Zero Touch Provisioning Overview

The Zero Touch Provisioning (ZTP) feature enables automatic provisioning of a switch connected to a network. ZTP automatically downloads and installs the image and configuration file in the device and aids in rapid deployment of devices in network with updated Firmware / Image version.

The ZTP feature uses the DHCPv4 protocol for assigning IP addresses to the switch.

These articles describe the ZTP module configuration on an Accedian switch. These articles describe the configuration details through CLI (Command Line Interface) and SNMP (Simple Network Management Protocol).

The reader is expected to have a basic knowledge of ZTP protocol as a prerequisite.

Acronyms

The following table lists the acronyms used in Zero Touch Provisioning and their expansion. This is fundamental to the information in these following articles.

General Configurations

The ZTP is configurable and managed by CLI and SNMP interfaces. This article provides the various modes for the CLI configuration and the various operations for the SNMP configuration.

Command Line Interface

Zero Touch Provisioning (ZTP) feature enables automatic provisioning of a switch connected to a network. The ZTP feature aids in rapid deployment of devices in network. The ZTP feature uses DHCPv4 protocol for acquiring the IP address for the switch device. Once the IP address is assigned to the switch, the switch will advertise the acquired IP address via advertisement frame and hence the switch will be remotely managed via acquired IP address.

ZTP commands are categorized as follows:

• Configuration Commands
  set beacon domain-id-value
  set beacon domain-id-match
  set use-beacon-rate
  set beacon advertisement
  set beacon advertisement interval
  set beacon discovery
• Display Command
  show ztp globals
• Debug Command
  debug ztp

CLI Command Modes

This section describes the various command modes available in the CLI configuration for ZTP, lists the command modes, access and exit methods of the modes, and the prompt displayed in the modes.

The following table lists the access and exit methods to various general configuration modes.

Basic SNMP Configurations

This section describes the Set, Get and Walk operations of the SNMP and also the details regarding the SNMP Manager. The following table lists the details regarding the manager used for SNMP configurations.

SNMP Configurations

SNMP Operations

The SNMP operations are used for loading MIB files, configuring values, and displaying the configured values. The syntaxes and examples of the SNMP operation are explained.

MIB Load

The MIB Load operation is used to register the MIB files with the SNMP manager.

1. Execute Scotty
   root@localhost mibs# scotty2.1.10
   %

2. Load the MIB files, so that the SNMP manager can learn about new MIB objects, such as their names, OIDs (Object Identifiers), and datatype.
   Syntax: mib load fsaccztp.mib

3. Create an SNMP session with switch vlan1 IP address as target agent IP, community as NETMAN, retries to be used in the requests as 0, the protocol version to be used as SNMPv2C, and timeout between retries as 30 seconds.
   

   ---

   Note: The SNMP session should be created for performing SNMP Get, Set and Walk operations in the particular SNMP session.

   ---

   
   % snmp session -address 12.0.0.1 -community "NETMAN" -retries 0 -version SNMPv2C -timeout 30
   snmp0

The following table lists the MIB files that must be loaded in the SNMP manager before issuing any Get / Set / Walk operation.

MIB Files

Set Operation

The Set operation is used to configure a particular value of an object identified by the indices used in the operation.

Syntax:
% snmpSession set {{ObjectName .Index1.Index2…IndexN DataType ValueToBeSet }}
Where:

A session represents the SNMP session identifier.
ObjectName represents the name of the object to be configured.
Index1.Index2……IndexN represents the indices of the object.
DataType represents the type of value to be stored in the object. DataType is an optional argument.
ValueToBeSet represents the value to be assigned for the object.

Output:
{ObjectIdentifier DataType Value}

Example: To start the ZTP module
% snmp0 set {{ fsaccztpBeaconconAdvInterval.0 600}}
Where:

Value to be set = start.
SNMP session identifier = 0.
The output is:
{1.3.6.1.4.1.2076.81.101.1.3.0 Unsigned32 600}

Get Operation

The Get operation is used to obtain the configured value of an object identified by the indices used in the operation.

Syntax:
% snmp Session get {{ObjectName .Index1.Index2…IndexN}}

Where:

Session represents the SNMP session identifier.
ObjectName represents the name of the object whose configuration is to be obtained.
Index1.Index2……IndexN represents the indices of the object.

Output:
{ObjectIdentifier DataType Value}

Example:
To get the value of the ZTP system status
% snmp0 get {{ fsaccztpBeaconconAdvInterval.0}}

Where:

SNMP session identifier = 0.
The output is:
{1.3.6.1.4.1.2076.81.101.1.3.0 Unsigned32 600}

Walk Operation

The snmpwalk command is designed to perform a sequence of chained GETNEXT requests. The command takes a single OID and displays a list of all results which lie within the subtree rooted on this OID.

Syntax:
% snmpSession walk ObjectTable.Name {puts $Object}

Where:

Session represents the SNMP session identifier.
Object represents a variable to which the output to be displayed is redirected.
Table Name represents the name of table from which configuration is to be obtained.

Output: {ObjectIdentifier DataType Value}

Example: To view the ZTP Context entry
% snmp0 walk x fsacczerotouchprovisioning {puts $x}
