Parameters
auto
: Specifies the auto mode. In this mode, when DLDP detects a unidirectional link, it shuts down
the unidirectional port. When the link becomes bidirectional, DLDP brings up the port that was shut
down.
hybrid
: Specifies the hybrid mode. In this mode, when DLDP detects a unidirectional link, it shuts
down the unidirectional port and stops link detection. To verify the link status, use the
undo
shutdown
command to bring up the port. If the link becomes bidirectional, the port becomes
bidirectional.
manual
: Specifies the manual mode. In this mode, when DLDP detects a unidirectional link, it does
not shut down the involved port. You must manually shut it down. To verify the link status, use the
undo shutdown
command to bring up the port. If the link becomes bidirectional, the port becomes
bidirectional.
Usage guidelines
If DLDP detects a unidirectional link, you must troubleshoot the interface and cabling faults.
The global port shutdown mode setting takes effect on all interfaces and has lower priority than the
port shutdown mode setting for an interface.

# Set the global port shutdown mode to manual mode.
