Basic Operation Guide 2014/02

System Name: Using a unique name helps you to identify individual devices where you are using
an SNMP network management tool such as HP PCM+.
System Contact and Location: This information is helpful for identifying the person administratively
responsible for the switch and for identifying the locations of individual switches.
MAC Age Time: The number of seconds a MAC address the switch has learned remains in the
switch’s address table before being aged out (deleted). Aging out occurs when there has been no
traffic from the device belonging to that MAC address for the configured interval.
Time Sync Method: Selects the method (TimeP or SNTP) the switch will use for time synchronization.
For more on this topic, see "Time Protocols" in the Management and Configuration Guide.
Time Zone: The number of minutes your time zone location is to the West (+) or East (-) of
Coordinated Universal Time (formerly GMT). The default 0 means no time zone is configured. For
example, the time zone for Berlin, Germany is + 60 (minutes) and the time zone for Vancouver,
Canada is - 480 (minutes).
Daylight Time Rule: Specifies the daylight savings time rule to apply for your location. The default
is None. (For more on this topic, See Appendix D, "Daylight Savings Time on HP switches.)
Time: Used in the CLI to specify the time of day, the date, and other system parameters.

To help distinguish one switch from another, configure a plain-language identity for the switch.
Syntax:
hostname <name-string>
snmp-server [contact <system-contact>] [location <system-location>]
Each field allows up to 255 characters. To help simplify administration, it is recommended that
you configure hostname to a character string that is meaningful within your system.
For example, to name the switch "Blue" with "Next-4474" as the system contact, and
"North-Data-Room" as the location:
