• Class of Service (CoS) sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ
• Bandwidth shaping

- Port-based rate limiting provides per-port ingress-/ egress-enforced increased bandwidth
- Classifier-based rate limiting uses an access control list (ACL) to enforce increased bandwidth for ingress traffic on each port
- Reduced bandwidth provides per-port, per-queue egress-based reduced bandwidth

• Remote intelligent mirroring mirrors selected ingress/egress traffic based on an ACL, port, MAC address, or VLAN to a local or remote HPE 8200 zl, 6600, 6200 yl, 5400 zl, 5400R, or 3500 Switch anywhere on the network

• Secure FTP allows secure file transfer to and from the switch; protects against unwanted file downloads or unauthorised copying of a switch configuration file
• Switch management logon security helps secure switch CLI logon by optionally requiring either RADIUS or TACACS+ authentication
• Secure management access delivers secure encryption of all access methods (CLI, GUI, or MIB) through SSHv2, SSL, and/or SNMPv3

• Multiple authentication methods
  • IEEE 802.1X authenticates multiple IEEE 802.1X users per port; prevents a user from “piggybacking” on another user’s authentication
  • Web-based authentication authenticates from Web browser for clients that do not support 802.1X supplicant
  • MAC-based authentication authenticates client with the RADIUS server based on client’s MAC address
  • Concurrent authentication modes enables a switch port to accept up to 32 sessions of 802.1X, Web, and MAC authentication
• Private VLAN provides network security by restricting peer- to-peer communication to prevent a variety of malicious attacks; typically a switch port can only communicate with other ports in the same community and/or an uplink port, regardless of VLAN ID or destination MAC address

Convergence
