Juniper MX204 and inline Netflow
For start - configure flow templates
vitalvas@mx204-city17# show services flow-monitoring version-ipfix
template ipfix-ipv4 {
flow-active-timeout 10;
flow-inactive-timeout 10;
template-refresh-rate {
packets 2000;
seconds 30;
}
option-refresh-rate {
packets 8000;
seconds 120;
}
ipv4-template;
}
template ipfix-ipv6 {
flow-active-timeout 10;
flow-inactive-timeout 10;
template-refresh-rate {
packets 2000;
seconds 30;
}
option-refresh-rate {
packets 8000;
seconds 120;
}
ipv6-template;
}
Configure instance for export
vitalvas@mx204-city17# show forwarding-options sampling instance ipfix-inline
input {
rate 1000;
}
family inet {
output {
flow-server 192.0.2.33 {
port 2055;
autonomous-system-type origin;
version-ipfix {
template {
ipfix-ipv4;
}
}
}
inline-jflow {
source-address 192.0.2.1;
}
}
}
family inet6 {
output {
flow-server 192.0.2.33 {
port 2055;
autonomous-system-type origin;
version-ipfix {
template {
ipfix-ipv6;
}
}
}
inline-jflow {
source-address 192.0.2.1;
}
}
}
And enable on chassis
set chassis fpc 0 sampling-instance ipfix-inline
set chassis fpc 0 inline-services report-zero-oif-gw-on-discard
set chassis fpc 0 inline-services flex-flow-sizing
After you can configure sampling on interface or another place
