CAUTION: Only one mask per port can be set. When you set a mask, all existing EE monitors are deleted. 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 command sets the mask for all EE monitors of a port. If any EE monitors are programmed on a port when the perfSetPortEeMask command is issued, a message is displayed as shown in the following example: switch:admin> perfsetporteemask 1/2, "00:00: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 deleted 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 12 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 EE monitors on the port. Individual masks for each monitor on the port cannot be specified.
