Description

Wirespeed routing of IPv4 packets

Up to 32 static routes and up to 32 IP interfaces

Relay of DHCP traffic across IP domains

Relay of broadcast information across Layer 3 domains for application discovery or relaying of BootP/DHCP

packets

SSH secures Telnet traffic to and from the switch; SSH v1 and v2 are supported

SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management

GUI in the switch

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

Allow/disallow routing between IP subnets or directly connected IP networks

PVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN,

supports multiple uplinks

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

Supports RADIUS and TACACS authentication. Switch functions as a client

Broadcast, multicast, and unknown unicast

DoS attack prevention

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

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

4 hardware queues

Strict priority and weighted round-robin (WRR)

Queue assignment based on DSCP and class of service (802.1p/CoS)

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

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