Setting a mask for an end-to-end monitor
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. By default, 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, and AL_PA) to trigger the monitor.
You specify the masks 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
.
NOTE: Only one mask per port can be set. When you set a mask, all existing end-to-end monitors are
deleted.
End-to-end masks are not supported on the following:
• HP StorageWorks DC SAN Backbone Director
• HP StorageWorks DC04 SAN Director Switch
• HP StorageWorks 8/8 and 8/24 SAN Switches
• HP StorageWorks 8/40 SAN Switch
• HP StorageWorks 8/80 SAN Switch.
On HP StorageWorks SAN Director 48 Port 4Gb FC 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 HP StorageWorks SAN Director 48 Port 4Gb FC blades.
1. Connect to the switch and log in as admin.
2. Enter the
perfSetPortEEMask
command.
perfsetporteemask [slotnumber/]portnumber "TxSIDMsk" "TxDIDMsk"
"RxSIDMsk" "RxDIDMsk"
where:
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 entered, a message is
displayed similar to the following example:
switch:admin> perfsetporteemask 1/2, "00:ff:ff"
Changing EE mask for this port will cause ALL EE monitors on this port to
be deleted.
Continue? (yes, y, no, n): [no] y
The EE mask on port 2 is set and EE monitors on this port are 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 73 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
slotnumber
For bladed systems only, specifies the slot number of the port on which the mask is to
be added. For all other switches, this operand is not required.
portnumber
Specifies the port number
TxSIDMsk
Specifies the transmitting source ID mask
TxDIDMsk
Specifies the transmitting destination ID mask
RxSIDMsk
Specifies the receiving source ID mask
RxDIDMsk
Specifies the receiving destination ID mask
