Net-SNMP examples using the allied MIB directory Show commands

These commands use the standard Observium installation path and load the selected MIB variant before the RFC and Net-SNMP directories.

Translate the module identity

/usr/bin/snmptranslate -Pud -Ir -On -m 'AT-DHCPSN-MIB' -M '/opt/observium/mibs/allied:/opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp' 'AT-DHCPSN-MIB::atDhcpsn'

Walk the MIB subtree

/usr/bin/snmpbulkwalk -v2c -c '<community>' -Pud -Ir -OQUs -m 'AT-DHCPSN-MIB' -M '/opt/observium/mibs/allied:/opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp' 'udp:<hostname>:161' 'AT-DHCPSN-MIB::atDhcpsn'
