Dell C1048P Port Extender Networking Command-Line Reference Guide for the C900 - Page 776

Version 7.4.1.0 Description Introduced on the E-Series. Usage Information With each flap, the system penalizes the interface by assigning a penalty (1024) that decays exponentially depending on the configured half-life. After the accumulated penalty exceeds the suppress threshold value, the interface moves to the Error-Disabled state. This interface state is deemed as "down" by all static/dynamic Layer 2 and Layer 3 protocols. The penalty is exponentially decayed based on the half-life timer. After the penalty decays below the reuse threshold, the interface enables. The configured parameters are as follows: • suppress-threshold should be greater than reuse-threshold • max-suppress-time should be at least 4 times half-life NOTE: You cannot apply dampening on an interface that is monitoring traffic for other interfaces. Example Related Commands Dell(conf-if-te-2/2)# dampening 20 800 4500 120 Dell(conf-if-te-2/2)# • clear dampening - clears the dampening counters on all the interfaces or just the specified interface. • show interfaces dampening - displays interface dampening information. description Assign a descriptive text string to the interface.
