NOTE
Brocade devices always advertise the power source as "unknown".
•
Power priority
- The in-line power priority level for the PSE or PD:
‐
3 - low
‐
2 - high
‐
1 - critical
‐
unknown
•
Power level
- The total power, in tenths of watts, required by a PD from a PSE, or the total power a
PSE is capable of sourcing over a maximum length cable based on its current configuration.
If the exact power is not known for a PSE or PD, it will advertise the power level associated with its
802.3af power class listed in the following table.
802.3af power classes
TABLE 26
Power class
Minimum power level output at the PSE
Maximum power levels at the PD
0
15.4 watts
0.44 - 12.95 watts
1
4.0 watts
0.44 - 3.84 watts
2
7.0 watts
3.84 - 6.49 watts
3
15.4 watts
6.49 - 12.95 watts
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.
device(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
).
+ MED Extended Power via MDI
Power Type : PSE device
Power Source : Unknown Power Source
Power Priority : Low (3)
Power Value : 6.5 watts (PSE equivalent: 7005 mWatts)
