IP Address
Enter this node’s host IP address(es), to be used on this
interface. If the interface is a standby and does not
have an IP address, enter 'Standby.'
An IPv4 address is a string of 4 digits separated with
decimals, in this form:
nnn.nnn.nnn.nnn
An IPV6 address is a string of 8 hexadecimal values
separated with colons, in this form:
xxx:xxx:xxx:xxx:xxx:xxx:xxx:xxx.
For more details of IPv6 address format, see the
Appendix H, “IPv6 Network Support,” on page 521.
NETWORK_FAILURE_DETECTION
When there is a primary and a standby network card,
Serviceguard needs to determine when a card has
failed, so it knows whether to fail traffic over to the
other card. The configuration file specifies one of two
ways to decide when the network interface card has
failed:
• INOUT
• INONLY_OR_INOUT
The default is INOUT.
See “Monitoring LAN Interfaces and Detecting Failure”
on page 101 for more information.
Kind of LAN Traffic
Identify the purpose of the subnet. Valid types include
the following:
• Heartbeat
• Client Traffic
•Standby
This information is used in creating the subnet groupings and
identifying the IP addresses used in the cluster and package
configuration files.
