When Daylight Savings Time (DST) is enabled, the switch clock will automatically set the default DST parameters for the time zone specified on the switch or for the custom parameters you can specify with the system daylight savings time command. In this case, it is not necessary to change the time setting on the switch when your time zone changes to and from DST. To verify the DST parameters for your switch, use the system daylight savings time command. A screen similar to the following will be displayed:
-> system daylight savings time
Daylight Savings Time (DST) is DISABLED. PST: (Coordinated Universal Time) UTC-8 hours Daylight Savings Time (DST):
DST begins on the first sunday in april (4/7) at 2:00 DST ends on the last sunday in october (10/27) at 2:00 DST will change the time by +/- 1:00 hour(s)
The second line in the above display indicates the Enabled/Disabled status of the DST setting on the switch. The last three lines describe the date and time parameters for the selected time zone or the custom parameters set with the CLI. To enable daylight savings time use the following command:
-> system daylight savings time enable
Note. If your time zone shows “No default” in the “Time Zone and DST Information Table”, refer to “Daylight Savings Time Configuration” on page 1-41 for information on configuring and enabling DST.

2 Logging Into the Switch
Logging into the switch may be done locally or remotely. Management tools include: the Command Line Interface (CLI), which may be accessed locally through the console port, or remotely through Telnet; WebView, which requires an HTTP client (browser) on a remote workstation; and SNMP, which requires an SNMP manager (such as Alcatel-Lucent OmniVista or HP OpenView) on the remote workstation. Secure sessions are available using the Secure Shell interface; file transfers are done through FTP or Secure Shell FTP.
In This Chapter
This chapter describes the basics of logging into the switch to manage the switch through the CLI. It also includes the information about using Telnet, FTP, and Secure Shell in both IPv4 and IPv6 environments for logging into the switch as well as information about using the switch to start a Telnet or Secure Shell session on another device. It also includes information about managing sessions and specifying a DNS resolver. For more details about the syntax of referenced commands, see the OmniSwitch 6250/6450 CLI Reference Guide.
Configuration procedures described in this chapter include: • “Quick Steps for Logging Into the Switch” on page 2-5 • “Using Telnet” on page 2-8
• “Using FTP” on page 2-10
• “Using Secure Shell” on page 2-12
• “Modifying the Login Banner” on page 2-21 • “Configuring Login Parameters” on page 2-23 • “Enabling the DNS Resolver” on page 2-24
Management access is disabled (except through the console port) unless specifically enabled by a network administrator. For more information about management access and methods, use the table here as a guide:
