Passive Flow Monitoring
To perform passive flow monitoring, your system
must meet these minimum requirements:
- JUNOS Release 8.5 or later for passive flow monitoring
support on the MX-series MultiServices routers.
- JUNOS Release 8.4 or later for passive flow monitoring
support on the MultiServices 400 PIC (Type 2).
- JUNOS Release 7.6 or later to clear error and flow statistics
with the clear passive-monitoring statistics command
- JUNOS Release 7.5 or later for support of the dynamic
flow capture (DFC) Management Information Base (MIB)
- JUNOS Release 7.4 or later for dynamic flow capture on
Monitoring Services III PICs installed in T-series and M320 routing
platforms, and port mirroring of IPv6 packets
- JUNOS Release 7.3 or later for passive flow monitoring
on selected Ethernet-based interfaces and filter-based forwarding
on output interfaces
- JUNOS Release 7.1 or later for passive flow monitoring
and flow collection services on Monitoring Services II PICs installed
in T-series and M320 routing platforms
- JUNOS Release 6.4 or later for support of the next-hop
IP address field in flow monitoring version 5 records
- JUNOS Release 6.2 or later for ATM2 intelligent queuing
(IQ) interface passive monitoring, flow collection services, 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 interfaces
into flow records
- JUNOS Release 5.4 or later for the Monitoring Services
PIC
- M40e, M160, M320, MX-series, or T-series routing platform
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)
