=== Syslog Property Filtering
ifdef::topdoc[:imagesdir: {topdoc}../../test/case/ietf_syslog/property_filter]
==== Description
Verify property-filter feature: filtering syslog messages based on various
message properties with different operators, case-insensitivity, and negation.
==== Topology
image::topology.svg[Syslog Property Filtering topology, align=center, scaledwidth=75%]
==== Sequence
. Set up topology and attach to target DUT
. Clean up old log files
. Configure syslog with property filters
. Send test messages
. Verify myapp log contains only myapp messages
. Verify not-error log excludes ERROR messages
. Verify case-test log matches case-insensitive 'warning'
. Verify baseline log contains all messages
