Hi,
First i would recommend you do an snmpwalk against the SAN switch to a file
, after you grep parts of the OID sent with the trap. You should be able to
see what OID is used Port, Port Index , PortName , which you need after in
a script useing snmpget .
I wrote a script as automatic action on the Port Status Change Trap and
gave "$*" as a parameter, in the script you have to extract the OID and do
an snmpget about the Port, PortName whatever ...
or, maybe in your switch the last from the OID-1 is your port . like .
16.0.0.96.105.128.109.226.0.0.0.0.0.0.0.0.21 (Integer): 3
would means port 21-1 = Port 20 , not very nice but might work as well.
And the status (up/down) you have as a value in the trap anyway.. ( like 3
= Up , ...-> check FCMGMT mib )
If you have a cisco-mds then you might only need the Index sent with the
trap , all other information i found in the starndard interface mib.
hope this might help,

Hi,
The answer is unfortunately nowhere.
The fiber channel management traps are useless, I used to configure MLM to
check the active ports and issue specific traps when needed, and of course
to block all incoming fcmgmt traps.
This can also be done through a script or in Netview.
Hope this helps,
Best regards

INformation
in traps
Can any one tell me how I get the port number from this entry.
The mib definition is
connUnitPortStatusChange TRAP-TYPE
ENTERPRISE fcmgmt
VARIABLES { connUnitPortStatus, connUnitPortState }
DESCRIPTION
"The overall status of the connectivity unit has changed.
Recommended severity level (for filtering): alert"
::= 6
The information in trapd.log looks like this
1190203118 7 Wed Sep 19 12:58:38 2007 192.168.208.242 A fcmgmt 6
6 3 args: [1] 16.0.0.96.105.128.109.226.0.0.0.0.0.0.0.0.21 (Integer): 9
1190203118 7 Wed Sep 19 12:58:38 2007 192.168.208.242 A [2]
16.0.0.96.105.128.109.226.0.0.0.0.0.0.0.0.21 (Integer): 3
1190203118 7 Wed Sep 19 12:58:38 2007 192.168.208.242 A [3]
16.0.0.96.105.128.109.226.0.0.0.0.0.0.0.0.21 (OctetString):
The traps seems to pass on 3 bits of information relating to port status
(9), port state (3) and a blank entry. However, the information in each
line contains the port number 21 at the end of the string of numbers. If
there any way I can pick up this information to forward to tec. I'm not
sure what this information is 16.0.0.96.105.128.109.226.0.0.0.0.0.0.0.0.21
or how I can pick bits out of it.
It would be very useful.
Thanks
Jane
