Troubleshooting

Using the Event Log for Troubleshooting Switch Problems

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.

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
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.
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.
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.
