Using the Serial Console Port for Initial Configuration


This procedure assumes that you have installed the switch in the desired location and it is powered on.



Warning:  Do not connect any ports to the network until the switch is configured. You can accidentally create loops or cause IP address conflicts on the network.



If you are going to cable host computers to the switch, there is an option to enable or disable host ports by default.


  1. Connect the console port on the rear or front (depending on the model) of the switch to your laptop or terminal concentrator using a serial cable.
  2. From the terminal emulator application on your computer, log into the switch with the username network-admin and the default password admin.


Note: Netvisor ONE supports both IPv4 and IPv6 addresses for the in-band interface.



Warning: Be sure to type in a static IP address for the management interface during the initial configuration. Netvisor One initially uses DHCP to obtain an IP address, but DHCP is not supported after the initial configuration.


  1. Begin the initial configuration using the initialization procedure displayed.
  2. Enter the following details when prompted, an example is provided in the output below:


    • Accept the EULA agreement
    • Type-in the switch name. An example is provided in the output below.
    • Enter and re-enter the password
    • Enter the Management IP and netmask. An example is provided in the output below.
    • Enter the In-band IP and netmask. An example is provided in the output below.
    • Enter the IP address of the Gateway.
    • Enter the IP address for the primary and secondary DNS.
    • Enter the domain name.

When you setup a switch for initial configuration, the host facing ports are enabled by default. However, you can disable the host ports until you are ready to plug-in host cables to the switch. If Netvisor ONE does not detect adjacency on a port during the quickstart procedure, the ports remain in the disabled state.


To enable the ports after plugging in cables, use the port-config-modify port port-list host-enable command. Netvisor ONE enables host ports by default unless you specify NO during the quickstart procedure as displayed below.

To verify, use the command:


CLI (network-admin@taurus-ext-01) > port-show port 9,10


switch                  port         bezel-port         status                       config

-------------          ----         ----------        --------------------         ------

taurus-ext-01           9                3          phy-up,host-disabled         10g

taurus-ext-01           10              3.2        phy-up,host-disabled         10g



To enable the port (s), use the command:


CLI (network-admin@taurus-ext-01) > port-config-modify port 9,10 enable host-enable


CLI (network-admin@taurus-ext-01) > port-show port 9,10


switch        port   bezel-port                  status                      config

------------- ----   ----------                  ----------                  ------

taurus-ext-01         9             3                   up,vlan-up                  fd,10g

taurus-ext-01         10           3.2                 up,vlan-up                  fd,10g



You cannot disable the host-ports once it is enabled during the switch setup process. Netvisor ONE displays an error:


CLI (network-admin@taurus-ext-01) > switch-setup-modify disable-host-ports


switch-setup-modify: disable/enable host ports can be set only at initial switch-setup time


During the initial configuration of the switch, if the host ports are disabled, then all ports having the same port configuration will be disabled. This can be viewed using the following command:


<CLI (network-admin@Spine1) > port-config-show port port-list host-enable


In this mode, when any port comes up physically, Netvisor ONE automatically sends and receives LLDP packets to look for peer switches. If Netvisor ONE does not detect an adjacency within  5 seconds, the port is flagged as host-disabled. With this flag set, Netvisor ONE only accepts LLDP packets and does not initiate packet transmission.


CLI (network-admin@taurus-ext-01) > port-config-show port 9,10


switch        port   bezel-port          status                                                 config

------------- ----   ----------         ----------                                            ------

taurus-ext-01         9             3          up,vlan-up,PN-other,LLDP                  fd,10g

taurus-ext-01         10           3.2        up,vlan-up                                             fd,10g


After completing switch discovery and fabric creation, use the host-enable option to enable host, server, or router traffic switching, and ports:


CLI (network-admin@taurus-ext-01) > port-config-modify port 9 host-enable
