You must configure the probe-ip property for a DLMP aggregation to enable probing. Otherwise, probing is disabled by default and only link-based failure detection is used. For more information, see Failure Detection in DLMP Aggregation.
The following datalink properties are used to configure probe-based failure detection:
probe-ip – Specifies a comma separated list of source IP addresses and a target IP address or host name. The source IP addresses are used for ICMP probing. The list of source IP addresses is followed by an optional target address. The target IP address must be on the same subnet as the specified source IP address.
You can use + to separate the source from the target. You can specify the targets as an IP address or the host name of the target. For information about how to specify the source address and the target address, see How to Configure Probe-Based Failure Detection for DLMP.
probe-fdt – Specifies the failure detection time. You can configure the expected failure detection time value in seconds. The default value is 10 seconds.
