If the interface state changes to err-disabled, use the fefd reset [interface] global command to reset these interfaces. The unknown or err-disabled state brings the line protocol down so that the protocols above it can detect that the peer link is down. Table 7.

If FEFD is enabled globally, the FEFD interface configuration overrides global FEFD configuration. • OS10 supports FEFD only on physical interfaces. FEFD is not supported on any other interfaces. However, you can enable FEFD on individual physical interfaces that belong to a port channel. Enable FEFD globally To configure FEFD globally: 1 Do one of the following: • Configure FEFD Normal mode globally using the fefd-global command in CONFIGURATION mode. OS10(Config)# fefd-global • Configure FEFD Normal mode globally using the fefd-global mode normal command in CONFIGURATION mode. OS10(Config)# fefd-global mode normal Layer 2 267
