This chapter describes the utility commands available in the FASTPATH® CLI.
The commands in this chapter are presented in four groups:
- Show commands display switch settings, statistics, and other information.
- Configuration commands configure features and options of the switch. For every configuration command, there is a show command that displays the configuration setting.
- Copy commands transfer or save configuration and informational files to and from the switch.
- Clear commands clear some or all of the settings to factory defaults.
This chapter includes the following sections:
Dual Image Commands
FASTPATH software supports a dual image feature that allows the switch to have two FASTPATH images in the permanent storage. You can specify which image is the active image to be loaded in subsequent reboots. This feature allows reduced down-time when you upgrade or downgrade the FASTPATH software.
delete
This command deletes the supplied image file from the permanent storage. The image to be deleted must be a backup image. If this image is the active image, or if this image is activated, error is displayed.

boot system
This command activates the specified image. It will be the active-image for subsequent reboots and will be to be loaded by the boot loader. The current active-image is marked as the backup-image, for subsequent reboots. If the specified image doesn’t exist on the system, this command returns error.

System Utility and Clear Commands
This section describes the commands you use to help troubleshoot connectivity issues and to restore various configurations to their factory defaults.
traceroute
Use the traceroute command to discover the routes that packets actually take when traveling to their destination through the network on a hop-by-hop basis. The <ipaddr> value should be a valid IP address. The [<port>] value should be a valid decimal integer in the range of 0 (zero) to 65535. The optional port parameter is the UDP port used as the destination of packets sent as part of the traceroute. This port should be an unused port on the destination system. The default value is 33434.

client-identifier
This command specifies the unique identifier for a DHCP client. Unique-identifier is a valid notation in hexadecimal format. In some systems, such as Microsoft DHCP clients, the client identifier is required instead of hardware addresses. The unique-identifier is a concatenation of the media type and the MAC address. For example, the Microsoft client identifier for Ethernet address c819.2488.f177 is 01c8.1924.88f1.77 where 01 represents the Ethernet media type. For more information, refer to the “Address Resolution Protocol Parameters” section of RFC 1700, Assigned Numbers for a list of media type codes.

DHCP Filtering
You can configure the DHCP Filtering feature as a security measure against unauthorized DHCP servers. DHCP filtering works by allowing you to configure each port as either a trusted port or an untrusted port. To optimize the DHCP filtering feature, configure the port that is connected to an authorized DHCP server on your network as a trusted port. Any DHCP responses received on a trusted port are forwarded. Make sure that all other ports are untrusted so that any DHCP (or BootP) responses received are discarded.
You can configure DHCP filtering on physical ports and LAGs. DHCP filtering is not operable on VLAN interfaces.
