Configuring Time
Configuring Time Zones Settings
Use the time-zone-settings command to configure the time zone settings on the sensor, such as the time
zone name the sensor displays whenever summertime settings are not in effect and the offset.
To configure the time zone settings on the sensor, follow these steps:
Step 1 Log in to the sensor using an account with administrator privileges.
Step 2 Enter time zone settings submode.
sensor# configure terminal
sensor(config)# service host
sensor(config-hos)# time-zone-settings
Step 3 Configure the time zone name that is displayed whenever summertime settings are not in effect. The
default is UTC.
sensor(config-hos-tim)# standard-time-zone-name CST
Step 4 Configure the offset in minutes. The offset is the number of minutes you add to UTC to get the local
time. The default is 0.
sensor(config-hos-tim)# offset -360
Step 5 Verify your settings.
sensor(config-hos-tim)# show settings
time-zone-settings
-----------------------------------------------
offset: -360 minutes default: 0
standard-time-zone-name: CST default: UTC
-----------------------------------------------
sensor(config-hos-tim)#
Step 6 Exit time zone settings submode.
sensor(config-hos-tim)# exit
sensor(config-hos)# exit

Step 7 Press Enter to apply the changes or enter no to discard them.
Configuring NTP
This section describes how to configure a Cisco router to be an NTP server and how to configure the
sensor to use an NTP server as its time source. It contains the following topics:
• Configuring a Cisco Router to be an NTP Server, page 4-41
• Configuring the Sensor to Use an NTP Time Source, page 4-43
Configuring a Cisco Router to be an NTP Server
The sensor requires an authenticated connection with an NTP server if it is going to use the NTP server
as its time source. The sensor supports only the MD5 hash algorithm for key encryption. Use the
following procedure to activate a Cisco router to act as an NTP server and use its internal clock as the
time source.
