Re: ifPhysAddress value shown wrong on NetSNMP client for ifTable

Hi Dave,
      Thanks a lot!. I started using the binary string and it works fine now.

I presume you were expecting to see a value of
    00:10:23:c0:42:5d
?

Because I'd suggest that it is the agent (and the other MIB browser)
that is at fault here.   The value you list above is a hex dump of the
string "00:10:23:c0:42:5d" - i.e. the agent seems to be returning the
ifPhysAddress as a printable string.
  But if you check the specification of the MIB object, it's should actually
be *binary* string (of six octets).   The snmpgetnext command is
interpreting the value as such a binary string (overlength, but it
doesn't worry about that).
