Passive Flow Monitoring System Requirements
To perform passive flow monitoring, your system must meet these minimum requirements:
- Junos OS Release 8.5 or later for passive flow monitoring support on the MX Series MultiServices routers
- Junos OS Release 8.4 or later for passive flow monitoring support on the MultiServices 400 PIC (Type 2)
- Junos OS Release 7.6 or later to clear error and flow statistics with the clear passive-monitoring statistics command
- Junos OS Release 7.5 or later for support of the dynamic flow capture (DFC) Management Information Base (MIB)
- Junos OS Release 7.4 or later for dynamic flow capture on Monitoring Services III PICs installed in T Series and M320 routers, and port mirroring of IPv6 packets
- Junos OS Release 7.3 or later for passive flow monitoring on selected Ethernet-based interfaces and filter-based forwarding on output interfaces
- Junos OS Release 7.1 or later for passive flow monitoring and flow collection services on Monitoring Services II PICs installed in T Series and M320 routers
- Junos OS Release 6.4 or later for support of the next-hop IP address field in flow monitoring version 5 records
- Junos OS Release 6.2 or later for ATM2 intelligent queuing (IQ) interface passive monitoring, flow collection services, and MPLS label stripping
- Junos OS Release 6.1 or later for MPLS passive monitoring
- Junos OS Release 6.0 or later for the Monitoring Services II PIC
- Junos OS Release 5.7 or later for the automatic insertion of autonomous system (AS) numbers and SNMP index values for interfaces into flow records
- Junos OS Release 5.4 or later for the Monitoring Services PIC
- M40e, M160, M320, MX Series, or T Series router with an Internet Processor II ASIC or later
- Type 1 enhanced FPCs
- Two optical splitters
- A Tunnel Services PIC (required if you wish to send traffic to more than one analyzer)
- An input interface from the following list:
- SONET/SDH PIC—OC3, OC12, or OC48
- ATM2 IQ PIC—OC3 or OC12
- 4-port Fast Ethernet PIC
- Gigabit Ethernet PIC—4-port with small form-factor pluggable transceiver (SFP) or 10-port with SFP
- 1-port 10-Gigabit Ethernet PIC with XENPAK
- Outgoing PICs to connect to the flow collector or packet analyzer
- Flow monitoring version 5 collector
- ES PIC and packet analyzers (optional)
