Providing Credentials for Devices

Contents

Overview

Once you add the device to the DeviceExpert inventory, you need to provide device credentials to establish communication between the device and DeviceExpert. Details such as the mode (protocol) through which communication is to be established, port details, login name, password etc. are to be provided.

Guidelines on choosing credentials for a Single Device

To establish credentials for a single device,

 

    1. Go to "Inventory" and select the device for which communication has to be established

    2. click 'Credentials' menu on the top bar

 

In the Credentials UI, provide the following details:

Choosing the Protocol

Based on the type of device, you can select any of the following combinations of protocols to establish communication between DeviceExpert and the device:

 

    1. TELNET-TFTP (Establishing communication with the device via Telnet and transferring the configuration via TFTP)

    2. TELNET (Establishing communication with the device via TELNET and executing show commands on the device to get configuration details)

    3. SSH-TFTP (Establishing communication with the device via SSH and transferring the configuration via TFTP)

    4. SSH-SCP (Establishing communication with the device via SSH and transferring the configuration via SCP)

    5. SSH (Establishing communication with the device via SSH and executing show commands on the device to get configuration details)

    6. SNMP-TFTP (Establishing communication with the device via SNMP and transferring the configuration via TFTP)

 

Based on the protocol choice, you need to provide other credentials.

For TELNET-TFTP, TELNET, SSH-TFTP, SSH-SCP & SSH

User Credential Profile

If you have downloaded DeviceExpert and carrying out the settings for the first time, you may skip this 'User Credential Profile' step.

 

DeviceExpert offers the flexibility of creating common credentials and sharing the common credentials among multiple devices. The Common Credentials are known as profiles. For more details click here.

Credentials for TELNET-TFTP, TELNET, SSH-TFTP, SSH-SCP & SSH

The following screenshots depict how to enter the credentials for the devices. For ease of understanding, the screenshots illustrate how the credentials are entered while accessing the device via a telnet console and explain how the same values are entered in the DeviceExpert GUI.

 

Credentials have been split into two divisions:

 

 

 

Important Note: Refer to the explanatory screenshots below before proceeding with entering the credentials.

Primary Credentials 

S.No

Credential

Description

1

Login Name

While establishing connection with a device, if the device asks for a Login Name, set a value for this parameter. This parameter is Optional.

2

Password

To set the Password for accessing the device.

3

Prompt

The prompt that appears after successful login.

4

Enable UserName

When entering into privileged mode, some devices require UserName to be entered. Provide the username if prompted; otherwise leave this field empty.

5

Enable Password

This is for entering into privileged mode to perform configuration operations like backup/upload. This parameter is mandatory.

6

Enable Prompt

This is the prompt that will appear after going into enable mode.

 

Additional Credentials

Click the link "Additional Credentials" to view/enter values for these parameters. Except TFTP/SCP Server Public IP, all other parameters are usually assigned with certain Standard Values by default. Such standard values have been filled for these parameters. Most of the devices would work well with these values and you need not edit these details unless you want to provide different set of details.

 

S.No

Credential

Description

1

TFTP / SCP Server Public IP

When the device is present outside the private network (i.e. when the private IP of DeviceExpert is not reachable for the device) this parameter can be used to provide the public IP of the DeviceExpert server (NAT'ed IP of DeviceExpert). This IP will be used in Configuration backup via TFTP / SCP.

2

Telnet/SSH Port

Port number of Telnet/SSH - 23 (for Telnet) and 22 (for SSH) by default.

3

Login Prompt

The text/symbol that appears on the console to get the typed login name is referred as login prompt. For example, Login:
 

4

Password Prompt

The text displayed on the console when asking for password. For example, Password:

5

Enable User Prompt

The text displayed on the console when asking for Enable UserName. For example, UserName:

6

Enable Password Prompt

The text displayed on the console when asking for password. For example, Password:

 

 

 

Once you complete this step - that is, providing credentials, you will find the credentials icon beside the device name in the inventory.

 

 

For SNMP-TFTP

User Credential Profile

If you have downloaded DeviceExpert and carrying out the settings for the first time, you may skip this 'User Credential Profile' step.

 

DeviceExpert offers the flexibility of creating common credentials and sharing the common credentials among multiple devices. The Common Credentials are known as profiles. For more details click here.

Primary Credentials for SNMP-TFTP

 

S.No

Credential

Description

1

SNMP Port

Port number of SNMP - 161 by default.

2

Read Community

An SNMP community is a group of managed devices and network management systems within the same administrative domain. Each SNMP request packet includes a community name. When a request packet is received, the remote access server looks for the name in its community table:
 

  • If the name is not found, the request is denied and an error is returned.

  • If the name is found, the associated access level is checked and the request is accepted if the access level is high enough for the request.

 

The SNMP Read Community string is like a user id or password that allows Read-only access to the device.

3

Write Community

The SNMP Write Community string is like a user id or password that allows Read and Write access to the devices.

 

Additional Credentials

Click the link "Additional Credentials" to view/enter values for these parameters. Except TFTP/ SCP Server Public IP, all other parameters are usually assigned with certain Standard Values by default. Such standard values have been filled for these parameters. Most of the devices would work well with these values and you need not edit these details unless you want to provide different set of details.

 

S.No

Credential

Description

1

TFTP / SCP Server Public IP

When the device is present outside the LAN (i.e. when the private IP of DeviceExpert is not reachable for the device) this parameter can be used to provide the public IP of the DeviceExpert server (NAT'ed IP of DeviceExpert). This IP will be used in Configuration backup via TFTP.

Testing the Validity of Credentials

Credential values entered through the Credentials GUI should be accurate. Otherwise, DeviceExpert will not be able to establish connection with the device. To ensure the correctness of credential values, DeviceExpert provides the testing option. After entering the credentials, you can test the values during which DeviceExpert will indicate if the values entered are valid. It will pinpoint the invalid values and you can carryout corrections accordingly.

To test the validity of credentials,

 

 

 

 

 

 

Note: The credential testing option is provided only for TELNET-TFTP, TELNET, SSH and SSH-TFTP protocols.

 

Sharing Common Credentials Across Devices

In practical applications, you may find that the same set of credentials could well be applied 'as they are' to many devices. In such cases, to avoid the cumbersome task of entering the credentials for each device separately, DeviceExpert offers the flexibility of creating common credentials and sharing the common credentials among multiple devices. This is called as 'Credential Profile'.

 

Credential Profile can be created as a ready-to-use format called simply as 'Profiles'. You can create a profile with a specific name. Once you create a credential profile, its name will automatically be listed in the drop-down menu in the "Credentials" UI for the field "Use Profile". When you wish to use the profile, if you just choose the corresponding profile in the drop-down menu, all the credential information will be automatically filled-up.

Creating Credential Profiles

To create Credential Profiles,

Managing Credential Profiles

Go to "Admin" >> "Device Management" >> "Credential Profile" to edit/remove a profile or to view the devices referred by a profile.
