6 Avaya
Configuration
Avaya has PoE in both a chassis based switch (C460) and fixed switches (C360, P330) as well as 802.3af
capability in the G250 and G350 gateways. They all function the same way using the same CLI. The
output is slightly different and is shown in tables below. PoE is enabled by default, so there is no
configuration needed unless PoE was previously disabled. The P330 (actually called the P333T-PWR) has
two internal power supplies – one for the switching functions and one to provide 802.3af power to the ports.
Redundant power for switching and powering ports is an option using external power supplies. Note that no
power is available to ports on the optional expansion module (X330T16).
To check the PoE state, use the
“show powerinline”
command.
There are four states under the Operational Status column.
Delivering
power means detection has taken place and power is being supplied
Searching
means a non-PoE capable device is attached and the switch keeps “searching” for a valid PD
signature.
Off
means powering that port has been administratively disabled using the
“set port powerinline”
command
Fault
means a problem has been detected and no power is supplied.
The power allocated class column will always display class0. The Cajun switches do not rely on class to
deliver power. This may be used in the future.
To enable or disable power to a port, use the
“set port powerinline”
command.
The
“set port powerinline priority”
command can change the default value of low in the
powering priority. This column is used in the rare case where PD power requests exceed the capacity of
the internal power supply for those ports. Low, high and critical are valid options. If all ports are set to low
priority and more power is requested than can be delivered, power is removed from the highest physical
