The following example shows the debug fefd events command.
Dell#debug fefd events
Dell#config
Dell(conf)#int te 1/0
Dell(conf-if-te-1/0)#shutdown
2w1d22h: %SYSTEM-P:CP %IFMGR-5-ASTATE_DN: Changed interface Admin state to down: Te 1/0
Dell(conf-if-te-1/0)#2w1d22h : FEFD state on Te 1/0 changed from ANY to Unknown
2w1d22h: %SYSTEM-P:CP %IFMGR-5-OSTATE_DN: Changed interface state to down: Te 1/0
2w1d22h: %SYSTEM-P:CP %IFMGR-5-OSTATE_DN: Changed interface state to down: Te 4/0
2w1d22h: %SYSTEM-P:CP %IFMGR-5-INACTIVE: Changed Vlan interface state to inactive: Vl 1
2w1d22h : FEFD state on Te 4/0 changed from Bi-directional to Unknown
The following example shows the debug fefd packets command.
