Make sure that your snmp.conf is updated to point to your MIB
directory and that the MIBs are world-readable.
DESIGN GOALS
1. Use of textual MIB leaf identifier and enumerated values
* All values are retrieved via MIB Leaf node names
* All values are retrieved via MIB Leaf node names
For example SNMP::Info has an entry in its %GLOBALS hash for
``sysName'' instead of 1.3.6.1.2.1.1.5.
* Data returned is in the enumerated value form.
* Data returned is in the enumerated value form.
For Example instead of looking up 1.3.6.1.2.1.2.2.1.3 and
getting back 23
getting back `23'
SNMP::Info will ask for "RFC1213-MIB::ifType" and will get back
"ppp".
