=== Syslog Hostname Filtering
2+
3+
ifdef::topdoc[:imagesdir: {topdoc}../../test/case/ietf_syslog/hostname_filter]
4+
5+
==== Description
6+
7+
Verify hostname-filter feature: filtering incoming syslog messages based
8+
on the hostname. Tests log sink scenario with multiple remote clients.
9+
10+
==== Topology
11+
12+
image::topology.svg[Syslog Hostname Filtering topology, align=center, scaledwidth=75%]
13+
14+
==== Sequence
15+
16+
. Set up topology and attach to DUTs
17+
. Clean up old log files on server
18+
. Configure server as syslog sink with hostname filtering
19+
. Configure client to forward logs to server
20+
. Send log messages with different hostnames
21+
. Verify router1 log contains only router1 messages
22+
. Verify router2 log contains only router2 messages
23+
. Verify all-hosts log contains all messages
