How to setup syslog server on Linux to receive log messages from Cisco Devices

1. Setup your Cisco devices to send Cisco log to your syslog server

logging 1.2.3.4 ! where 1.2.3.4 is your Cisco log server

logging trap debug

logging on 

2. Make sure rsyslog daemon is installed on your host.  I'm using rsyslog-2.0.2-3.fc8.

3. Tell the syslog daemon to listen for messages from remote devices

vi /etc/sysconfig/rsyslog

SYSLOGD_OPTIONS="-m0 -r" 

4. Tell the rsyslog daemon to write the messages to cisco.log

vi /etc/rsyslog.conf

local7.debug    /var/log/cisco.log
