Configure Filters or Sampling on Aggregated SONET Links

To set up firewall filters or sampling on aggregated SONET interfaces, you must configure the asx interface with these properties. The filters function in the same manner as on other interfaces.

To configure a filter, include the filter statement:

filter {

    input input-filter-name;

    output output-filter-name;

}

You can configure this statement at the following hierarchy levels:

• [edit interfaces asx unit logical-unit-number]
• [edit logical-routers logical-router-name interfaces asx unit logical-unit-number]

You must also configure separate statements that define the properties of the filter. For more information, see the JUNOS Internet Software Configuration Guide: Policy Framework and Examples: Configure Filters or Sampling on Aggregated SONET Links.
