Net-SNMP Command-Line Tools
This section briefly
describes each of the Net-SNMP tools. By default, installing Net-SNMP
places all these commands in /usr/local/bin. All
the examples in this section assume that
/usr/local/bin is in your path.
snmpwalk
snmpwalk performs the get-next operation. We’ve used it throughout the book, so it should be familiar; in this section, we’ll use it to demonstrate some of the options introduced in Table C-1.
