Troubleshooting Using the Event Log for Troubleshooting Switch Problems 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-number command. 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 Module 802.1x addrmgr auth cdp chassis console Description Documented in ProCurve Hardware/ Software guide 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 Address Table Manager: Manages MAC addresses that the Management and Configuration Guide switch has learned and are stored in the switch's address table. 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. 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. Hardware operation, including modules and ports, power Installation Guides supply, fans, transceivers, CPU interrupt errors, switch Management and Configuration Guide temperature, and so on. Chassis messages include events on Power Over Ethernet (POE) operation. Console interface used to monitor switch and port status, Installation and Getting Started Guide reconfigure the switch, read the event log through an in-band Telnet or out-of-band connection. C-25
