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-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.

802.1x 802.1X authentication: Provides access control on a per-client
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
Access Security Guide
addrmgr Address Table Manager: Manages MAC addresses that the
switch has learned and are stored in the switch’s address
table.
Management and Configuration Guide
auth Authorization: A connected client must receive authorization
through web, AMC, RADIUS-based, TACACS+-based, or
802.1X authentication before it can send traffic to the switch.
Access Security Guide
cdp Cisco Discovery Protocol: Supports reading CDP packets
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.
Management and Configuration Guide
chassis Hardware operation, including modules and ports, power
supply, fans, transceivers, CPU interrupt errors, switch
temperature, and so on. Chassis messages include events on
Power Over Ethernet (POE) operation.
Installation Guides
Management and Configuration Guide
console Console interface used to monitor switch and port status,
reconfigure the switch, read the event log through an in-band
Telnet or out-of-band connection.
