Troubleshooting

Using the Event Log for Troubleshooting Switch Problems

System	Description	Documented in ProCurve Hardware/
Module		Software guide
igmp	Internet Group Management Protocol: Reduces unnecessary	Multicast and Routing Guide
	bandwidth usage for multicast traffic transmitted from
	multimedia applications on a per-port basis.
ip	IP addressing: Configures the switch with an IP address and	Management and Configuration Guide
	subnet mask to communicate on the network and support	Multicast and Routing Guide
	remote management access; configures multiple IP
	addresses on a VLAN; enables IP routing on the switch.
ipaddrmgr	IP Address Manager: Programs IP routing information in	Multicast and Routing Guide
	switch hardware.
ipx	Novell Netware protocol filtering: On the basis of protocol	Access Security Guide
	type, the switch can forward or drop traffic to a specific set of
	destination ports on the switch.
kms	Key Management System: Configures and maintains security	Access Security Guide
	information (keys) for all routing protocols, including a timing
	mechanism for activating and deactivating an individual
	protocol.
lacp	LACP trunks: The switch can either automatically establish an	Management and Configuration Guide
	802.3ad-compliant trunk group or provide a manually
	configured, static LACP trunk.
ldbal	Load balancing in LACP port trunks or 802.1s Multiple	Management and Configuration Guide
	Spanning Tree protocol (MSTP) that uses VLANs in a network	Advanced Traffic Management Guide
	to improve network resource utilization and maintain a loop-
	free environment.
	Load-balancing messages also include switch meshing
	events. The Switch Meshing feature provides redundant links,
	improved bandwidth use, and support for different port types
	and speeds.
lldp	Link-Layer Discovery Protocol: Supports transmitting LLDP	Management and Configuration Guide
	packets to neighbor devices and reading LLDP packets
	received from neighbor devices, enabling a switch to
	advertise itself to adjacent devices and to learn about
	adjacent LLDP devices.
loop_protect	Loop protection: Detects the formation of loops when an	Advanced Traffic Management Guide
	unmanaged device on the network drops spanning tree
	packets, and provides protection by transmitting loop protocol
	packets out ports on which loop protection has been enabled.
macauth	Web and MAC authentication: Port-based security employed	Access Security Guide
	on the network edge to protect private networks and the
	switch itself from unauthorized access using one of the
	following interfaces:
	• Web page login to authenticate users for access to the
	network
	• RADIUS server that uses a device’s MAC address for
	authentication
