Troubleshooting

Using the Event Log for Troubleshooting Switch Problems

System	Description	Documented in ProCurve Hardware/
Module		Software guide
cdp	Cisco Discovery Protocol: Supports reading CDP packets	Management and Configuration Guide
	received from neighbor devices, enabling a switch to learn
	about adjacent CDP devices. ProCurve switches do not
	support the transmission of CDP packets to neighbor devices.
chassis	Hardware operation, including modules and ports, power	Installation Guides
	supply, fans, transceivers, CPU interrupt errors, switch	Management and Configuration Guide
	temperature, and so on. Chassis messages include events on
	Power Over Ethernet (POE) operation.
connfilt	Connection-Rate filtering: Used on the network edge to	Access Security Guide
	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.
	Connection-Rate filtering messages include events on virus
	throttling. Virus throttling uses connection-rate filtering to
	stop the propagation of malicious agents.
console	Console interface used to monitor switch and port status,	Installation and Getting Started Guide
	reconfigure the switch, read the event log through an in-band
	Telnet or out-of-band connection.
cos	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.
dca	Dynamic Configuration Arbiter (DCA) determines the client-	Access Security Guide
	specific parameters that are assigned in an authentication
	session.
dhcp	Dynamic Host Configuration Protocol (DHCP) server	Management and Configuration Guide
	configuration: Switch is automatically configured from a
	DHCP (Bootp) server, including IP address, subnet mask,
	default gateway, Timep Server address, and TFTP server
	address.
dhcp v6c	DHCP for IPv6 prefix assignment	IPv6 Configuration Guide
dhcpr	DHCP relay: Forwards client-originated DHCP packets to a	Advanced Traffic Management Guide
	DHCP network server.
download	Download operation for copying a software version or files to	Management and Configuration Guide
	the switch.
dhcp-snoop	DHCP snooping: Protects your network from common DHCP	Access Security Guide
	attacks, such as address spoofing and repeated address
	requests.
