourceID and frame SID is the same as DestID; both TX_COUNT and CRC_COUNT are updated accordingly. To monitor traffic from host A to device B, add a monitor on port 2, specifying 0x050200 as the SID and 0x010100 as the DID. The RX count equals the number of words from host A to device B, whereas the TX count equals the number of words from device B to host A. The CRC count equals the total number of CRC errors for both directions. Adding a monitor on port 1, specifying 0x010100 as SID and 0X050200 as the DID has a similar effect, except the RX and TX counts are interchanged. To monitor traffic between one Initiator host and one target storage device connected to an Encryption Switch, you must add two monitors because of the manner in which the real initiators or targets transfer data to VIs and VTs. The first monitor would be added between the initiator SID and the virtual initiator DID, and the second monitor would be set up between virtual target SID and the target DID. Refer to the Examples section for details. Identical monitors cannot be added to the same port. Two monitors are considered identical if they have the same SID and DID values after applying the end-to-end mask. Execution of this command displays a monitor number, which can be used to manipulate performance monitors. Because of a hardware limitation on Brocade devices, the following types of monitors cannot coexist on the same ASIC chip: • If an end-to-end monitor is installed on a port in a given ASIC, you cannot install an ingress or egress Top Talker monitor on another port on the same ASIC. • If an ingress Top Talker monitor is installed on a port in a given ASIC, you cannot install an egress Top Talker monitor or an end-to-end monitor on another port of the same ASIC. • If an egress Top Talker monitor is installed on a port in a given ASIC, you cannot install an ingress Top Talker monitor or an end-to-end monitor on another port of the same ASIC. You can use the -force option to override these limitations and install incompatible monitors on ports of the same ASIC. However, if you choose to do so, be aware that the statistics will not be accurate. This command requires an Advanced Performance Monitoring license. This command is not supported on virtual FC ports (VE/VEX_Port), EX_Port, M (Mirror) ports, and GbE ports. On 8Gb (Condor 2-based) platforms, End-to-End monitors are supported only on F_Ports. On 16Gb (Condor 3-based) platforms, End-to-End monitor are supported on both F_Ports and E_Ports. When installing an end-to-end monitor on an E_Port, be sure to install the SID and DID in the ingress direction. End-to-end monitors are non-persistent and will be removed when you reboot the system or disable the port. To make the monitors persistent, issue the perfCfgSave command before you perform operations that causes the port to go offline. Issue the perfCfgRestore command after the port comes back up. 592 Fabric OS Command Reference 53-1002746-01
