Check IP service affinity for Discovery and Orchestration
You can check the IP Services table for a list of IP addresses that are associated with a protocol.
Before you begin
Role required: admin
About this task
The IP Services table maps a port to a protocol. Several mappings are provided by default for commonly used port-protocol combinations, such as port 80 for HTTP, port 22 for SSH, and port 161 for SNMP.
A system property called glide.discovery.ip_service_affinity allows Discovery to remember the last port of the IP address that was discovered.
Important: You should not modify IP services unless your organization uses custom ports.
Procedure
-
Navigate to All > Discovery Definition > IP Services.
-
Filter the list to find the appropriate IP service.
-
Select the name of the service to go to that IP service page.
-
Select the IP Service Affinities tab for the list of IP addresses associated with that service.
