Troubleshooting

Using the Event Log for Troubleshooting Switch Problems

I(information) provides information on normal switch operation.D(debug) is reserved for ProCurve internal diagnostic information.Date is the date in the format mm/dd/yy when an entry is recorded in the log.Time is the time in the format hh:mm:ss when an entry is recorded in the log.

Event Number is the number assigned to an event. You can turn event numbering on and off with the [no] log-numbercommand.

System Module is the internal module (such as “ports:” for port manager) that generated a log entry. If VLANs are configured, then a VLAN name also appears for an event that is specific to an individual VLAN. Table C-1 lists the different system modules with a description of each one.

Event Message is a brief description of the operating event.Table C-1. Event Log System Modules

System	Description	Documented in ProCurve Hardware/
Module		Software guide
802.1x	802.1X authentication: Provides access control on a per-client	Access Security Guide
	or per-port basis:
	• Client-level security that allows LAN access to 802.1X
	clients (up to 32 per port) with valid user credentials
	• Port-level security that allows LAN access only on ports on
	which a single 802.1X-capable client (supplicant) has
	entered valid RADIUS user credentials
acl	Access Control Lists (ACLs): Filter layer-3 IP traffic to or from	Advanced Traffic Management Guide
	a host to block unwanted IP traffic, and block or limit other
	protocol traffic such as TCP, UDP, IGMP, and ICMP. Access
	control entries (ACEs) specify the filter criteria and an action
	(permit or deny) to take on a packet if it meets the criteria.
addrmgr	Address Table Manager: Manages MAC addresses that the	Management and Configuration Guide
	switch has learned and are stored in the switch’s address
	table.
arp-protect	Dynamic ARP Protection: Protects the network from ARP	Access Security Guide
	cache poisoning. Only valid ARP requests and responses are
	relayed or used to update the local ARP cache. ARP packets
	with invalid IP-to-MAC address bindings advertised in the
	source protocol address and source physical address fields
	are discarded.
auth	Authorization: A connected client must receive authorization	Access Security Guide
	through web, AMC, RADIUS-based, TACACS+-based, or
	802.1X authentication before it can send traffic to the switch.
