Maintenance Commands

Maintenance Commands

Introduction

The Maintenance commands are used for debugging purposes, enabling you to generate a technical support dump of the critical state information in the switch, and to clear entries in the Forwarding Database and the Address Resolution Protocol (ARP) and routing tables. These commands are available only from an administrator login.

Dump information contains internal switch state data that is written to flash memory on the switch after any one of the following occurs:

•The switch administrator forces a switch panic. The panic option causes the switch to dump state information to flash memory, and then causes the switch to reboot.

•The switch administrator enters the switch reset key combination (Ctrl-Shift-6) on a device that is attached to the console port.

•The switch detects a hardware or software problem that requires a reboot.

The following sections provide detailed information and commands.

System maintenance

The System Maintenance commands are reserved for use by HP technical support. The options are used to perform system debugging.

The following table describes the System Maintenance commands. Table 180 System Maintenance commands
