Figure 26-13.  Configuring LLDPDU Transmit and Receive Mode
Configuring Transmit and Receive Mode
Once LLDP is enabled, Dell Force10 systems transmit and receive LLDPDUs by default. You can 
configure the system—at CONFIGURATION level or INTERFACE level—to transmit only by executing 
the command 
mode tx, or receive only by executing the command mode rx. Return to the default with the 
no mode command (Figure 26-14).
