Setting A Mask For End-To-End Monitors - HP StorageWorks MSA 2/8 - SAN Switch User Manual

Setting a Mask for End-to-end Monitors

End-to-end monitors count the number of words in Fibre Channel frames that
match a specific SID/DID pair. If you want to match only part of the SID or DID,
you can set a mask on the port to compare only certain parts of the SID or DID.
With no mask set, the frame must match the entire SID and DID to trigger the
monitor. By setting a mask, you can choose to have the frame match only one or
two of the three fields (Domain ID, Area ID, AL_PA) to trigger the monitor.
Note:
end-to-end monitors will be deleted.
The mask is specified 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).
Use the perfSetPortEEMask command to set a mask for end-to-end
monitors. This 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 you issue the
perfSetPortEEMask command, a message will display indicating the
existing End-to-end monitors will be deleted.
Example. The following message will be displayed when you issue the
perfSetPortEEMask command on a port with the existing end-to-end
monitors configured.
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.
Advanced Performance Monitoring Version 3.1.x/4.1.x User Guide
You can set only one mask per port. When setting a mask, all existing
'< n > EE monitors are currently programmed on this port.
Changing EE mask for this port will cause these EE monitors to
be deleted.
Do you want to continue? (yes, y, no, n): [no]
EE mask on port <port-number> is set and '<n>' EE monitors
were deleted
Figure 11 shows the mask positions in the command.
