Applying a Firewall Filter Output Interface on an M, MX or T Series Router to Port-mirror Traffic to PICs or Flow Collection Services
On output interfaces, you can apply a firewall
filter that leads to a filter-based forwarding routing instance. This
is useful if you want to port-mirror traffic to multiple Monitoring
Services PICs or flow collection services interfaces. To configure,
include the output
statement at the [edit interfaces interface-name unit logical-unit-number family inet filter]
hierarchy level.
[edit] interfaces fe-3/1/0 { description “export interface to flow collection services interfaces”; unit 0 { family inet; address ip-address; filter { output output-filter-name; } } }
