Allow activating SNMP-based LI on routers.
Project description
PyLawful is a small tool converting user inputs into SNMP messages to activate and manage Lawful Intercept Mediation Device and Tap configuration in routers.
The implementation is well proven to work against Cisco IOS-XR routers. It may also work against Cisco IOS, IOS-XE routers or even other vendors. (MIB implementation may vary.)
PyLawful integrates the pysnmp package to build and parse SNMP messages.
The tool allows:
Setting the Target router IP address
Setting the SNMPv3 credentials
Walk the ciscoTap2MIB and ciscoIpTapMIB MIBs
Configure LI MD
Confirure IPv4/IPv6 Tap
Remove MD and/or Taps
List configured Taps
Check cTap2StreamInterceptedPackets stats for configured Taps
