SMTP Server Health Checks
Simple Mail Transfer Protocol is a protocol to transfer e-mail messages between servers reli-
ably and efficiently. This protocol traditionally operates over TCP, port 25 and is documented
in RFC 821. Most e-mail systems that send mail over the Internet use SMTP to send messages
from one server to another; the messages can then be retrieved with an e-mail client using
either POP or IMAP.
Configuring the Switch for SMTP Health Checks
To support SMTP health checking, the network administrator must configure a username:pass-
word value in the switch, using the content option on the SLB real server group menu ( /
cfg/slb/group )
To configure the switch for SMTP health checks:
1. Select the health check menu for the real server group.
2. Set the health check type to SMTP for the real server group..
3. Configure the health check content.
4. Apply and save your configuration.
