■ DSCP – DSCP value used to provide Diffserv node behavior for the specified application
type as defined in IETF RFC 2474. DSCP may contain one of 64 code point values (0 - 63).
A value of 0 represents use of the default DSCP value as defined in RFC 2475.
◆ Policy Port Configuration – Every port may advertise a unique set of network policies or
different attributes for the same network policies, based on the authenticated user identity
or port configuration.
■ Port – The port number for which the configuration applies.
■ Policy ID – The set of policies that apply to a given port. The set of policies is selected by
marking the check boxes that correspond to the required policies.
WEB INTERFACE
To configure LLDP-MED TLVs:
1. Click Configuration, LLDP-MED.
2. Modify any of the timing parameters as required.
3. Set the fast start repeat count, descriptive information for the end- point device, and
policies applied to selected ports.
4. Click Save.
4.12. Power over Ethernet (PoE)
Use the Power Over Ethernet Configuration page to set the maximum PoE power provided to
a port, the maximum power budget for the switch (power available to all RJ-45 ports), the port
PoE operating mode, power allocation priority, and the maximum power allocated to each
port. Different PoE priority on each port can be set to limit the power provisioning, if the
power demand exceeds the power budget.
COMMAND USAGE
◆ The switch can provide DC power to a wide range of connected devices, eliminating the
need for an additional power source and cutting down on the amount of cables attached to
each device. Once configured to supply power, an automatic detection process is initialized
by the switch that is authenticated by a PoE signature from the connected device. Detection
and authentication prevent damage to non-compliant devices (IEEE 802.3af or 802.3at).
◆ This switch supports both the IEEE 802.3af PoE and IEEE 802.3at-2009 PoE Plus
standards. To ensure that the correct power is supplied to powered devices (PD) compliant
with these standards, the first detection pulse from the switch is based on 802.3af to which
the 802.3af PDs will respond normally. It then sends a second PoE Plus pulse that causes an
802.3at PD to respond as a Class 4 device and draw Class 4 current. Afterwards, the switch
