2073.0. "Concise ASN.1 vs. plain ASN.1 MIB" by FOUR62::LICAUSE (Al Licause (338-5661)) Fri Jan 10 1992 14:00

With regard to the Cisco private MIB, my customer has asked the question:

What does it mean when we say the MIB's are written in concise ASN.1 format?

Apparently Cisco has told them that they haven't a clue as to what is meant
by concise format and appear to be playing ignorant on the private MIB
variables.

Any comments or explainations as to what is meant by concise ASN.1 format
greatly appreciated.

Thanks,
Al

2073.1MTU expects RFC1212-compliant MIBsTOOK::MCPHERSONScientific progress goes 'Boink!'Fri Jan 10 1992 14:207
To be absolutely unambiguous: the DECmcc MIB Compiler expects definitions to be
in accordance to RFC1212 (aka "Concise MIB Format").   

If you would like to see it, I have copy of the RFC online in
	TOOK::USER$43:[MCPHERSON.PUBLIC]RFC1212.TXT.

    If the Cisco sales people are playing ignorant on the MIB formats
    then they are probably trying to sell their own management station
    to your customer.  If you don't have the mib definition then you won't 
    be able to monitor the box via the SNMP AM. The cisco mib is available 
    to your customer via the internet using ftp from ftp.cisco.com.

2073.3thanks very muchFOUR62::LICAUSEAl Licause (338-5661)Mon Jan 13 1992 10:4310
I'll pass this along to the customer.  I'm certain that Cisco is pushing
the proprietary scheme.

By the way, does anyone know if the MIB available via the internet as per
.2, is the same one listed earlier in this notes file?  If so, I've tried
to compile it and use same with DECmcc.  It has problems as I believe others
have found and reported.

Thanks,

2073.4you can only tell by trying themTOOK::MATTHEWSTue Jan 14 1992 15:4114
    answer to .3.
    
    Al, there is no way to be sure. It is the norm for these vendors to
    post something on the internet and then start changing the agent
    and mibs. It is typical that what is on internet may represent what
    they had a show (ie. Interop) and was never really shipped as a
    product. This is especially so when they are trying to get a specific
    sales advantage. 
    
    We tested a MIB against a CISCO box many months ago. We never got a 
    copy of the MIB and a box to agree. There were always some small
    differences. However, for most objects they worked pretty well.
