To turn off the LEDs on all ports on a device, use the disable ports leds Global Configuration mode command.

To set the LEDs of all the ports on the device to their current operational status of the port, use the no disable ports leds command.

Syntax

disable ports leds

no disable ports leds

Parameters

This command has no arguments or keywords.

Default Configuration

The default is no disable port leds; that is the LEDs of all the ports reflect their current status.

Command Mode

Global Configuration mode

Examples

The following example turns off the port LEDs.

switchxxxxxx(config)# disable ports leds

To specify or modify the device host name, use the hostname Global Configuration mode command. To remove the existing host name, use the no form of the command.

Syntax

hostname name

no hostname

Parameters

Name—Specifies the device host name. (Length: 1-58 characters). The hostname must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphens.

Default Configuration

No host name is defined.

Command Mode

Example

The following example specifies the device host name as ‘enterprise’.

switchxxxxxx(config)# hostname enterprise
enterprise(config)#

To reload the operating system at a user-specified time, use the reload Privileged EXEC mode command.

Syntax

reload [in [hhh:mm | mmm] | at hh:mm [day month]] | cancel]

Parameters

• in hhh:mm | mmm—(Optional) Schedules a reload of the software to take effect in the specified minutes or hours and minutes. The reload must take place within approximately 24 days.

• at hh:mm—(Optional) Schedules a reload of the software to take place at the specified time (using a 24-hour clock). If you specify the month and day, the reload is scheduled to take place at the specified time and date. If you do not specify the month and day, the reload takes place at the specified time on the current day (if the specified time is later than the current time) or on the next day (if the specified time is earlier than the current time). Specifying 00:00 schedules the reload for midnight. The reload must take place within 24 days.

• day—(Optional) Number of the day in the range from 1 to 31.

• month—(Optional) Month of the year.

• cancel—(Optional) Cancels a scheduled reload.

Default Usage

None

Command Mode

Privileged EXEC mode

User Guidelines

The at keyword can be used only if the system clock has been set on the device. To schedule reloads across several devices to occur simultaneously, synchronize the time on each device with SNTP.

When you specify the reload time using the at keyword, if you specify the month and day, the reload takes place at the specified time and date. If you do not specify the month and day, the reload takes place at the specified time on the current day (if the specified time is later than the current time), or on the next day (if the specified time is earlier than the current time). Specifying 00:00 schedules the reload for midnight. The reload must take place within 24 days.

To display information about a scheduled reload, use the show reload command.

To display environment information, use the show environment User EXEC mode command.

Syntax

show environment {all | fan | temperature {status} | stack [switch-number]}

Parameters

• all—Displays the fan and temperature general status. If this parameter is used - a fault situation will be reported if it exists on any one of the stack units

• fan—Displays the fan(s) status

• temperature {status}—Displays the temperature status

• stack [switch-number]—(Optional) Displays detailed environment status of a stack, per each stack unit. If the switch-number is specified, the environment status of the selected device number is displayed. (Range: 1 – 4)

Command Mode

User EXEC mode

User Guidelines

The fan and temperature status parameters are available only on devices on which fan and/or temperature sensor are installed.

Fan status can be one of:

• OK - The fan/s functions correctly.

• Failure - One or more of the fans failed.

• Fan read fail - Reading information from one or more fans failed.

• NA - No fan is installed.

Temperature can be one of:

• OK - The temperature is below the warning threshold.

• Warning- The temperature is between the warning threshold and the critical threshold.

• Critical - the temperature is above the critical threshold.

Use the show platform certificate Privileged EXEC mode command to display the device SUDI certificate and optionally a signature over the certificate.

Syntax

show platform sudi certificate [sign [nonce <nonce value>]]

Parameters

• sign—(Optional) display a signature over the certificate

• [nonce <nonce value>]—(Optional) provide a nonce to use with the signature to protect from replay attacks. (range 0-4,294,967,295)

Default Usage

The certificate is displayed without a signature. If the sign parameter is specified without a nonce value then the signature will be generated without using a nonce.

Command Mode

Privileged EXEC mode

User Guidelines

show platform sudi certificate command displays the SUDI certificate. The command output includes the certificate chain in PEM format, where the first certificate that is displayed is the Cisco Root CA, and the second certificate that is displayed is the Cisco Subordinate/Intermediary Certificate. Both certificates can be verified to match the certificates published on https://www.cisco.com/security/pki/. The third certificate is the SUDI leaf certificate.

If the optional sign parameter is used, then the command output will display a signature over the certificates using the SUDI private key.

The command also supports an optional [nonce <nonce value>] parameter used as part of the signature inputs to prevent replay attacks. If the [nonce <nonce value>] parameter is not provided the signed data will not include the nonce.

The command output includes a signature version. The Signature value is set to 1 to indicate that the SUDI private key was used for signing.

Examples

Example 1: The following example displays the SUDI certificate chain without a signature:

switchxxxxxx# show platform sudi certificate
