256 BigIron RX Series Configuration Guide53-1001810-01Configuring LLDP9Use the [no] form of the command to disable the receive only mode.You can list all of the ports individually, use the keyword to to specify ranges of ports, or acombination of both. To apply the configuration to all ports on the device, use the keyword allinstead of listing the ports individually.Enabling and disabling transmit only modeWhen LLDP is enabled on a global basis, by default, each port on the Brocade device will becapable of transmitting and receiving LLDP packets. To change the LLDP operating mode totransmit only mode, simply disable the receive mode. Enter a command such as the following atthe Global CONFIG level of the CLI.FastIron(config)#no lldp enable receive ports e 2/4 e 2/5 e 2/6The above command changes the LLDP operating mode on ports 2/4, 2/5, and 2/6 from transmitand receive mode to transmit only mode. Any incoming LLDP packets will be dropped in software.To change a port’s LLDP operating mode from receive only to transmit only, first disable the receiveonly mode, then enable the transmit only mode. For example, enter commands such as thefollowing at the Global CONFIG level of the CLI.FastIron(config)#no lldp enable receive ports e 2/7 e 2/8FastIron(config)#lldp enable transmit ports e 2/7 e 2/8The above commands change the LLDP operating mode on ports 2/7 and 2/8 from receive onlymode to transmit only mode. Any incoming LLDP packets will be dropped in software. Note that ifyou do not disable receive only mode, you will configure the port to both receive and transmit LLDPpackets.Syntax: [no] lldp enable transmit ports ethernet | allUse the [no] form of the command to disable the transmit only mode.Use the [no] form of the command to disable the receive only mode.You can list all of the ports individually, use the keyword to to specify ranges of ports, or acombination of both. To apply the configuration to all ports on the device, use the keyword allinstead of listing the ports individually.Specifying the maximum number of LLDP neighborsYou can change the limit of the number of LLDP neighbors for which LLDP data will be retained, perdevice as well as per port.Per deviceYou can change the maximum number of neighbors for which LLDP data will be retained for theentire system.For example, to change the maximum number of LLDP neighbors for the entire device to 26, enterthe following command.FastIron(config)#lldp max-total-neighbors 26Syntax: [no] lldp max-total-neighbors Use the [no] form of the command to remove the static configuration and revert to the defaultvalue of 392.
