Credentials and Profiles

1. Expand the Menu and select Manage switches.

2. On the Access Profiles card, select Add profile.

3. Enter a name for the profile, then select the authentication method you want to use: SSH or Basic

SSH

You must have sudoer permission to configure switches when using the SSH key method.

4. Create a pair of SSH private and public keys:

   ssh-keygen -t rsa -C "<USER>"
   

5. Copy the SSH public key to each switch that you want to upgrade using one of the following methods:

   • Manually copy the SSH public key to the /home/<USER>/.ssh/authorized_keys file on each switch, or
   • Run ssh-copy-id USER@<switch_ip> on the server where you generated the SSH key pair for each switch

6. Copy the SSH private key into the entry field:

For security, your private key is stored in an encrypted format, and only provided to internal processes while encrypted.

7. (Optional) To verify that the new profile is listed among available profiles, select View profiles from the Access Profiles card.

Basic Authentication

Be sure to use credentials for an account that has permission to configure switches.

The default credentials for Cumulus Linux have changed from cumulus/CumulusLinux! to cumulus/cumulus for releases 4.2 and later. For details, read Cumulus Linux User Accounts.

4. Enter a username and password.

5. Click Create, then confirm.

6. (Optional) To verify that the new profile is listed among available profiles, select View profiles from the Access Profiles card.

To configure basic authentication, run:

cumulus@switch:~$ netq lcm add credentials profile_name NEWPROFILE username cumulus password cumulus

Specify a unique name for the configuration after profile_name.

To configure SSH authentication using a public/private key:

1. If the keys do not yet exist, create a pair of SSH private and public keys.

   ssh-keygen -t rsa -C "<USER>"
   

2. Copy the SSH public key to each switch that you want to upgrade using one of the following methods:

   • Manually copy the SSH public key to the /home/<USER>/.ssh/authorized_keys file on each switch, or
   • Run ssh-copy-id USER@<switch_ip> on the server where you generated the SSH key pair for each switch

3. Add these credentials to the switch. Specify a unique name for the configuration after profile_name.

   cumulus@switch:~$ netq lcm add credentials profile_name NEWPROFILE ssh-key PUBLIC_SSH_KEY
   

1. Open the LCM dashboard.

2. On the Access Profiles card, select View profiles.

3. Select the checkbox next to the profile you’d like to edit. Then select Edit above the table.

4. Make your edits, then click Update.

The syntax for editing access profiles is:

cumulus@switch:~$ netq lcm edit credentials 
    profile_id <text-switch-profile-id> 
    [profile_name <text-switch-profile-name>] 
    [auth-type <text-switch-auth-type>] 
    [username <text-switch-username>] 
    [password <text-switch-password> | ssh-key <text-ssh-key>]

Run netq lcm show credentials to obtain the profile ID. See the command line reference for further details.

To configure SSH authentication using a public/private key (requires sudoer permission):

1. If the new keys do not yet exist, create a pair of SSH private and public keys:

   ssh-keygen -t rsa -C "<USER>"
   

2. Copy the SSH public key to each switch that you want to upgrade using one of the following methods:

   • Manually copy the SSH public key to the /home/<USER>/.ssh/authorized_keys file on each switch, or
   • Run ssh-copy-id USER@<switch_ip> on the server where you generated the SSH key pair for each switch

3. Add these new credentials to the switch:

   cumulus@switch:~$ netq lcm edit credentials ssh-key PUBLIC_SSH_KEY
   

1. On the Access Profiles card, select View profiles.

2. From the list of profiles, select Delete in the profile’s row.

The delete icon only appears next to custom profiles that are not already attached to a switch.

3. Select Remove.

1. Run netq lcm show credentials. Identify the profile you’d like to delete and copy its identifier from the Profile ID column. The following example deletes the n-1000 profile:

cumulus@switch:~$ netq lcm show credentials
Profile ID           Profile Name             Type             SSH Key        Username         Password         Number of switches                   Last Changed

2. Run netq lcm del credentials profile_id <text-credential-profile-id>:

cumulus@switch:~$ netq lcm del credentials profile_id credential_profile_3eddab251bddea9653df7cd1be0fc123c5d7a42f818b68134e42858e54a9c289

3. Verify that the profile is deleted with netq lcm show credentials.

1. Open the LCM dashboard.

2. On the Access Profiles card, select View profiles.

To view a list of access profiles and their associated credentials, run netq lcm show credentials.

If you use an SSH key for the credentials, the public key appears in the command output.

If you use a username and password for the credentials, the username appears in the command output with the password masked.
