Hi Robert, Thank you for the reply.
We already tried that and it failed. I did have a look at the code and the reason is that it is not just a Perl (regex) substitution, if that is what you meant. Extracting content from inside the brackets is achieved in the "lib/perl/xCAT/Table.pm" file using the 'extract_bracketed' function. I did not want to bother with Text::Balanced too much because our main goal is not at generalizing xCat's functionality, but to adapt to our needs to get it working with our hardware. I managed to solve the brackets problem in the switch table - it is a specific fix. I added the following in "lib/perl/xCAT/MacMap.pm": return 1 if $namepersnmp =~ /$namepercfg/ (inside of sub namesmatch() (somewhere around lines 106-107)). In the switch table, I've substituted the "escaped brackets" with a '.' (any character). This was probably not strictly required because the escaped brackets would probably also work in this case. Anyway, this works fine now. We are using a Nortel switch 5530 (Avaya) and that is why we had the switch output the SNMP data with brackets (with relation to the mac-port discovery process).

I think it's just a Perl substitution so the brackets don't have any special meaning in the second part. ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
