This page allows you to manage the network infrastructure for the OtterScale cluster. You can manage network fabrics, VLANs, and subnets for machine provisioning and service connectivity.
Statistics Overview
Section titled “Statistics Overview”At the top of the page, a set of summary cards provides a quick overview of the configured networking resources.:
Available Subnets
Overall utilization of IP address space across all subnets.
Introduction
Section titled “Introduction”The Networking page displays a list of configured networks. The table includes the following information:
| Column | Description |
|---|---|
| Fabric | The physical network fabric associated with the network. |
| VLAN | The Virtual LAN (VLAN) ID and name. |
| DHCP On | Indicates whether DHCP is enabled for this network. |
| Subnet | The CIDR notation of the subnet (e.g., 192.168.1.0/24) and the Gateway IP address. |
| IP Address | The number of IP addresses currently in use or reserved. |
| IP Range | The configured IP ranges for dynamic allocation. |
| Statistics | Visual representation of IP address usage (Available vs. Total). |
Manage Networks
Section titled “Manage Networks”A Fabric represents a physical or logical L2 broadcast domain. Within each Fabric, you can define VLANs. Each VLAN containes one Subnet, which represent routable IP networks used for DHCP, PXE booting, and machine allocation. You can create new networks or manage existing ones using the Actions menu (three dots icon) in each row.
Create a New Network
Section titled “Create a New Network”To add a new network configuration:
