Command Syntax and Usage

ntp

Displays the Network Time Protocol (NTP) Server Menu.

To view menu options, see page 186.

ssnmp

Displays the System SNMP Menu. To view menu options, see page 188.

access

Displays the System Access Menu. To view menu options, see page 201.

date

Prompts the user for the system date. The date reverts to its default value when the switch is reset.

time

Configures the system time using a 24-hour clock format. The time reverts to its default value when the switch is reset.

timezone

Configures the time zone where the switch resides. You are prompted to select your location (con- tinent, country, region) by the timezone wizard. Once a region is selected, the switch updates the time to reflect local changes to Daylight Savings Time, etc.

olddst enabledisable

Enables or disables use of the Daylight Saving Time (DST) rules in effect prior to the year 2007. The default value is disabled.

idle <idle timeout in minutes>

Sets the idle timeout for CLI sessions, from 1 to 60 minutes. The default is 5 minutes.

notice <max 1024 char multi-line login notice> <'-'to end>

Displays login notice immediately before the “Enter password:” prompt. This notice can contain up to 1024 characters and new lines.

e2e enabledisable

Enables or disables End-to-End flow control mode. The default value is enabled. If you change the flow-control mode, you must apply and save the changes, then reboot the switch before the change takes effect.

The GbE switch module has two switching chips connected by an internal high-capacity link (Higig). Over subscription of traffic across the Higig link is handled by one of the following flow control modes:

„End-to-End (E2E) Flow Control

„Ingress Back Pressure (IBP) across the Higig link

One of the modes should be enabled, and the other mode disabled. E2E flow control works best for most applications. E2E provides a higher throughput and better overall switch performance, but does not provide lossless flow control.
