Cisco Logging to RHEL

·111 words·1 min·

If you have a Cisco device logging to RHEL, here’s all that’s necessary:

# vi /etc/sysconfig/syslog

Check the facility listed in the Cisco configuration, and convert it into the linux syslog facility levels found on Cisco’s syslog configuration documentation:

For example, Cisco’s facility 19 is the same as linux’s facility 3.

# vi /etc/syslog.conf
*.info;mail.none;authpriv.none;cron.none;local3.none;   /var/log/messages
local3.*                                                /var/log/cisco.log

Add local3.none; to the /var/log/messages line and add the local3.* line at the bottom of the file.

Restart syslog with /etc/init.d/syslog restart. Verify that the syslog server is listening on port 514 and then tail your new /var/log/cisco.log:

# netstat -plan | grep 514
udp        0      0       *          3770/syslogd
