2.4.3. Day-1 configuration¶

Automatic Day-1 configuration¶

Virtual Service Router includes a Day-1 configuration mechanism that starts a DHCP client on the first interface and enables a SSH server on it, so that the user can remotely access the console.

Check the VRF main state:

vsr> show state vrf main
vrf main
    (...)
    interface
        physical ens3
            oper-status UP
            ipv4
                address 10.0.2.15/24
                ..
        (...)
    ssh-server
        port 22
        enabled true

Here, we see that the ens3 interface in the main VRF is configured with an IP address and that SSH is enabled. You can jump to Configuring the fast path. If the automatic Day-1 configuration doesn’t match your needs, you can perform manual Day-1 configuration:

Manual Day-1 configuration with static IP address¶

To configure an address on the management interface and enable SSH from the CLI, proceed as follows:

Start to edit the running configuration:
```
vsr> edit running
vsr running config#
```
Create an interface named eth0 on top of the pci-b0s3 port, in the main vrf:
```
vsr running config# vrf main interface physical eth0
vsr running physical eth0#! port pci-b0s3
vsr running physical eth0# commit
```
Note

use show state / network-port to see the list of available network ports with PCI ids; it can help choosing the right management port.

Add an address to the management interface and apply the changes:

vsr running physical eth0# ipv4 address 192.168.0.2/24
vsr running physical eth0# commit

Check that the system state for the new interface is correct:

vsr running physical eth0# show state
physical eth0
     oper-status UP
     enabled true
     mtu 1500
     ipv4
          address 192.168.0.2/24
          (...)
     port pci-b0s3
     (...)

Add a default route:

vsr running physical eth0# / vrf main routing static
vsr running static# ipv4-route 0.0.0.0/0 next-hop 192.168.0.1
vsr running static# commit

Enable SSH server:

vsr running static# / vrf main ssh-server
vsr running ssh-server# commit
vsr running ssh-server# exit

Now the equipement can be accessed via a remote SSH client at address 192.168.0.2.

To make this configuration applied at each startup, make it the startup configuration:
```
vsr> copy running startup
Overwrite startup configuration? [y/N] y
```

Manual Day-1 configuration with DHCP¶

To configure an address, a default route via DHCP on the management interface, a DNS and enable SSH from the CLI, proceed as follows:

Start to edit the running configuration:
```
vsr> edit running
vsr running config#
```
Create an interface named eth0 on top of the pci-b0s3 port, in the main vrf:
```
vsr running config# vrf main interface physical eth0
vsr running physical eth0#! port pci-b0s3
vsr running physical eth0# commit
```
Note

use show state / network-port to see the list of available network ports with PCI ids; it can help choosing the right management port.

Enable DHCP on the management interface and apply the changes:

vsr running physical eth0# ipv4 dhcp
vsr running dhcp# commit

Check that the system state for the new interface is correct:

vsr running physical eth0# show state
physical eth0
    (...)
    ipv4
        dhcp
            dhcp-lease-time 7200
            enabled true
            current-lease
                renew 3 2018/07/04 04:04:15
                fixed-address 10.0.2.15
                expire 3 2018/07/04 16:26:02
                rebind 3 2018/07/04 13:26:02
                (...)
        address 10.0.2.15/24
        (...)
    port pci-b0s3
    (...)

Configure the DNS:

vsr running physical eth0# / vrf main dns server 1.1.1.1
vsr running physical eth0# commit

Enable the SSH server:
```
vsr running physical eth0# / vrf main ssh-server
vsr running ssh-server# commit
vsr running ssh-server# exit
```
Now the equipement can be accessed via a remote SSH client using the address acquired by DHCP (in our case 10.0.2.15).
To make this configuration applied at each startup, make it the startup configuration:
```
vsr> copy running startup
Overwrite startup configuration? [y/N] y
```
