Configuring Health Monitoring Expect Status
When the ACE appliance receives a response from the server, it expects a status code to mark a server
as passed. By default, there are no status codes configured on the ACE appliance. If you do not configure
a status code, any response code from the server is marked as failed.
Expect status codes can be configured for FTP, HTTP, HTTPS, RTSP, SIP-TCP, SIP-UDP, and SMTP
probes.
Use this procedure to configure a single or range of code responses that the ACE appliance expects from
the probe destination.
Assumption
An FTP, HTTP, HTTPS, RTSP, SIP-TCP, SIP-UDP, or SNMP probe has been configured. See
Configuring Health Monitoring for Real Servers, page 6-41 for more information.
Procedure
Step 1 Choose Config > Virtual Contexts > context > Load Balancing > Health Monitoring. The Health
Monitoring table appears.
Step 2 Select the FTP, HTTP, HTTPS, or SMTP probe that you want to configure for expect status codes. The
Expect Status subtable appears.
