Troubleshooting

Using the Event Log for Troubleshooting Switch Problems

System	Description	Documented in ProCurve Hardware/
Module		Software guide
snmp	Simple Network Management Protocol: Allows you to manage	Management and Configuration Guide
	the switch from a network management station, including
	support for security features, event reporting, flow sampling,
	and standard MIBs.
sntp	Simple Network Time Protocol: Synchronizes and ensures a	Management and Configuration Guide
	uniform time among interoperating devices.
ssh	Secure Shell version 2 (SSHv2): Provides remote access to	Access Security Guide
	management functions on a switch via encrypted paths
	between the switch and management station clients capable
	of SSH operation.
	SSH messages also include events from the Secure File
	Transfer Protocol (SFTP) feature. SFTP provides a secure
	alternative to TFTP for transferring sensitive information, such
	as switch configuration files, to and from the switch in an SSH
	session.
ssl	Secure Socket Layer Version 3 (SSLv3), including Transport	Access Security Guide
	Layer Security (TLSv1) support: Provides remote web access
	to a switch via encrypted paths between the switch and
	management station clients capable of SSL/TLS operation.
stack	Stack management: Uses a single IP address and standard	Advanced Traffic Management Guide
	network cabling to manage a group (up to 16) of switches in
	the same IP subnet (broadcast domain), resulting in a reduced
	number of IP addresses and simplified management of small
	workgroups for scaling your network to handle increased
	bandwidth demand.
stp	Multiple-instance spanning tree protocol/MSTP (802.1s):	Advanced Traffic Management Guide
	Ensures that only one active path exists between any two
	nodes in a group of VLANs in the network. MSTP operation is
	designed to avoid loops and broadcast storms of duplicate
	messages that can bring down the network.
system	Switch management, including system configuration, switch	Management and Configuration Guide
	bootup, activation of boot ROM image, memory buffers, traffic	Access Security Guide
	and security filters.
	System messages also include events from Management
	interfaces (menu, CLI, web browser, ProCurve Manager) used
	to reconfigure the switch and monitor switch status and
	performance.
tacacs	TACACS+ authentication: A central server is used to control	Access Security Guide
	access to the switches (and other TACACS-aware devices) in
	the network through a switch’s console port (local access) or
	Telnet (remote access).
tcp	Transmission Control Protocol: A transport protocol that runs	Advanced Traffic Management Guide
	on IP and is used to set up connections.
