C410/C420 configuration via WebUI

During installation, the hostname (KB-XX-XX-XX) of the C410/C420 device is added to the CN responder list for the specific distribution node (DN) device to which it connects. That configuration change for the distribution node initiates the wireless link between the the distribution node and the C410/C420 client node.

After the C410/C420 link to the network is active, you can access the WebUI using one of the following methods:

  • Link from the WebUI of the connected distribution node (DN). On the Status page of the connected distribution node, in the Wireless section, click on the device listed in the Peer-Name column.  

  • Access the WebUI of the C410/C420. In your browser's address bar, type:

    https://hostname

    where hostname is the hostname (KB-XX-XX-XX) or IP address of the radio. See Connecting to the AltoPlex radio for more information.

  • If using the AltoCommand web-based management tool, access the WebUI from the Devices page. On the row of the device to configure, click the menu icon () in the settings () column and click Connect to Device.

General startup configuration steps for the C410/C420 often include:

  • Click on the Admin tab and do one or more of the following:
    • Upgrade Firmware
    • Change Password
    • Set the Location
    • Set the Description
  • On Network tab, set network configuration items for the management network interface and VLAN.

The header of the WebUI shows the Unit Name of the device, (also called the hostname), Description and Location, as well as offering a login link. Login is not required to view read-only information about the device, but is required to set configurations on any other tab of the WebUI.

 

Status tab

The Status tab shows a summary of information about the device, its wireless and LAN connections, and interface information.

Status tab — Device information

This section describes the model of the device, the device's role (CN — client node), Ethernet MAC address, firmware version, device uptime, status of its connection to the AltoCommand server, GPS information, and device temperature.

The AltoCommand server is configured on the distribution node.

Status tab — Wireless

Displays information about the device's wireless connection to a distribution node.

Status tab — LAN interfaces section

This section shows information for the LAN interface (Port 1 for the C410 and C420), including whether the port is enabled, its status (Connected or Not connected), duplex mode, speed, maximum supported speed, and PoE mode.

If the device's Ethernet port is connected via a switch to other AltoPlex devices, the hostnames of connected devices will be included in the LL Discovery field. Clicking a device's hostname in the LL Discovery field will open the WebUI for that device. This is useful to determine which devices are co-located (for example, devices that are installed on the same pole).

LL Discovery requires that the devices are connected by an unmanaged switch, or a managed switch that is configured to forward LLDP packet information.

Status tab — Management interface

This section lists the IP address and whether the address is dynamic or static, the subnet mask, and default gateway for the management interface on the node.

Admin tab

Unauthenticated users can view read-only information about the device in the WebUI.  To make changes to the configuration, you must be logged in as an administrator.

Click the login link in the WebUI header to log in as administrator. The default password is admin.

The Admin tab has two sections: Device control and Configuration.

Admin tab — Device control section

This section lists the firmware version on this device. This section also offers controls for the following tasks:

Upgrade Firmware — Updates the device firmware with the file you upload. Click the Upgrade Firmware button and browse to and upload the firmware upgrade file. Then click Start Upgrade. The device will reboot as part of the upgrade process. For more detailed steps see Upgrade firmware.  

The AltoCommand management interface also offers a convenient way to review firmware version compliance for all AltoPlex devices in your network, and upgrade them from the Devices list. See the AltoCommand User Guide for more information.

Firmware upgrade dialog

Change Password — Use this button to change the password for the admin of the C410 and C420. See Change a device password for instructions.

Locate Unit — Click this button to put the unit into locate mode. In locate mode, the device flashes the LED in a specific sequence so that field personnel can identify the unit. The LED sequence is: LED flashes red and green.

Download Diagnostic File — Automatically downloads a detailed diagnostic text file for the device. The file contains detailed information about the device and its status at the time of the download. The file name includes the hostname, the date and time. For example, a file named KB-C7-00-01_diag_2025-11-07-14-43-32.txt, means this is the diagnostic text file for the device KB-C7-00-01, created at 2:43:32 pm (UTC) on November 7, 2025. See Download a diagnostic file for instructions.

Reboot Unit — Restarts the unit remotely. See Reboot for instructions.

Restore Factory Defaults — Restores all device configuration to factory defaults. If the unit is unreachable and cannot be reset with this button, it may require a hard factory reset. See the Factory Reset topic for instructions.

Factory reset returns the unit’s password to the default: admin. Since the IP assignment uses DHCP by default, the factory reset is not likely to affect the IP address of the device, unless it has been configured to use a static IP address.

Admin tab — Configuration section

This section includes the following settings:

Location — Use this field to describe the physical location where the device is installed. Allows up to 130 characters.

Description — Use this field to provide a description of the device. This may include orientation, function, role or other information about the device. The AltoCommand web-based management tool can automatically use this field as a Switch point tag, when populating the network map, so similar but unique descriptions are recommended. Allows up to 130 characters.

Link state LED — Enables or disables the LED for displaying the node status. See LED indicators.

 

Wireless tab

You can change the 60 GHz airlink SSID and encryption passkey from the Wireless tab.

All AltoPlex devices have the same default SSID and encryption passkey for their 60 GHz airlink. Generally, this is sufficient because the devices will only form links to radios that are specified in their configuration.

All linked radios must have the same SSID and encryption passkey. If you change the SSID and/or passkey, they must be changed for all linked radios or the links will not form.

When changing the SSID and passkey for radios that are already installed in the field, begin with client nodes, and then the most remote distribution nodes, moving backwards towards the point of presence. This insures that you will have access to all radios during the process.

To change the SSID and encryption passkey for the 60 GHz airlink:

  1. Click the login link in the WebUI header to log in as administrator. The default password is admin.

  2. For 60 ghz airlink SSID, type the new SSID.
  3. For 60 ghz airlink encryption passkey, type the new encryption passkey.
  4. A confirmation screen will remind you that the SSID and passkey must be the same for all linked devices, and will indicate that the device will reboot in order to complete the change. Click Yes to confirm.

Network tab

The Network tab offers settings for Management Network Interfaces, VLAN configuration and Port Isolation, as well as additional Layer 2, SNMP, Network Services, and DHCP settings. The Network tab has a long list of settings, so the images below show only one section at a time with brief descriptions following. 

Adding a C410/C420 device's hostname (KB-XX-XX-XX) to the CN responder list in a distribution node's (DN) configuration initiates the wireless link between the DN and the C410/C420. These devices are designed to work with other AltoPlex devices out of the box.

Network tab — Network Reachability Configuration

Management Network Interface Configuration — IP assignment method is Dynamic by default. If set to Static, the IP address, network mask and network gateway must be set.

Virtual LAN Configuration — Enable/disable the 802.1q VLAN mode, setting VLAN IDs, accepted frame types, PVIDs and memberships as required for your specific network operation. 

Port Isolation — Enable/disable the port isolation for each port interface on the unit by checking/clearing the box. 

Network tab — Spanning Tree Protocol Configuration 

Spanning tree protocol — Enable/disable spanning tree protocol (STP) by checking/clearing the box. If enabled, optionally set the bridge priority and port path cost for the wireless interface.

STP bridge priority is used to determine which device will serve as the root of the spanning tree. The device with the lowest priority will serve as the root. The priority configured here is a multiplier; to determine the actual STP priority, multiply by 4096.

The STP port path cost is used to determine the preferred path to the root. The path with the lowest cumulative cost is used.

The STP Ethernet port 1 bpdu filter prevents BPDU packets from being forwarded, which allows for separate networks to be isolated from participating in the same STP environment. When enabled, the filter is applied whether or not Spanning Tree Protocol is enabled.

Network tab — SNMP Configuration

Simple Network Management Protocol (SNMP) is used to monitor devices on a network for performance and error information. The settings in this section enable/disable SNMP and configure notification and community access settings.

The Altowav enterprise MIB can be downloaded at https://www.altowav.com/technology/assets/pdf/ALTOWAV-MIB.mib.

Network tab — Network Services Configuration

DNS IP list — A list of DNS server IP addresses using commas to separate the addresses.

Network tab — DHCP Relay Configuration (Option 82)

Enable the DHCP relay agent to:

  • Prevent unauthorized DHCP servers from serving IP addresses to devices on your network.
  • Insert a circuit ID into a DHCP message that identifies the source of the message. The DHCP relay agent circuit ID type can be either HWaddr (the MAC address of the C410/C420's Ethernet port, in ASCII format), or the Hostif (the hostname:Ethernet_port of the C410/C420 in ASCII format).

You can also select whether the Ethernet port is:

  • Trusted — All DHCP packets coming from devices attached to the Ethernet port will be forwarded.
  • Untrusted:
    • All DHCP server packets from attached devices will be blocked.
    • All DHCP client packets from attached devices that have option 82 information in their header will be blocked.
    • All DHCP client packets from attached devices that do not have option 82 information in their header will be fowarded, with the circuit ID appended.

    All wireless links are automatically considered trusted.
