Managing Legacy PDs

The PoE switch automatically detects whether or not a device plugged into
the PoE-enabled port is a valid PD. The switch supports PDs compliant
with the IEEE 802.3af and IEEE 802.3at PoE standards. In addition, the
switch supports legacy PDs that were designed before the IEEE standards
were finalized.
If the switch detects the connected device as an invalid PD, the port
functions as a regular Ethernet port. The PoE feature remains activated on
the port, but no power is delivered to the PD.
To enable the switch to detect legacy PDs as valid PDs, use the POWER-
INLINE ALLOW-LEGACY command to provide power to legacy PDs. See
"POWER-INLINE ALLOW-LEGACY" on page 274. To disable the switch
to detect legacy PDs as valid PDs, use the NO POWER-INLINE ALLOW-
LEGACY command not to provide power to legacy PDs. By default, the
switch detects legacy PDs as valid PDs. See "NO POWER-INLINE
ALLOW-LEGACY" on page 266.
This example enables the switch to detect legacy PDs as valid PDs on port
1 to port 3:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.1-port1.0.3
awplus(config-if)# power-inline allow-legacy
This example disables the switch to detect legacy PDs as valid PDs on
ports 1:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.1
awplus(config-if)# no power-inline allow-legacy
