> # System Message Logging Servers

> Device Manager allows you to view event logs on your local PC as well as those on the switch. For a permanent record of all events that occur on the switch, you should store these messages off the switch. To do this the Cisco MDS 9000 Family switch must be configured to send syslog messages to your local PC and a syslog server must be running on that PC to receive those messages. These messages can be categorized into four classes:

> - Hardware—Line card or power supply problems
> - Link Incidents—FICON port condition changes
> - Accounting—User change events
> - Events—All other events

> Note You should avoid using PCs that have IP addresses randomly assigned to them by DHCP. The switch continues to use the old IP address unless you manually change it; however, the Device Manager prompts you if it does detect this situation. UNIX workstations have a built-in syslog server. You must have root access (or run the Cisco syslog server as setuid to root) to stop the built-in syslog daemon and start the Cisco syslog server.
