Add or deletes actions (disabling ports, logging events, generating SNMP (Simple Network Management Protocol) traps) to be taken when excessive link flapping is detected.
| ports | Physical ports. |
| port_list | List of ports to set link-flap detection actions upon. |
| all | Sets the configured action for link-flap detection upon all ports in the system. |
| action | Sets actions to be taken when excessive link flapping is detected. |
| add | Adds action(s). |
| delete | Deletes action(s). |
| disable-port | Disables selected ports if link-flap threshold is exceeded. After a port is disabled, the port either stays down for the configured disable time value (set in the configure ports link-flap-detection interval threshold disable-time command) or can be re-enabled manually using the clear ports link-flap-detection status command. |
| log | Generates a log event if link-flap threshold is exceeded. |
| trap | Generates an SNMP trap if link-flap threshold is exceeded. |
| all-actions | Adds or deletes all the actions. |
By default, all actions are turned off.
The following example adds all link-flap actions (disabling ports, logging events, generating SNMP traps) on ports 3–10:
configure ports 3-10 link-flap-detection action add all-actions
