RE: partial locking

["David B Harrington" <dbharrington@comcast.net>]

Hi Andy,

Please get past your SNMP hangup and concentrate on what people are
actually saying. My concerns remain concerns on systems that do not
even have an SNMP agent on them.

You are assuming I am talking about SNMP and about MIB access. I am
not. 
I am not talking about <get-mib> or <set-mib>.

I am talking about locks. And locks go beyond one protocol-specific
approach to accessing the configuration data on a device.
