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
