Feature Description
Layer 3
IPv4 routing Wirespeed routing of IPv4 packets
Up to 32 static routes and up to 32 IP interfaces
Classless Inter-Domain Routing (CIDR) Support for CIDR
DHCP relay at Layer 3 Relay of DHCP traffic across IP domains
User Datagram Protocol (UDP) relay Relay of broadcast information across Layer 3 domains for application discovery or relaying of BootP/DHCP
packets
Security
Secure Shell (SSH) Protocol SSH secures Telnet traffic to and from the switch; SSH v1 and v2 are supported
Secure Sockets Layer (SSL) SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management
GUI in the switch
IEEE 802.1X
(Authenticator role)
802.1X: RADIUS authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN,
single/multiple host mode and single/multiple sessions
Supports time-based 802.1X
Dynamic VLAN assignment
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
