18. Set the switch time to be closely synchronized with the system time (within 1 minute). Replace
MMDDhhmmYYYY with the actual system time:
ISR-9024(config)# exit
ISR-9024# clock set MMDDhhmmYYYY
For example, to set the system date and time to 2:42 p.m. on September 29, 2006, enter the following
command:
ISR-9024# clock set 092914422006
19. Reset the switch to save the settings you just made:
ISR-9024# reload
20. Log in as the root user on the head node.
21. Use the text editor of your choice to open the /etc/hosts file and add an entry for each switch. For
example, if you have one switch, the entry is similar to the following:
172.20.66.1 IR0N00
Use the number zero (0), not the letter O, in the host name IR0N00. Make the entries above the
following line in the file because any entries that follow this line will be deleted if you reconfigure
the system:
#XC-CLUSTER Do Not Edit Below this Line
22. Save your changes and exit the file.
23. Repeat this entire procedure for each switch controller card, modifying the host name and switch
address using the data in Table D-4 as a reference.
After completing this procedure, you can access the switch controller cards using either the switch name
or IP address:
# telnet IR0N00
When the connection is established, use the password you set in step 6 to log in to the switch controller.
