The RackSwitch G8332 with Cloud NOS offers the following additional features:

• Automated VM-aware network provisioning

  The Lenovo CNOS Network Policy Agent, a ThinkAgile Network Orchestrator feature, gives increased visibility of the Nutanix (AOS version 5.0.2 or higher [excluding 5.1.2]) and VMware vSphere virtual infrastructure, including VM and virtual network information. It provides automated VM-aware provisioning by automatically configuring VLANs in the physical network based on the auto-discovered virtual network topology. The agent also performs ongoing dynamic updates to the physical network configuration in response to new VMs, updated VMs, and deleted VMs and virtual networks, eliminating errors with manual configuration.

• Proactive congestion monitoring

  Telemetry enables continuous monitoring of networking devices to detect potential congestion problems, such as packets dropped by the switch when ports are being used close to their line rate or switch buffers are being temporarily overflown (for example, in case of microbursts).

• Zero Touch Provisioning

  Zero Touch Provisioning (ZTP) enables a switch to automatically provision itself using the resources available on the network, without manual intervention. ZTP automatically handles the process of upgrading the switch software image and installing configuration files.

• Python Scripting

  You can create and execute local Python scripts on switches to make small programs that allow a switch to automatically provision itself, perform fault monitoring, upgrade the image files, or auto-generate configuration files. You can implement version control systems, automatically generate alerts, create custom logging tools, and automate the management of network devices.

• REST API Programming

  The Lenovo REpresentational State Transfer (REST) Application Program Interface (API) enables you to remotely configure and manage a Lenovo switch using REST and HyperText Transfer Protocol (HTTP). It also allows integration into management applications, such as Lenovo XClarity.

The RackSwitch G8332 with Enterprise NOS offers the following additional features:

• Transparent networking capability

  With a simple configuration change to Easy Connect Mode, the RackSwitch G8332 becomes a transparent network device that is invisible to the core and eliminates network administration concerns of Spanning Tree Protocol configuration and interoperability and VLAN assignments and avoids any possible loops. By emulating a host NIC to the data center core, it accelerates the provisioning of VMs by eliminating the need to configure the typical access switch parameters.

• OpenFlow enabled

  The RackSwitch G8332 offers the benefits of OpenFlow. OpenFlow is an open application programming interface (API) with which the network administrator easily configures and manages virtual networks that control traffic on a “per-flow” basis. It also creates multiple independent virtual networks and related policies without dealing with the complexities of the underlying physical network and protocols. The RackSwitch G8332 is also the ideal switch to use with industry compliant OpenFlow controllers.

• Network address translation

  Network Address Translation (NAT) allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network. Therefore, only a single, unique IP address is required to represent an entire group of local IP addresses to the external network. In addition to reducing the number of public IP addresses that are required, NAT provides security by acting as a firewall between internal and external networks.

The following table compares high level features of the CNOS and ENOS.

* Not all ENOS features support IP v6 addressing, including DHCP, BGP, VRRP, and TACACS+/RADIUS/LDAP.
** Supported with the Nutanix AOS version 5.0.2 or higher (excluding 5.1.2) or VMware vSphere.

The RackSwitch G8332 comes with a limited 3-year hardware warranty with Next Business Day (NBD), 9x5, Customer Replaceable Unit (CRU) warranty service and includes a 3-year software license, which provides entitlement to upgrades over that period. The options that are installed in the switch assume the switch’s base warranty and any Lenovo warranty service upgrade for the switch. Lenovo also allows one no-charge support call within 90 days of purchase to get assistance and help resolve problems with the configuration of recently purchased Lenovo network switches.

Some regions might have different warranty terms and conditions than the standard warranty. This is due to local business practices or laws in the specific region. Local service teams can assist in explaining region-specific terms when needed. Examples of region-specific warranty terms are second or longer business day parts delivery or parts-only base warranty.

If warranty terms and conditions include onsite labor for repair or replacement of parts, Lenovo will dispatch a service technician to the customer site to perform the replacement. Onsite labor under base warranty is limited to labor for replacement of parts that have been determined to be field-replaceable units (FRUs). Parts that are determined to be customer-replaceable units (CRUs) do not include onsite labor under base warranty.

If warranty terms include parts-only base warranty, Lenovo is responsible for delivering only replacement parts that are under base warranty (including FRUs) that will be sent to a requested location for self-service. Parts-only service does not include a service technician being dispatched onsite. Parts must be changed at customer’s own cost and labor and defective parts must be returned following the instructions supplied with the spares parts.

Also available are Lenovo Services warranty maintenance upgrades and post-warranty maintenance agreements, with a well-defined scope of services, including service hours, response time, term of service, and service agreement terms and conditions.
