Chapter 2 System Message Overview

How to Read System Messages

All syslog messages generated by a Catalyst 3750 and 2975 switch other than the master switch are

displayed ending with (Switch-x) where Switch-x is the number of the stack member generating the

message. Syslog messages generated by the master switch are displayed with no hostname string.

This example shows a partial switch system message on a switch other than a Catalyst 3750 and

2975 switch:

00:00:46: %LINK-3-UPDOWN: Interface Port-channel1, changed state to up

00:00:47: %LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to up

00:00:47: %LINK-3-UPDOWN: Interface GigabitEthernet0/2, changed state to up

00:00:48: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to down

00:00:48: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/1, changed

state to down 2 *Mar 1 18:46:11: %SYS-5-CONFIG_I: Configured from console by vty2

(10.34.195.36)

18:47:02: %SYS-5-CONFIG_I: Configured from console by vty2 (10.34.195.36)

*Mar 1 18:48:50.483 UTC: %SYS-5-CONFIG_I: Configured from console by vty2 (10.34.195.36)

This example shows a partial switch system message for a stack master and a stack member switch

(hostname Switch-2) in a Catalyst 3750 switch stack or a Catalyst 2975 switch stack:

00:00:46: %LINK-3-UPDOWN: Interface Port-channel1, changed state to up

00:00:47: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to up

00:00:47: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/2, changed state to up

00:00:48: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to down

00:00:48: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/1, changed

state to down 2

00:00:47: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/2, changed state to up (Switch-2)

(Switch-2)

00:00:48: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/1, changed

state to down 2 (Switch-2)
