Troubleshooting Using the Event Log for Troubleshooting Switch Problems System Module cos dca dhcp dhcp v6c download dma fault ffi garp gvrp hpesp idm igmp Description Documented in ProCurve Hardware/ Software guide Class of Service (CoS): Provides priority handling of packets Advanced Traffic Management Guide traversing the switch, based on the IEEE 802.1p priority carried by each packet. CoS messages also include Quality of Service (QoS) events. 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. Dynamic Configuration Arbiter (DCA) determines the client- Access Security Guide specific parameters that are assigned in an authentication session. Dynamic 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. Management and Configuration Guide DHCP for IPv6 prefix assignment IPv6 Configuration Guide Download operation for copying a software version or files to Management and Configuration Guide the switch. Direct Access Memory (DMA): Transmits and receives - packets between the CPU and the switch. Fault Detection facility, including response policy and the Management and Configuration Guide sensitivity level at which a network problem should generate an alert. Find, Fix, and Inform: Event or alert log messages indicating a Installation and Getting Started Guide possible topology loop that cause excessive network activity Management and Configuration Guide and results in the network running slow. FFI messages include events on transceiver connections with other network devices. Generic Attribute Registration Protocol (GARP), defined in the Advanced Traffic Management Guide IEEE 802.1D-1998 standard. GARP VLAN Registration Protocol (GVRP): Manages dynamic Advanced Traffic Management Guide 802.1Q VLAN operations, in which the switch creates temporary VLAN membership on a port to provide a link to another port in the same VLAN on another device. Management module that maintains communication between Installation and Getting Started Guide switch ports. Identity-driven Management: Optional management application used to monitor and control access to switch. Advanced Traffic Management Guide Internet Group Management Protocol: Reduces unnecessary Multicast and Routing Guide bandwidth usage for multicast traffic transmitted from multimedia applications on a per-port basis.
