Release Information

Command introduced in Junos OS Release 9.6. Support for global threshold, current threshold, and weight of each monitored IP address added in Junos OS Release 12.1X47-D10.

Description

Display the status of all monitored IP addresses for a redundancy group.

Options

  • none— Display the status of monitored IP addresses for all redundancy groups on the node.

  • redundancy-group group-number— Display the status of monitored IP addresses under the specified redundancy group.

Output Fields

Table 1 lists the output fields for the show chassis cluster ip-monitoring status command.

Table 1: show chassis cluster ip-monitoring status Output Fields

Field Name

Field Description

Redundancy-group

ID number (0 - 255) of a redundancy group in the cluster.

Global threshold

Failover value for all IP addresses monitored by the redundancy group.

Current threshold

Value equal to the global threshold minus the total weight of the unreachable IP address.

IP Address

Monitored IP address in the redundancy group.

Status

Current reachability state of the monitored IP address.

Values for this field are: reachable, unreachable, and unknown. The status is “unknown” if Packet Forwarding Engines (PFEs) are not yet up and running.

Failure count

Number of attempts to reach an IP address.

Reason

Explanation for the reported status. See Table 2.

Weight

Combined weight (0 - 255) assigned to all monitored IP addresses. A higher weight value indicates greater importance.

Expanded reason output fields for unreachable IP addresses added in Junos OS Release 10.1. You might see any of the following reasons displayed.

Table 2: show chassis cluster ip-monitoring status redundancy group Reason Fields

Reason

Reason Description

No route to host

The router could not resolve the ARP, which is needed to send the ICMP packet to the host with the monitored IP address.

No auxiliary IP found

The redundant Ethernet interface does not have an auxiliary IP address configured.

Reth child not up

A child interface of a redundant Ethernet interface is down.

redundancy-group state unknown

Unable to obtain the state (primary, secondary, secondary-hold, disable) of a redundancy-group.

No reth child MAC address

Could not extract the MAC address of the redundant Ethernet child interface.

Secondary link not monitored

The secondary link might be down (the secondary child interface of a redundant Ethernet interface is either down or non-functional).

Unknown

The IP address has just been configured and the router still does not know the status of this IP.

or

Do not know the exact reason for the failure.
