blocks DHCP packets from unauthorized DHCP servers, preventing denial-of-service attacks
Dynamic ARP protection:
blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data

Resiliency and high availability
Port trunking and link aggregation
o Trunking
supports up to eight links per trunk to increase bandwidth and create redundant connections; supports L2, L3,
and L4 trunk load-balancing algorithm (L4 trunk load balancing is supported only on Gigabit Ethernet and 48-
port models)
and L4 trunk load-balancing algorithm (L4 trunk load balancing is supported only on Gigabit Ethernet and 48-
port models)
o IEEE 802.3ad Link Aggregation Protocol (LACP)
eases configuration of trunks through automatic configuration
IEEE 802.1s Multiple Spanning Tree
provides high link availability in multiple VLAN environments by allowing multiple spanning trees; provides legacy
support for IEEE 802.1d and IEEE 802.1w

Product Architecture
Energy-efficient design
o IEEE 802.3az
reduces power consumption during periods of low data activity on Gigabit Ethernet switches
o Port low power mode
allows the port to automatically go into low-power mode to conserve energy when no link is detected
o Fans
decreases power consumption in fanless (all 8-port, 2530-24, and 2530-48 switches) and variable-speed fan
switches
switches
o Port LEDs
conserves energy by optionally turning off port link and activity LEDs
