threshold traceroute

threshold traceroute

Defines the alarm thresholds for Traceroute tests on any cell or edge that is assigned this alarm template.

Syntax

threshold traceroute {(hop-rtt <milliseconds>) | (inter-arrival-time <milliseconds>)}

no threshold traceroute {hop-rtt | inter-arrival-time}

Arguments

Table 63: threshold traceroute arguments
Argument	Description
hop-rtt <milliseconds>	The hop round trip time (RTT) threshold in milliseconds for traceroute tests. The valid range is 0 to 780,000. Hop RTT is the round trip time for each hop along the route (UDP outbound and ICMP inbound).
inter-arrival-time <milliseconds>	The inter-arrival-time threshold in milliseconds for traceroute tests. The valid range is 0 to 2147483647. Inter arrival time is the time between tests, and can be used to trigger an alarm when a link is down or a set of endpoints becomes isolated.

Prerequisites

Must be in Chatter Alarm Configuration mode. For information on how to access this mode, see Accessing and exiting command modes.

Occurrence

Use once.

Default

Table 64: Default settings for threshold traceroute command
Argument	Default value
Hop RTT threshold	300 milliseconds
inter arrival time threshold	864 seconds

Description

Defines the alarm thresholds for Traceroute tests on any cell or edge that is assigned this alarm template. Thresholds are defined for each variable measured by Chatter for the traceroute test.

These threshold values are absolute thresholds and used to generate an alarm if absolute alarms are enabled. These threshold values are also used for coloring the absolute topology.

The no command restores the default value for the specified threshold.
