How To Configure Cisco's Syslog Logging

In this blog entry I will outline the steps you need to take on your Cisco Router or Catalyst device to configure syslog logging.

If you are configuring a Cisco Router for syslog logging then please follow the steps below:

1. In order to ensure that logging is enabled, issue the logging on command.

Router(config)# logging on

2. In order to specify the Essentials server that is to receive the router syslog messages, issue the logging ip_address command. ip_address is the address of the server that collects the syslog messages.

Router(config)# logging 1.1.1.1

3. In order to limit the types of messages that can be logged to the Essentials server, set the appropriate logging trap level with the logging trap informational command. The informational portion of the command signifies severity level 6. This means all messages from level 0-5 (from emergencies to notifications) are logged to the Essentials server.

Router(config)# logging trap informational

Valid logging facilities are local0 through local7.

Valid levels are:

emergency
alert
critical
error
warning
notification
informational
debug
4. In order to verify if the device sends syslog messages, run the sh logging command. You see all the syslog messages that are sent. If you do not see syslog messages, ensure that this is configured:

logging on logging console debug logging monitor debug logging trap debug

If you are configuring a Cisco Catalyst device for syslog logging please follow the steps below:

1. Ensure sure logging is enabled with the set logging server enable command.

Catalyst> (enable) set logging server enable

2. Specify the Essentials server that is to receive the router syslog messages, with the logging server_ip command. server ip is the IP address of the Essentials server.

Catalyst> (enable) set logging server 1.1.1.1

3. Limit the types of messages logged to the Essentials server. Enter set logging level informational, where informational signifies severity level 6. This means that all messages from level 0-5 (from emergencies to notifications) are logged to the Essentials server.

Catalyst> (enable) set logging server severity 6

4. In order to see if syslog messages are sent, use the sh logging buffer command. You see syslog messages that are sent. If you experience problems with switches, try this configuration:

set logging level all 7 default

set logging server enable

set logging server 1.1.1.1 (your unix syslog server ip address)

set logging server facility LOCAL7

set logging server severity 7 #syslog

set logging console enable

set logging server enable

set logging server 1.1.1.1

set logging level cdp 7 default

set logging level mcast 7 default

set logging level dtp 7 default

set logging level dvlan 7 default

set logging level earl 7 default

set logging level fddi 7 default

set logging level ip 7 default

set logging level pruning 7 default

set logging level snmp 7 default

set logging level spantree 7 default

set logging level sys 7 default

set logging level tac 7 default

set logging level tcp 7 default

set logging level telnet 7 default

set logging level tftp 7 default

set logging level vtp 7 default

set logging level vmps 7 default

set logging level kernel 7 default

set logging level filesys 7 default

set logging level drip 7 default

set logging level pagp 7 default

set logging level mgmt 7 default

set logging level mls 7 default

set logging level protfilt 7 default

set logging level security 7 default

set logging level radius 7 default

set logging level udld 7 default

set logging level gvrp 7 default

set logging server facility LOCAL7

!

Enter: sh logging

You see this output:

Logging buffer size: 500

timestamp option: enabled

Logging history size: 1

Logging console: enabled

Logging server: enabled {1.1.1.1}

server facility: LOCAL7

server severity: debugging(7)

Current Logging Session: enabled

Your Cisco device will now be configured for syslog logging.
