Configuring global LLDP characteristics
Configuring at the global level enables you to apply changes to every port.
To configure the global LLDP characteristics, perform the following steps.
1. Select the DCB tab on the Switch Administration panel.
2. Select the LLDP-DCBX tab.
3. Select the Global tab.
4. Select the LLDP check box to enable LLDP globally.
You can clear the check box to disable LLDP.
5. Enter a name for the configuration in the System Name field.
6. Optionally, add a description in the System 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 of valid values is from 4 to 180 seconds. The
default is 30 seconds.
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 4. 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. In the FC0E Priority Bits field, enter a value that indicates the desired user priority. Each bit
represents a user priority associated with FCoE traffic.
The range of valid values is from 0 through 255. The default is 8.
Even though setting multiple bits is allowed (exercising the full range of values), it doesn't
make sense to set more than one bit, because adapters don't support multiple priorities for
FCoE.
NOTE
Web Tools accepts only decimal values for this option, but the CLI allows only entries in list
format or hexadecimal. For example, if you enter the value 8 (decimal) in Web Tools, CLI
represents it as 3 in list format. If you enter the value 255 (decimal) iin Web Tools, CLI
represents it as 0 1 2 3 4 5 6 7 in list format.
11. Select the parameters you want to exchange.
Note that the term TLV indicates packaging of parameters into a Brocade-specific
Type/Length/Value (TLV):
