automatically shuts down user ports if an STP
BPDU packet is seen to prevent topology loops

becoming STP root node
Converged networks
PoE
• The PoE models support Alcatel-Lucent IP
phones and WLAN access points, as well as
any end device compliant with IEEE 802.3af
or IEEE 802.3at compliant end device.
• Configurable per-port PoE priority and max
power for power allocation
• Dynamic PoE allocation delivers only the power
needed by the device up to the total power bud-
get for the most efficient power consumption.
QoS
• Priority queues: Eight hardware-based queues
per port for flexible QoS management
• Traffic prioritization: Flow-based QoS with
internal and external (re-marking) prioritization

and port based bandwidth management for both
ingress rate limiting and/or egress rate shaping
• Queue management: Configurable scheduling
algorithm – Strict Priority, Weighted Round
Robin (WRR) and Deficit Round Robin (DRR)
• Congestion avoidance: Support for End-to-End
Head-of-Line (E2E-HOL) Blocking Protection
• Auto-QoS for switch management traffic as
well as traffic from Alcatel-Lucent IP phones
• Three-color marker – Single/Dual Rate – polic-
ing with Commit BW, Excess BW, Burst Size
