Advanced Command Generator#
Concurrent queries#
Send multiple SNMP GET requests at once using the following options:
with SNMPv2c, community ‘public’
over IPv4/UDP
to multiple Agents at demo.pysnmp.com
for instance of SNMPv2-MIB::sysDescr.0 MIB object
based on asyncio I/O framework
Functionally similar to:
$ snmpget -v2c -c public demo.pysnmp.com:1161 SNMPv2-MIB::sysDescr.0
$ snmpget -v2c -c public demo.pysnmp.com:2161 SNMPv2-MIB::sysDescr.0
$ snmpget -v2c -c public demo.pysnmp.com:3161 SNMPv2-MIB::sysDescr.0

errorIndication, errorStatus, errorIndex, varBinds = await getCmd(
snmpEngine,
