An opensource library to use SNMP get/set/bulk/walk/table more easily in Python
import json
oids = None
with open('OIDS.json', 'r') as file:
oids = json.load(file)GET SNMP Command return the value of a specific OID.
get(oid)
switch = SnmpUtils("10.0.0.1")
switch_name = switch.get(oids['system']['name']) # return name of deviceYou can also use get_by_id(oid, id) which returns the value of the inferior OID.
switch = SnmpUtils("10.0.0.1")
switch_interface_3_description = switch.get_by_id(oids['interfaces']['description'], 3) # return the description of the third interfaceSET SNMP is use for set value of a specific OID.
set(oid, value_type, value)
value_type can be one of i/u/t/a/o/s/x/d/b
switch = SnmpUtils("10.0.0.1")
switch_name = switch.set(oids['system']['name'], 's', "Test")WALK SNMP Command return a dict of all values of inferiors OIDs.
walk(oid)
switch = SnmpUtils("10.0.0.1")
switch_interfaces_description = switch.walk(oids['interfaces']['description']) # return a dict with key/value
for k,v in switch_interfaces_description.items():
print(k,v)
BULK SNMP returns all following items up to a limit for an/several item(s).
bulk(*oids_list)
switch = SnmpUtils("10.0.0.1")
switch_interfaces_description = switch.bulk(oids['interfaces']['description']) #return a dict with description for all interfaces
TABLE SNMP returns list of dicts
get_table(oid, sort_key)
switch = SnmpUtils("10.0.0.1")
switch_interfaces = switch.get_table('1.3.6.1.2.1.2.2') # return list of dicts
You can easily check if a device is online
is_online()
switch = ("10.0.0.1")
if switch.is_online():
print("Switch online")
