Configuring DCB interfaces
18
The LLDP Configuration dialog box displays.
5. Enter a name for the configuration in the Name field.
6. Optionally, add a description in the Description field.
7. Select the Mode.
For Mode, the choices are Tx (transmit), Rx, (receive) or Both. The default is Both.
8. In the Hello field, enter a time value in seconds.
The Hello value sets the interval between hello bridge protocol data units sent by the root
switch configuration messages. The range is 4 to 180 seconds. The default is the global
configuration range.
9. In the Multiplier field, set the number of consecutive misses allowed before LLDP considers
the interface to be down.
The range is 2 to 10. The default is the global configuration range. The multiplier is related to
the Hello time interval. Using the defaults, you wait four times (the multiplier value) at 30
second intervals (the hello value) before giving up on the interface.
10. Select the parameters you want to exchange.
Note that the term TLV indicates packaging of parameters into a Brocade-specific
Type/Length/Value (TLV).
