Dell Configuration Guide for the S4048–ON System 9.14.2.4

Example of Verifying the System is not Caching Local Sources

When you apply this filter, the SA cache is not affected immediately. When sources that are denied by the ACL time out, they are not refreshed. Until they time out, they continue to reside in the cache. To apply the redistribute filter to entries already present in the SA cache, first clear the SA cache. You may optionally store denied sources in the rejected SA cache.
