Supports time-based 802.1X

Dynamic VLAN assignment

STP Bridge Protocol Data Unit Guard: A security mechanism to protect the network from invalid configurations.

A port enabled for BPDU Guard is shut down if a BPDU message is received on that port

Secure Core Technology: Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received

Layer 3 Isolation: Allow/disallow routing between IP subnets or directly connected IP networks

Layer 2 Isolation Private VLAN Edge (PVE) with community VLAN: PVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinks

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

RADIUS/TACACS+: Supports RADIUS and TACACS authentication. Switch functions as a client

Storm Control: Broadcast, multicast and unknown unicast

DoS Prevention: DoS attack prevention

Congestion Avoidance: A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization.

ACLs: Support for up to 512 rules

Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, differentiated services code point/IP precedence, TCP/ UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol packets, IGMP packets, TCP flag

Quality of Service

Priority Levels: 4 hardware queues

Scheduling: Strict priority and weighted round-robin

Queue assignment based on 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/DSCP based; Differentiated Services (DiffServ); classification and re-marking ACLs, trusted QoS

Rate Limiting: Ingress policer; egress shaping and rate control; per VLAN, per port and flow based
