System information

System information features:

Feature		Default
System Name		switch product name
System Contact		N/A
System Location		N/A
MAC Age Time		300 seconds
Time Sync Method		None
Time Zone		0
Daylight Time Rule		None
Time		January 1, 1990 at 00:00:00 at last power reset

Configuring system information is optional, but recommended.

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 the "Time Protocols" chapter in the latest 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.

Viewing and configuring system information

Listing the current system information. The following command lists the current system information settings:

This example shows the switch’s default console configuration.

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:

System information listing after executing the preceding commands

Reconfigure the MAC age time for learned MAC addresses. This command corresponds to the MAC Age Interval in the menu interface, and is expressed in seconds.

Syntax

mac-age-time <10-1000000>

(seconds)

Allows you to set the MAC address table’s age-out interval. An address is aged out if the switch does not receive traffic from that MAC address for the age-out interval, measured in seconds. Default: 300 seconds.

For example, to configure the age time to seven minutes:

HP Switch(config)# mac-age-time 420

Configure the time zone and daylight time rule. These commands:

Set the time zone you want to use
Define the daylight time rule for keeping the correct time when daylight-saving-time shifts occur.

Syntax

time timezone <-720 - 840> time daylight-time-rule <none | alaska | continental-us-and-canada | middle-europe-and-portugal | southern-hemisphere | western-europe | user-defined>

East of the 0 meridian, the sign is "+". West of the 0 meridian, the sign is "-".

For example, the time zone setting for Berlin, Germany is +60 (zone +1, or 60 minutes), and the time zone setting for Vancouver, Canada is -480 (zone -8, or -480 minutes). To configure the time zone and daylight time rule for Vancouver, Canada:

HP Switch(config)# time timezone -480 daylight-time-rule
continental-us-and-canada

Configure the time and date. The switch uses the time command to configure both the time of day and the date. Also, executing time without parameters lists the switch’s time of day and date. Note that the CLI uses a 24-hour clock scheme; that is, hour (hh) values from 1 p.m. to midnight are input as 13 - 24, respectively.

Syntax

time [hh:mm [:ss]] [mm/dd/ [yy] yy ]

For example, to set the switch to 9:45 a.m. on November 17, 2012:

HP Switch(config)# time 9:45 11/17/12


	NOTE: Executing reload or boot resets the time and date to their default startup values.
