LLDP-MED attributes advertised by the Brocade device
8
For a PD (Endpoint device), the power level represents the maximum power it can consume
during normal operations in its current configuration, even if its actual power draw at that
instance is less than the advertised power draw.
For a PSE (Network Connectivity device), the power level represents the amount of power that
is available on the port at the time. If the PSE is operating in reduced power (i.e., it is using
backup power), the reduced power capacity is advertised as long as the condition persists.
By default, LLDP-MED power-via-MDI information is automatically advertised when LLDP-MED is
enabled, the port is a POE port, and POE is enabled on the port. To disable this advertisement,
enter a command such as the following.
Brocade(config)#no lldp advertise med-power-via-mdi ports e 2/4 to 2/12
The LLDP-MED power-via-MDI advertisement will appear similar to the following on the remote
device, and in the CLI display output on the Brocade device (show lldp local-info).
Syntax: [no] lldp advertise med-power-via-mdi ports ethernet port-list | all
Displaying LLDP statistics and configuration settings
You can use the following CLI show commands to display information about LLDP settings and
statistics:
• show lldp – Displays a summary of the LLDP configuration settings.
• show lldp statistics – Displays LLDP global and per-port statistics.
• show lldp neighbors – Displays a list of the current LLDP neighbors.
• show lldp neighbors detail – Displays the details of the latest advertisements received from
LLDP neighbors.
• show lldp local-info – Displays the details of the LLDP advertisements that will be transmitted
on each port.
This above show commands are described in this section.
LLDP configuration summary
To display a summary of the LLDP configuration settings on the device, enter the show lldp
command at any level of the CLI.
The following shows an example report.
2 7.0 watts 3.84 – 6.49 watts
3 15.4 watts 6.49 – 12.95 watts
