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 groups

Storm control

Broadcast, multicast, and unknown unicast

Spanning Tree
