Ambiguous ASA Syntax
! Much of ASA syntax is ambiguous, over-determined, or just plain confused.
! Below is one such example.
!
! Name two interfaces using the real/mapped interface delimiter, ','.
! In general, ASA accepts a shocking variety of characters for names.
! Keywords are unreserved.
! Only naming conflicts occur with built-in objects.
!
ASA(config)# int po1.22
ASA(config-subif)# vlan 22

Resolve MIB name to OID in Elixir
# Change MIB extensions from .txt to .mib
copy -r /usr/share/snmp/mibs /home/jstorm/mibs
cd /home/jstorm/mibs
rename '\.txt$' .mib *
# Replace instances of RowStatus with INTEGER in MIBs.
# Otherwise, expect compilation errors.
# Compile dependencies before target MIB (IP-FORWARD-MIB, in this case).
