Tracked Object Manager allocates a probe entry for each client application. A preset default ICMP probe for each supported application exists when you boot your system, although not all client applications may use their default probe. You cannot modify or delete default ICMP probes.
How a default ICMP probe is handled depends upon the application the default probe is associated with. Default ICMP probes associated with non-server-based applications such as policy based routing and VRRP are manually applied. On the S-Series platform, default ICMP probes associated with server-based applications such as server load balancing and TWCB are auto-applied.
Use the show probe default command to display a list of the current default probes. Use the show probe probe-name detail command to display the description and attributes of the default probes.
