Event Log entries

As shown in Format of an event log entry, each Event Log entry is composed of six or seven fields, depending on whether numbering is turned on or not:

Format of an event log entry
Item Description

Severity

One of the following codes (from highest to lowest severity):

M—(major) indicates that a fatal switch error has occurred.

E—(error) indicates that an error condition occurred on the switch.

W—(warning) indicates that a switch service has behaved unexpectedly.I—(information) provides information on normal switch operation.

D—(debug) is reserved for internal diagnostic information.

Date

The date in the format mm/dd/yy when an entry is recorded in the log.

Time

The time in the format hh:mm:ss when an entry is recorded in the log.

Event number

The number assigned to an event. You can turn event numbering on and off with the [no] log-number command.

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

macauth

Web and MAC authentication: Port-based security employed 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

Access Security Guide

maclock

MAC lockdown and MAC lockout
  • MAC lockdown prevents station movement and MAC address "hijacking" by requiring a MAC address to be used only on 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.
