> something wrong with just using another hash for your hash/values?

Maybe I am misunderstanding your reply, but I do not see how using multiple hashes would work with the foreach loop. From what I understand, your suggestion would look something like:

foreach my $oid (sort keys(%iface)) {
  %oids = ("$iface{$oid}" => `$snmpwalk $ip $community $oid`);
  %oid2 = ("$iface{$oid}" => `$snmpwalk $ip $community $oid`);
  %oid3 = ("$iface{$oid}" => `$snmpwalk $ip $community $oid`);
}

It seems possible that I could "hard code" it without using the foreach loop, but the values of the %iface hash will not be constant, so I really must keep the code flexible, if you know what I mean.
