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:

You can set only one mask per port. When setting a mask, all existing

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.

Figure 11

shows the mask positions in the command.

‘< 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
