Miscellaneous health check settings
Basing an alias port’s health on the health of its
master port
By default, the Brocade Virtual ADX performs health checks for alias ports independently of the
master ports on which they are based. For example, if you configure alias port 8080 and base the
port on port 80 (its master port), the Brocade Virtual ADX checks the health of 80 and 8080
independently.
You can configure the Brocade Virtual ADX to check the health of the master port only and base the
health of the alias ports on the master port.
You can base an alias port’s health on the health of one of the following TCP ports:
• FTP – port 21 (ports 20 and 21 both are FTP ports but on the Brocade Virtual ADX, the name
“FTP” corresponds to port 21)
• HTTP – port 80
• IMAP4 – port 143
• LDAP – port 389
• MMS – port 1755
• NNTP – port 119
• PNM – port 7070
• POP3 – port 110
• RTSP – port 554
• SMTP – port 25
• SSL – port 443
• TELNET – port 23
You cannot base an alias port’s health on the health of a UDP port or a port that is not well-known
to the Brocade Virtual ADX.
NOTE
The health checks for the alias ports must be enabled. Otherwise, the Brocade Virtual ADX will not
check the master port’s state, and the alias port will not go down when the master port goes down.
To configure an alias port’s health to be based on its master port’s health, edit the alias port’s
profile by entering commands such as the following.
Virtual ADX(config)#server port 8080
Virtual ADX(config-port-8080)#tcp keepalive use-master-state
Syntax: [no] tcp keepalive use-master-state
The command is entered at the port profile level.
