Configuring a health monitoring method
Load balancing supports multiple health monitoring types. This section describes only the types
supported by IPv4 server load balancing.
• ARP—Monitors the availability of a server through ARP.
• DNS—Monitors the availability of a DNS server through DNS.
• FTP—Monitors the availability of an FTP server through FTP.
• HTTP—Monitors the availability of an HTTP service through HTTP access.
• ICMP—Monitors the reachability of a server by sending ICMP messages.
• IMAP—Monitors the availability of an IMAP server through IMAP.
• POP3—Monitors the availability of a POP3 server through the POP3 application.
• RADIUS—Monitors the availability of a RADIUS server through RADIUS authentication.
• RTSP—Monitors the availability of an RTSP server through the RTSP application.
• SIP—Monitors the availability of a SIP server through the SIP application.
• SMTP—Monitors the availability of an SMTP server through SMTP.
• SNMP—Monitors the availability of an SNMP server through SNMP.
• SSL—Monitors the availability of an SSL server through an SSL connection.
• TCP—Monitors the availability of an application port by establishing TCP connections.
• UDPNORMAL—Monitors the availability of an application port by sending UDP packets.
UDPNORMAL health monitoring does not require server response, so H3C recommends that you
use it together with the ICMP health monitoring type. The reachability of the server is determined
through ICMP detection.
To configure a health monitoring method:
1. Select Load Balance > Health Monitor from the navigation tree.
