Configure Cisco router to send syslog messages to syslog server

I needed to configure some Cisco routers to send syslog messages to a syslog server; here is how I did it.

Two things to note;

1. is the IP address of the syslog server you are sending the messages to.

2. I was not receiving messages from the remote routers; after some troubleshooting I discovered I needed to tell the remote routers what interface to send the message out on. In my case is was BVI1.

A quick way to test connectivity from the router is with the ping command specifying the source interface.

router#ping source BVI1

Here are the configuration steps

router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#service sequence-numbers
router(config)#service timestamps debug datetime localtime show-timezone
router(config)#service timestamps log datetime localtime show-timezone msec
router(config)#logging facility local3
router(config)#logging trap informational
router(config)#logging buffered 1000000
router(config)#no logging console
router(config)#no logging monitor
router(config)#default logging rate-limit
router(config)#default logging queue-limit
router(config)#logging source-interface BVI1
router#sh logging
