Configuring the Time and Date 41
3Com recommends that you set the time and date parameters before you
install certificates on the WX switch. Generally, certificates are valid for
one year beginning with the system time and date that are in effect when
you generate the certificate request. If the switch's time and date are
incorrect, the certificate might not be valid.
To configure time and date parameters, use the following commands:
set timezone zone-name {-hours [minutes]}
set summertime summer-name [start week weekday month hour min
end week weekday month hour min]
set timedate {date mmm dd yyyy [time hh:mm:ss]}
set ntp {enable | disable}
set ntp server ip-addr
To verify the changes, use the following commands:
display timezone
display summertime
display timedate
display ntp
The following commands configure the timezone as PST (Pacific Standard
Time) with an offset of -8 hours from UTC and enable the standard
summertime offset and name it PDT (Pacific Daylight Time). Additional
commands configure an NTP server and enable the WX switch's NTP
client.
WX1200# set timezone PST -8
success: change accepted.
WX1200# set summertime PDT
success: change accepted.
WX1200# set ntp server 192.168.1.10
WX1200# set ntp enable
success: NTP Client enabled
The following commands display time and date parameters and the
current time and date:
