Re: [Netdisco] Nortel 5510 switch support

[Eric M. <er...@je...>]

Thanks for bringing this up.  I knew it was coming when Nortel announced name
changes for everything including the company itself.  I guess the marketing
gurus didn't think customers knew they were buying an Ethernet switch unless
they named it Ethernet Switch :->

I have modified snmp-info to recognize the new names and models.  I have also
modified it to work with 5510/5520/5530 in Layer 3.  These changes have been
uploaded to CVS.  If you have a 5520 actually performing Layer 3 functions, I
would like to validate that services reports correctly.  We are not using the
functionality and all out 5510's report they only perform Layer 2.

I have also uploaded the newer SYNOPTICS-ROOT-MIB (synro.mib) to CVS this will
eliminate the sysObjectID issue.

I have validated the changes did not break any existing functionality, I would
appreciate if you could validate it corrects your issues.

Thanks,
Eric
