Hi Lee,
Thanks for the response.
I attempted to track back the defs as you suggested..
I will describe the process in case my method was flawed:
I located where the mac definitions were taking place on the 'working'
machine by searching the Net-SNMP directory (D:\Program
Files\OPENXTRA\NET-SNMP) file contents for "MacAddress ::="
That led me to SNMPv2-TC.txt in D:\Program
Files\OPENXTRA\NET-SNMP\usr\share\snmp\mibs.
Examining that file, I found the same display hint that you showed below.
I then repeated the above process on the machine that was displaying
incorrectly ( format "F0 1F AF nn nn nn " 183 learned
)
It came down the the same file " SNMPv2-TC.txt" in "C:\program files
(x86)\openxtra\net-snmp\usr\share\snmp\mibs"
and it had the same display hint notation.
The interesting thing is that from the old machine (correct display) I can
launch the new machines exec with the command below
\\PCNm\c$\PROGRA~2\OPENXTRA\NET-SNMP\usr\bin\snmptable -m BRIDGE-MIB -v 1
-c <community> <IP> 1.3.6.1.2.1.17.4.3
and the format is incorrect. Likewise when I launch the exec on the old
machine, from the new one, the format is incorrect.
Any other ideas, or ideas on how I can track this down? I am using the
output from this command in a program, and the program is crashing because
the output is different. And, while I could modify the program to accept
either format, Id rather know how to make the 2 PCs format the output data
the same.
thanks again for your help

I'm guessing one or more files on the new machine don't match up with
the files on the old machine & you're missing a display hint on the
new machine.
I have non-standard mib files & locations, so I can't point you to a
set of files to check.
What you'll need to do is find the file where dot1dTpFdbAddress is
defined; for me it's in BRIDGE-MIB.my:
dot1dTpFdbAddress OBJECT-TYPE
SYNTAX MacAddress
MAX-ACCESS read-only
STATUS current
no display hint, so find where MacAddress is defined; probably near
the top of the file:
IMPORTS MacAddress FROM SNMPv2-TC
figure out where SNMPv2-TC comes from, look in there for the
definition of MacAddress
MacAddress ::= TEXTUAL-CONVENTION
DISPLAY-HINT "1x:"
STATUS current
DESCRIPTION
"Represents an 802 MAC address represented in the
`canonical' order defined by IEEE 802.1a, i.e., as if it
were transmitted least significant bit first, even though
802.5 (in contrast to other 802.x protocols) requires MAC
addresses to be transmitted most significant bit first."
SYNTAX OCTET STRING (SIZE (6))
add the display hint if it's missing.
Regards,
Lee
