Walking operations¶
Walk whole MIB¶
Send a series of SNMP GETNEXT requests using the following options:
- with SNMPv3, user ‘usr-md5-none’, MD5 authentication, no privacy
- over IPv4/UDP
- to an Agent at demo.snmplabs.com:161
- for all OIDs in IF-MIB
Functionally similar to:
$ snmpwalk -v3 -lauthNoPriv -u usr-md5-none -A authkey1 -X privkey1
demo.snmplabs.com IF-MIB::
from pysnmp.hlapi.v3arch.asyncore import *
# noinspection PyUnusedLocal,PyUnusedLocal,PyUnusedLocal
def cbFun(snmpEngine, sendRequestHandle, errorIndication,
errorStatus, errorIndex, varBindTable, cbCtx):
if errorIndication:
print(errorIndication)
return
elif errorStatus:
print('%s at %s' % (errorStatus.prettyPrint(),
errorIndex and varBindTable[-1][int(errorIndex) - 1][0] or '?'))
return
else:
for varBindRow in varBindTable:
for varBind in varBindRow:
print(' = '.join([x.prettyPrint() for x in varBind]))
return True # request lower layers to do GETNEXT and call us back
