show linkflap

Examples

This example shows how to display the global status of the link trap detection function:

System(rw)->show linkflap globalstate
Linkflap feature globally disabled

This example shows how to display ports disabled by link flap detection due to a violation:

System(rw)->show linkflap downports
Ports currently held DOWN for Linkflap violations:
None.

This example shows how to display the link flap parameters table:

System(rw)->show linkflap parameters
Linkflap Port Settable Parameter Table (X means error occurred)
Port      LF Status  Actions  Threshold   Interval    Downtime
--------  ---------  -------  ----------  ----------  ----------
ge.1.1    disabled   .......  10          5           300
ge.1.2    enabled    D..S..T  3           5           300
ge.1.3    disabled   ...S..T  10          5           300

show linkflap parameters Output Details provides an explanation of the show linkflap parameters command output.

Output...	What it displays...
Port	Port designation. For a detailed description of possible port-string values, refer to the S-, K-, and 7100 Series Configuration Guide.
LF Status	Link flap enabled state.
Actions	Actions to be taken if the port violates allowed link flap behavior. D = disabled, S = Syslog entry will be generated, T= SNMP trap will be generated.
Threshold	Number of link down transitions necessary to trigger the link flap action.
Interval	Time interval (in seconds) for accumulating link down transitions.
Downtime	Interval (in seconds) port(s) will be held down after a link flap violation.

This example shows how to display the link flap metrics table:

System(rw)->show linkflap metrics
