Documentation to integrate Fastnetmon with inline jflow using Juniper MX Series routers (MX5, MX10, MX40, MX80, MX104, MX120, MX240, MX480, MX960).
|
||||
|
||||
In this example, we use rate=10, but you can change to rate=100, depending on your traffic. You need to change fastnetmon.conf netflow_sampling_ratio with same rate you setup on your MX router.
|
||||
|
||||
Our topology is two MX80 routers, named r1 and r2. From each router connected directly to Fastnetmon server.
|
||||
|
||||
Fastnetmon server have 2 interfaces:
|
||||
10.50.1.2/30 - connected to r1
|
||||
10.50.1.6/30 - connected to r2
|
||||
c
|
||||
R1 have 1 transit connected to ge-1/0/0.0
|
||||
R2 have 1 transit connected to ge-1/0/0.0
|
||||
|
||||
Setting sampling on transit interfaces. Run that on those interfaces on each router.
|
||||
|
||||
```
|
||||
set interfaces ge-1/0/0.0 family inet sampling input
|
||||
```
|
||||
|
||||
|
||||
You can check https://github.com/FastVPSEestiOu/fastnetmon/blob/master/docs/DOCKER_INSTALL.md to see how to configure Fastnetmon to work with inline-jflow
|
||||
|
||||
```
|
||||
r1# show interfaces ge-1/0/4
|
||||
unit 0 {
|
||||
description netflow-collector;
|
||||
family inet {
|
||||
address 10.50.1.1/30;
|
||||
}
|
||||
}
|
||||
|
||||
|
||||
|
||||
r1# show interfaces ge-1/0/4 | display set
|
||||
set interfaces ge-1/0/4 unit 0 description netflow-collector
|
||||
set interfaces ge-1/0/4 unit 0 family inet address 10.50.1.1/30
|
||||
|
||||
r2# show interfaces ge-1/0/4
|
||||
unit 0 {
|
||||
description netflow-collector;
|
||||
family inet {
|
||||
address 10.50.1.5/30;
|
||||
}
|
||||
}
|
||||
r2# show interfaces ge-1/0/4 | display set
|
||||
set interfaces ge-1/0/4 unit 0 description netflow-collector
|
||||
set interfaces ge-1/0/4 unit 0 family inet address 10.50.1.5/30
|
||||
```
|
||||
|
||||
Now add templates configuration on r1 and r2. Take care of flow-active-timeout and flow-inactive-timeout it should be less than average_calculation_time. Try average_calculation_time=20 where flow-active-timeout=10:
|
||||
```
|
||||
set services flow-monitoring version-ipfix template ipv4 flow-active-timeout 10
|
||||
set services flow-monitoring version-ipfix template ipv4 flow-inactive-timeout 10
|
||||
set services flow-monitoring version-ipfix template ipv4 template-refresh-rate packets 1000
|
||||
set services flow-monitoring version-ipfix template ipv4 template-refresh-rate seconds 10
|
||||
set services flow-monitoring version-ipfix template ipv4 option-refresh-rate packets 1000
|
||||
set services flow-monitoring version-ipfix template ipv4 option-refresh-rate seconds 10
|
||||
set services flow-monitoring version-ipfix template ipv4 ipv4-template
|
||||
set chassis tfeb slot 0 sampling-instance ipfix
|
||||
|
||||
|
||||
flow-monitoring {
|
||||
version-ipfix {
|
||||
template ipv4 {
|
||||
flow-active-timeout 60;
|
||||
flow-inactive-timeout 60;
|
||||
template-refresh-rate {
|
||||
packets 1000;
|
||||
seconds 10;
|
||||
}
|
||||
option-refresh-rate {
|
||||
packets 1000;
|
||||
seconds 10;
|
||||
}
|
||||
ipv4-template;
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
slot 0 {
|
||||
sampling-instance ipfix;
|
||||
}
|
||||
|
||||
|
||||
```
|
||||
|
||||
|
||||
Now setup ipfix exports:
|
||||
```
|
||||
r1# show forwarding-options
|
||||
sampling {
|
||||
instance {
|
||||
ipfix {
|
||||
input {
|
||||
rate 10;
|
||||
}
|
||||
family inet {
|
||||
output {
|
||||
flow-server 10.50.1.2 {
|
||||
port 2055;
|
||||
version-ipfix {
|
||||
template {
|
||||
ipv4;
|
||||
}
|
||||
}
|
||||
}
|
||||
inline-jflow {
|
||||
source-address 10.50.1.1;
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
r1# show forwarding-options | display set
|
||||
set forwarding-options sampling instance ipfix input rate 10
|
||||
set forwarding-options sampling instance ipfix family inet output flow-server 10.50.1.2 port 2055
|
||||
set forwarding-options sampling instance ipfix family inet output flow-server 10.50.1.2 version-ipfix template ipv4
|
||||
set forwarding-options sampling instance ipfix family inet output inline-jflow source-address 10.50.1.1
|
||||
|
||||
|
||||
r2# show forwarding-options
|
||||
sampling {
|
||||
instance {
|
||||
ipfix {
|
||||
input {
|
||||
rate 10;
|
||||
}
|
||||
family inet {
|
||||
output {
|
||||
flow-server 10.50.1.6 {
|
||||
port 2055;
|
||||
version-ipfix {
|
||||
template {
|
||||
ipv4;
|

}
|
||||
}
|
||||
}
|
||||
inline-jflow {
|
||||
source-address 10.50.1.5;
|

}
|

}
|

}
|

}
|

}
|
||||
}
|
||||
|
||||
r2# show forwarding-options | display set
|
||||
set forwarding-options sampling instance ipfix input rate 10
|
||||
set forwarding-options sampling instance ipfix family inet output flow-server 10.50.1.6 port 2055
|
||||
set forwarding-options sampling instance ipfix family inet output flow-server 10.50.1.6 version-ipfix template ipv4
|
||||
set forwarding-options sampling instance ipfix family inet output inline-jflow source-address 10.50.1.5
