The QoS feature classifies and prioritizes traffic throughout a network, establishing an end-to-end traffic priority policy to manage available bandwidth and improve throughput of important data.ĭynamic Configuration Arbiter (DCA) determines the client-specific parameters that are assigned in an authentication session.ĭynamic Host Configuration Protocol (DHCP) server configuration: Switch is automatically configured from a DHCP (Bootp) server, including IP address, subnet mask, default gateway, Timep Server address, and TFTP server address.ĭHCP relay: Forwards client-originated DHCP packets to a DHCP network server.ĭownload operation for copying a software version or files to the switch.ĭHCP snooping: Protects your network from common DHCP attacks, such as address spoofing and repeated address requests.ĭirect Access Memory (DMA): Transmits and receives packets between the CPU and the switch.įault Detection facility, including response policy and the sensitivity level at which a network problem should generate an alert.įDR collects information that is “interesting” at the time of the crash, as well as when the switch is misbehaving, but has not crashed. Virus throttling uses connection-rate filtering to stop the propagation of malicious agents.Ĭonsole interface used to monitor switch and port status, reconfigure the switch, and read the event log through an in-band Telnet or out-of-band connection.Ĭlass of Service (CoS): Provides priority handling of packets traversing the switch, based on the IEEE 802.1p priority carried by each packet.ĬoS messages also include QoS events.
Chassis messages include events on Power Over Ethernet (POE) operation.Ĭonnection-rate filtering: Used on the network edge to protect the network from attack by worm-like malicious code by detecting hosts that are generating IP traffic that exhibits this behavior and (optionally) either throttling or dropping all IP traffic from the offending hosts.Ĭonnection-rate filtering messages include events on virus throttling. Hardware operation, including modules and ports, power supply, fans, transceivers, CPU interrupt errors, switch temperature, and so on. HP does not support the transmission of CDP packets to neighbor devices. ARP packets with invalid IP-to-MAC address bindings advertised in the source protocol address and source physical address fields are discarded.Īuthorization: A connected client must receive authorization through web, AMC, RADIUS-based, TACACS+-based, or 802.1X authentication before it can send traffic to the switch.Ĭisco Discovery Protocol: Supports reading CDP packets received from neighbor devices, enabling a switch to learn about adjacent CDP devices.
Only valid ARP requests and responses are relayed or used to update the local ARP cache.
ACEs specify the filter criteria and an action (permit or deny) to take on a packet if it meets the criteria.Īddress Table Manager: Manages MAC addresses that the switch has learned and are stored in the switch's address table.ĭynamic ARP Protection: Protects the network from ARP cache poisoning. Port-level security that allows LAN access only on ports on which a single 802.1X-capable client (supplicant) has entered valid RADIUS user credentialsĪCLs: Filter layer-3 IP traffic to or from a host to block unwanted IP traffic and block or limit other protocol traffic such as TCP, UDP, IGMP, and ICMP. Client-level security that allows LAN access to 802.1X clients (up to 32 per port) with valid user credentials
