Passive Flow Monitoring

To perform passive flow monitoring, your system must meet these minimum requirements:

• JUNOS Release 6.2 or later for ATM2 Intelligent Queuing (IQ) interface passive monitoring, flow collection, and MPLS label stripping
• JUNOS Release 6.1 or later for MPLS passive monitoring
• JUNOS Release 6.0 or later for the Monitoring Services II PIC
• JUNOS Release 5.7 or later for the automatic insertion of autonomous system (AS) numbers and SNMP index values for input and output interfaces into cflowd records
• JUNOS Release 5.4 or later for the Monitoring Services PIC
• M40e or M160 router with an Internet Processor II ASIC
• Type 1 enhanced FPCs
• Two optical splitters
• One Monitoring Services-related PIC for every OC-3 interface worth of monitored traffic
• A Tunnel Services PIC (required if you wish to send traffic to more than one analyzer)
• A SONET/SDH PIC (OC-3, OC-12, or OC-48) or ATM2 IQ PIC (OC-3 or OC-12) for the input interface
• Outgoing PICs to connect to the cflowd collector or packet analyzer
• cflowd version 5 collector
• ES PIC and packet analyzers (optional)

Active Flow Monitoring

To implement active flow monitoring, your system must meet these minimum requirements:

• JUNOS Release 6.0 or later for the Adaptive Services PIC
• JUNOS Release 5.7 or later for the automatic insertion of autonomous system (AS) numbers and SNMP index values for input and output interfaces into cflowd records, port mirroring to multiple ports, and discard accounting
• JUNOS Release 5.6 or later for the Monitoring Services PIC
• M5, M7i, M10, M10i, M20, M40e, or M160 router with an Internet Processor II ASIC
• Type 1 enhanced FPCs
• Two PICs of your choice: One to receive incoming traffic and one to forward outgoing traffic (the second PIC is not necessary for discard accounting)
• Export PICs to connect to the cflowd collector or packet analyzer
• Tunnel Services PIC (required for multiple port mirroring, otherwise optional)
• cflowd version 5 or 8 collector
• ES PIC and packet analyzers (optional)

Table 6, Table 7, and Table 8 describe the specifications for the Monitoring Services PIC, Monitoring Services II PIC, and Adaptive Services PIC.
