Note: Enterasys Networks recommends that you set the time and date parameters before you
install certificates on the RBT switch. If the switch’s time and date are incorrect, the certificate might
not be valid.
Generally, CA-generated certificates are valid for one year beginning with the system time and date
that are in effect when you generate the certificate request. Self-signed certificates generated when
running MSS Version 4.2.3 or later are valid for three years, beginning one week before the time
and date on the switch when the certificate is generated.
If you do not install certificates, the switch automatically generates them the first time you boot the
switch with MSS Version 4.2 or later. The automatically generated certificates are dated based on
the time and date information present on the switch when it was first booted with MSS Version 4.2.
Note: Configure summertime before you set the time and date. Otherwise, summertime’s
adjustment of the time will make the time incorrect, if the date is within the summertime period.
