Setting a mask for an end-to-end monitor You can specify a mask using the perfSetPortEEMask command in the form dd:aa:pp, where dd is the Domain ID mask, aa is the area ID mask, and pp is the AL_PA mask. The values for dd, aa, and pp are either ff (the field must match) or 00 (the field is ignored). The default EE mask value is ff:ff:ff. The perfSetPortEEMask command sets the mask for all end-to-end monitors of a port. If any end-to-end monitors are programmed on a port when the perfSetPortEEMask command is issued, then a message displays similar to the following example: switch:admin> perfsetporteemask 1/2, "00:ff:ff" EE monitors are currently programmed on this port. Changing EE mask for this port will cause ALL EE monitors on this port to be deleted. Do you want to continue? (yes, y, no, n): [no] y EE mask on port is set and EE monitors were deletedThe 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 37 shows the mask positions in the command. A mask ("ff") is set on slot 1, port 2 to compare the AL_PA fields on the SID and DID in all frames (transmitted and received) on port 2. The frame SID and DID must match only the AL_PA portion of the specified SID-DID pair. Each port can have only one EE mask. The mask is applied to all end-to-end monitors on the port. Individual masks for each monitor on the port cannot be specified. Transmitted from port Received by port SID mask DID mask SID mask DID mask perfsetporteemask 1/2, "00:ff:ff" "00:ff:ff" "00:ff:ff" "00:ff:ff" AL_PA mask Area ID mask Domain ID mask Figure 37 Mask positions for end-to-end monitors On FC4-48 port blades, the upper 32 ports can be addressed only when the area ID and the AL_PA are used together. For usability concerns, the area ID and the AL_PA cannot be masked separately for any ports on FC4-48 port blades. End-to-end masks are not supported on the DC Director. Deleting end-to-end monitors To delete an end-to-end monitor: 1. Enter the perfShowEEMonitor command to list the valid monitor numbers for a port. 2. Enter the perfDelEEMonitor command to delete a specific monitor. If you do not specify which monitor number to delete, you are asked if you want to delete all entries. The following example displays the end-to-end monitors on port 0 using the perfShowEEMonitor command (the monitor numbers are listed in the KEY column) and deletes monitor number 2 on port 0 using the perfDelEEMonitor command: switch:admin> perfshoweemonitor 0 There are 4 end-to-end monitor(s) defined on port 0.
