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.

3. Begin initial configuration using the initialization procedure displayed:

Note: IPv6 addresses are supported 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.

Connected to Switch; nvOS Identifier:0x000044; Ver: 0.19.3398


Note: In order to use the phone home feature, you must open ports 8084 and 8843 on your firewall.

When you setup a switch for initial configuration, you can disable host-facing ports until you are ready to plug in host cables to the switch.

If no adjacency is detected on a port during the quick-start procedure, the ports remain in the disabled state.

To enable the ports after plugging in cables, use the port-config-modify port port-number host-enable command.

Host ports are enabled by default unless you specify no during the quick-start procedure.

With switch-setup Enable host ports mode set to no, all ports have this port-config-setting set to no.

This can be viewed using the following command:

CLI (network-admin@Spine1) > port-config-show format port,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 LLDP packets are received and an adjacency is formed, Netvisor One continues normally.

If no adjacency is found in 5 seconds, Netvisor One flags the port as host-disabled.

With this flag set, only LLDP packets are accepted and packet transmission is not initiated.

After switch discovery and fabric creation is complete and you want to enable host, server, or router traffic switching, enable the ports using the host-enable option:

CLI (network-admin@Leaf1) > port-config-modify port 5 host-enable

switch-setup-show displays enable-host-ports setting. You cannot change this global switch setting after the first initial switch-setup is performed.

However, you can configure individual ports for host-enable or disable by using the port-config-modify command.
