Protocols

TCP/IP

Layer 2 Switching

Spanning Tree:

Standard 802.1d STP support

Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default

Port Grouping:

Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)

·Up to 4 groups

·Up to 4 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation

VLAN:

Support for up to 128 VLANs simultaneously (out of 4096 VLAN IDs)

Port-based and 802.1Q tag-based VLANs

Voice VLAN:

Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS

Internet Group Management Protocol (IGMP) Versions 1 and 2 Snooping:

IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups

Head-of-Line (HOL) blocking:

HOL blocking prevention

Security

IEEE 802.1X (Authenticator Role):

802.1X: RADIUS authentication and accounting, MD5 hash

Supports time-based 802.1X

Dynamic VLAN assignment

Port Security:

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

Storm Control:

Broadcast, multicast, and unknown unicast

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

IPv6

IPv6:

IPv6 host mode

IPv6 over Ethernet

Dual IPv6/IPv4 stack

IPv6 neighbor and router discovery (ND)

IPv6 stateless address auto-configuration

Duplicate address detection (DAD)

Internet Control Message Protocol (ICMP) version 6

IPv6 over IPv4 network with Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) support

IPv6 QoS

Prioritize IPv6 packets in hardware

Multicast Listener Discovery (MLD) Snooping:

Deliver IPv6 Multicast Packets only to the Required Receivers

IPv6 Applications:

Web, ping, Simple Network Time Protocol (SNTP), Trivial File Transfer Protocol (TFTP), RADIUS, syslog, DNS client
