HOL blocking prevention

Security

IEEE 802.1X (Authenticator role)

802.1X: RADIUS authentication, MD5 hash

Port security

Locks MAC addresses to ports, and limits the number of learned MAC addresses

Storm control

Broadcast, multicast, and unknown unicast

DoS prevention

DoS attack prevention

Quality of Service

Priority levels

4 hardware queues

Scheduling

Strict priority and weighted round-robin (WRR)
Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS)

Class of service

Port based, 802.1p VLAN priority based, IPv4/v6 IP precedence/type of service (ToS)/DSCP based, Differentiated Services (DiffServ)

Rate limiting

Ingress policer, per VLAN and per port

Power over Ethernet

802.3af PoE or 802.3at PoE+ delivered over any of the RJ-45 network ports within the listed power budgets

Switches support 802.3af, 802.3at, and Cisco pre-standard (legacy) PoE with maximum power of 30 W per port.
This applies to the following PoE-enabled models; the maximum number of ports providing PoE power simultaneously is determined by the total PoE budget for the switch listed as below:
PoE Power Budget: 192 W
Number of Ports That Support PoE: 48

Pre-standard PoE

Support Cisco Pre-Standard PoE

Intelligent PoE power management

Support the granular power negotiation with CDP/LLDP communication with PD devices after IEEE classification
