Configuring LLDP
9
Changing a port’s LLDP operating mode
LLDP packets are not exchanged until LLDP is enabled on a global basis. When LLDP is enabled on
a global basis, by default, each port on the Brocade device will be capable of transmitting and
receiving LLDP packets. You can disable a port’s ability to transmit and receive LLDP packets, or
change the operating mode to one of the following:
•
Transmit LLDP information only
•
Receive LLDP information only
You can configure a different operating mode for each port on the Brocade device. For example,
you could disable the receipt and transmission of LLDP packets on port e 2/1, configure port e 2/3
to only receive LLDP packets, and configure port e 2/5 to only transmit LLDP packets.
The following sections show how to change the operating mode.
Enabling and disabling receive and transmit mode
To disable the receipt and transmission of LLDP packets on individual ports, enter a command
such as the following at the Global CONFIG level of the CLI.
FastIron(config)#no lldp enable ports e 2/4 e 2/5
The above command disables LLDP on ports 2/4 and 2/5. These ports will not transmit nor
receive LLDP packets.
To enable LLDP on a port after it has been disabled, enter the following command.
FastIron(config)#lldp enable ports e 2/4
Syntax: [no] lldp enable ports ethernet <slotnum/portnum> | all
Use the [no] form of the command to disable the receipt and transmission of LLDP packets on a
port.
You can list all of the ports individually, use the keyword to to specify ranges of ports, or a
combination of both. To apply the configuration to all ports on the device, use the keyword all
instead of listing the ports individually.
Enabling and disabling receive only mode
When LLDP is enabled on a global basis, by default, each port on the Brocade device will be
capable of transmitting and receiving LLDP packets. To change the LLDP operating mode from
receive and transmit mode to receive only mode, simply disable the transmit mode. Enter a
command such as the following at the Global CONFIG level of the CLI.
FastIron(config)#no lldp enable transmit ports e 2/4 e 2/5 e 2/6
The above command changes the LLDP operating mode on ports 2/4, 2/5, and 2/6 from transmit
and receive mode to receive only mode.
To change a port’s LLDP operating mode from transmit only to receive only, first disable the
transmit only mode, then enable the receive only mode. Enter commands such as the following.
FastIron(config)#no lldp enable transmit ports e 2/7 e 2/8 e 2/9
FastIron(config)#lldp enable receive ports e 2/7 e 2/8 e 2/9
The above commands change the LLDP operating mode on ports 2/7, 2/8, and 2/9, from transmit
only to receive only. Note that if you do not disable the transmit only mode, you will configure the
port to both transmit and receive LLDP packets.
Syntax: [no] lldp enable receive ports ethernet
<slotnum/portnum>
