Hierarchy Level


Specify a global IP address monitoring threshold and weight, and the interval between pings (retry-interval) and the number of consecutive ping failures (retry-count) permitted before an IP address is considered unreachable for all IP addresses monitored by the redundancy group. Also specify IP addresses, a monitoring weight, a redundant Ethernet interface number, and a secondary IP monitoring ping source for each IP address, for the redundancy group to monitor.


IPv4 address

The address to be continually monitored for reachability. You also set up a secondary IP address to allow testing from the secondary node.


All monitored object failures, including IP monitoring, are deducted from the redundancy group threshold priority. Other monitored objects include interface monitor, SPU monitor, cold-sync monitor, and NPC monitor (on supported platforms).

interface interface secondary-ip-address ip-address;

Define source address for monitoring packets on secondary link.


Define global threshold for IP monitoring. See global-threshold.

  • Default: 0

  • Range: 0-255


Define global weight for IP monitoring. See global-weight.

  • Default: 255

  • Range: 0-255


Number of retries needed to declare reachablity failure. See retry-count (Chassis Cluster).

  • Default: 5

  • Range: 5-15


Define the time interval in seconds between retries. See retry-interval (Chassis Cluster).

  • Default: 1

  • Range: 1-30
