Restrictions for DLDP

DLDP is mutually exclusive with UDLD running on the port and some of the other protocol running on the switch.

DLDP is not supported on Distributed trunks that is, cannot be enabled on individual port of a DT trunk.

DLDP is not supported on DYN trunk

DLDP PKT received on a DLDP disabled port will not be forwarded and will be dropped by the switch. If DLDP is globally disabled on the switch, DLDP pkts received will be reforward on the same VLAN.
