To configure inline active flow monitoring on MX80 and
MX104 routers:
- Associate a sampling instance with the Forwarding Engine
Processor.
For the MX80:
[edit]
user@host# set chassis tfeb slot 0 sampling-instance sampling-instance
The Forwarding Engine Processor slot is always 0 because MX80 and MX104 routers have only one Packet Forwarding Engine.
In this MX80 configuration, the sampling instance is sample-ins1.
[edit]
user@host# set chassis tfeb slot 0 sampling-instance sample-ins1
For the MX104:
[edit]
user@host# set chassis afeb slot 0 sampling-instance sampling-instance
Note: MX80 and MX104 routers support only one sampling instance.
- Under forwarding-options, configure a sampling instance
for the flow server and inline jflow instances (these be configured
in the following steps):
[edit forwarding-options sampling]
user@host# edit instance inline_sample
- Configure the rate at the
[edit forwarding-options
sampling instance instance-name input] hierarchy level to apply
specific values for the sampling instance sample-ins1.[edit forwarding-options sampling instance sample-ins1 input]
user@host# set rate number
In this configuration, the rate is 1000.
[edit forwarding-options sampling instance sample-ins1 input]
user@host# set rate 1000
- Navigate to the output hierarchy and from there, enable
a flow server and then specify the output address and port:
[edit] forwarding-options sampling instance inline_sample family inet output]
user@host# edit flow-server hostname
[edit forwarding-options sampling instance inline_sample family inet output flow-server hostname]
user@host# set port number
- Return to the output hierarchy and specify the source
address for inline jflow:
[edit forwarding-options sampling instance sample-ins1 family inet output]
user@host# set inline-jflow source-address address
In this configuration, the source address is 10.11.12.13.
[edit forwarding-options sampling instance sample-ins1 family inet output]
user@host# set inline-jflow source-address 10.11.12.13
- Specify the output properties.
The following is an example of the sampling configuration for
an instance that supports inline active flow monitoring on MX80 routers:
[edit forwarding-options]
user@host# show
sampling {
instance {
inline_sample {
input {
rate 1000;
}
family inet{
output {
flow-server 192.168.64.143 {
port 80;
}
inline-jflow {
source-address 10.10.11.12;
}
}
}
}
}
}
Note: You need not configure a Flexible PIC Concentrator (FPC)
slot because MX80 routers have only one Packet Forwarding Engine.
The following considerations apply to the inline flow-monitoring
instance configuration:
