| Layer 2 Switching |
- VLAN support and tagging — supports IEEE 802.1Q
- GARP VLAN Registration Protocol — allows automatic learning and dynamic assignment of VLANs
- IEEE 802.1v protocol VLANs — isolate select non-IPv4 protocols automatically into their own VLANs
|
| Số địa chỉ MAC |
8000 entries |
| Số VLAN |
4,094 VLAN IDs and 256 VLANs simultaneously |
| Nhóm Trunking |
IEEE 802.3ad Link Aggregation Protocol (LACP) and HP port trunking — support up to 24 trunks, each with up to 8 links (ports) per trunk |
| Layer 3 Switching |
Basic IP routing — enables automatic routing to the connected VLANs and up to 16 static routes, including one default route, in IP networks |
| Convergence |
- IEEE 802.1AB Link Layer Discovery Protocol (LLDP) — is an automated device discovery protocol that provides easy mapping of network management applications
- LLDP-MED (Media Endpoint Discovery) — is a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure network devices such as IP phones
- IP multicast snooping and data-driven IGMP — automatically prevent flooding of IP multicast traffic

| Bảo mật |
- Multiple user authentication methods —
- IEEE 802.1X — is an industry-standard method of user authentication using an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server
- Web-based authentication — similar to IEEE 802.1X, it provides a browser-based environment to authenticate clients that do not support the IEEE 802.1X supplicant
- MAC-based authentication — client is authenticated with the RADIUS server based on the client's MAC address
- Authentication flexibility —
- Multiple IEEE 802.1X users per port — provides authentication of up to eight IEEE 802.1X users per port; prevents user "piggybacking" on another user's IEEE 802.1X authentication
- Concurrent IEEE 802.1X and Web or MAC authentication schemes per port — switch port will accept any of IEEE 802.1X and either Web or MAC authentications
- Access control lists (ACLs) — provide IP Layer 3 filtering based on source/destination IP address/subnet and source/destination TCP/UDP port number
- Identity-driven ACL — enables implementation of a highly granular and flexible access security policy and VLAN assignment specific to each authenticated network user
- Dynamic ARP protection — blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data
- Port security — allows access only to specified MAC addresses, which can be learned or specified by the administrator
- MAC address lockout — prevents particular configured MAC addresses from connecting to the network
- Source-port filtering — allows only specified ports to communicate with each other
- RADIUS/TACACS+ — eases switch management security administration by using a password authentication server
- Secure Shell — encrypts all transmitted data for secure remote CLI access over IP networks
- Port monitoring for network threats — provides sampled port traffic using sFlow technology to the HP Network Immunity Manager application for Network Behavior Anomaly Detection (NBAD) analysis to detect threats and mitigate threats at the port where they originated
- Secure Sockets Layer (SSL) — encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch
- Secure FTP — allows secure file transfer to and from the switch; protects against unwanted file downloads or unauthorized copying of a switch configuration file
- Switch management logon security — can require either RADIUS or TACACS+ authentication for secure switch CLI logon
- DHCP protection — blocks DHCP packets from unauthorized DHCP servers, preventing denial-of-service attacks
- STP BPDU port protection — blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks
- STP Root Guard — protects the root bridge from malicious attack or configuration mistakes

| Khả năng xếp chồng |
- Single IP Address Management — single IP address management for a virtual stack of up to 16 switches
|
| Quản lý |
- RMON, XRMON, and sFlow — provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events
- Uni-Directional Link Detection (UDLD) — monitors a link between two switches and blocks the ports on both ends of the link if the link goes down at any point between the two devices
- Command authorization — leverages RADIUS to link a custom list of CLI commands to individual network administrator's login; also provides an audit trail
- Multiple configuration files — allow multiple configuration files to be stored to a flash image
- Dual flash images — provides independent primary and secondary operating system files for backup while upgrading
- Friendly port names — allow assignment of descriptive names to ports
- Find-Fix-Inform — finds and fixes common network problems automatically, then informs administrator
- Software updates — free downloads from the Web
- Troubleshooting — ingress and egress port monitoring enable network problem solving
