System Messages
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.
Implementing Syslog with the CLI
To configure a syslog server using the CLI, follow these steps:
Step 1
Configure the Cisco MDS switch:
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}
server severity: notifications
server facility: local1
Step 2
Configure the syslog server:
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
local1.notice /var/adm/MDS_logs
b.
Create the log file.
#
touch /var/adm/MDS_logs
c.
Restart syslog.
#
/etc/init.d/syslog stop
#
/etc/init.d/syslog start
syslog service starting.
d.
Verify syslog started.
#
ps -ef |grep syslogd
root 23508 1 0 11:01:41 ? 0:00 /usr/sbin/syslogd
Step 3
Test the syslog server by creating an event on the Cisco MDS switch . In this case, port fc1/2 was
bounced and the following was listed on the syslog server. Notice that the IP address of the switch is
listed in brackets.
#
