You should avoid using PCs that have IP addresses randomly assigned to them by DHCP. The switch
Note
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.

Implementing Syslog with the CLI

To configure a syslog server using the CLI, follow these steps:
Configure the Cisco MDS switch:
Step 1
switch1# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch1(config)# logging server 172.22.36.211 6 facility local1
To display the configuration:
switch1# show logging server
Logging server: enabled
{172.22.36.211}
Step 2 Configure the syslog server:
Test the syslog server by creating an event on the Cisco MDS switch . In this case, port fc1/2 was
Step 3
bounced and the following was listed on the syslog server. Notice that the IP address of the switch is
listed in brackets.

a. Modify /etc/syslog.conf to handle local1 messages. For Solaris, there needs to be at least one
tab between the facility.severity and the action (/var/adm/MDS_logs).
#Below is for the MDS 9000 logging
