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

Power Efficiency

• Energy Detect Automatically turns off power on Gigabit Ethernet RJ-45 port when the switch detects a link down Active mode is resumed without loss of any packets when the switch detects the link is back up
• Cable length detection Adjusts the signal strength based on the cable length. Reduces the power consumption for cables shorter than 10 m.

General

• Jumbo frames Frame sizes up to 10 KB supported on 10/100 and Gigabit interfaces
• MAC table Up to 8000 MAC addresses

Discovery

• Link Layer Discovery Protocol (LLDP) (802.1ab) with LLDPMED extensions: LLDP allows the switch to advertise its identification, configuration, and capabilities to neighboring devices, which store the data in an MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP phones.
• Cisco Discovery Protocol The switch advertises itself using the Cisco Discovery Protocol (available April 2011)
