|
Security
|
IEEE 802.1X
|
802.1X - RADIUS authentication; MD5 encryption
|
Access control
|
Access control lists (ACLs) - Drop or rate limit based on:
• Source and destination MAC-based
• Source and destination IP address*
• Protocol*
• ToS/differentiated services code point (DSCP)*
• Port*
• VLAN*
• Ethertype*
|
Availability
|
Link aggregation
|
• Link aggregation using IEEE 802.3ad LACP
• Up to 8 ports in up to 8 trunks
|
Storm control
|
Broadcast, multicast, and unknown unicast
|
Spanning Tree
|
• IEEE 802.1d Spanning Tree
• IEEE 802.1s Multiple Spanning Tree
• IEEE 802.1w Rapid Spanning Tree, Fast Linkover
|
Internet Group Management Protocol (IGMP) snooping
|
IGMP (v1/v2) snooping provides for fast client joins and leaves of multicast streams and limits bandwidth-intensive video traffic to only the requestors
|
QoS
|
Priority levels
|
4 hardware queues
|
Scheduling
|
Priority queuing and weighted round-robin (WRR)
|
Class of service
|
• Port based*
• 802.1p VLAN priority based*

• TCP/ User Datagram Protocol (UDP) port-based*
• DiffServ*
• Classification and re-marking ACLs*
|
Rate limiting
|
• Ingress policer
• Egress rate control
