By default, probe-based failure detection operates by using test addresses. If the NIC driver supports it, link-based failure detection is also enabled automatically.
You cannot disable link-based failure detection if this method is supported by the NIC driver. However, you can select which type of probe-based failure detection to implement.
Before selecting a probe-based detection method, take sure that your probe targets meet the requirements that are listed in Requirements for Choosing Targets for Probe-based Failure Detection.
To use only transitive probing, do the following:
Enable the IPMP property transitive-probing by using SMF commands.
# svccfg -s svc:/network/ipmp setprop config/transitive-probing=true # svcadm refresh svc:/network/ipmp:default
For more information about setting this property, see the in.mpathd (1M) man page.
Remove any existing test addresses that have been configured for the IPMP group.
# ipadm delete-addr address addrobj
where addrobj must refer to an underlying interface that hosts a test address.
To use test addresses to probe for failure, do the following:
If necessary, disable transitive probing by using SMF commands.
# svccfg -s svc:/network/ipmp setprop config/transitive-probing=false # svcadm refresh svc:/network/ipmp:default
Assign test addresses to the underlying interfaces of the IPMP group.
# ipadm create-addr -a address under-interface
where address can be in CIDR notation and under-interface is an underlying interface of the IPMP group.
