Data Sheet
Feature Description
STP Bridge Protocol Data Unit
(BPDU) 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 (SCT) 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 (DSCP)/IP precedence, TCP/ UDP source and destination ports,
802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets,
TCP flag
Quality of Service
Priority levels 4 hardware queues
Scheduling Strict priority and weighted round-robin (WRR)
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 (ToS)/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
