Troubleshooting

Using the Event Log for Troubleshooting Switch Problems

System	Description	Documented in ProCurve Hardware/
Module		Software guide
ip	IP addressing: Configures the switch with an IP address and	Management and Configuration Guide
	subnet mask to communicate on the network and support
	remote management access; configures multiple IP
	addresses on a VLAN.
iplock	IP Lockdown: Prevents IP source address spoofing on a per-	Access Security Guide
	port and per-VLAN basis by forwarding only the IP packets in
	VLAN traffic that contain a known source IP address and MAC
	address binding for the port.
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.
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.
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.
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
maclock	MAC lockdown and MAC lockout	Access Security Guide
	• MAC lockdown prevents station movement and MAC
	address “hijacking” by requiring a MAC address to be used
	only an assigned port on the switch. MAC Lockdown also
	restricts the client device to a specific VLAN.
	• MAC lockout blocks a specific MAC address so that the
	switch drops all traffic to or from the specified address.
mgr	ProCurve Manager (PCM) and ProCurve Manager Plus	Management and Configuration Guide
	(PCM+): Windows-based network management solutions for
	managing and monitoring performance of ProCurve devices.
	PCM messages also include events for configuration
	operations.
