NETLAB+ AE & PE Customers: Please refer to the NETLAB AE & PE Control Devices page.


NETLAB+ may be used to facilitate access to lab equipment. Control devices are required in order to provide internal connectivity, console access, and managed power to lab devices. Control devices are dynamically managed by NETLAB+ and are not accessible or configurable by end users.

Lab devices and control devices are required in order to support Cisco Networking Academy lab content.


The control device models listed on this page have been tested and are recommended specifically for NETLAB+ VE. Other device models used for NETLAB+ AE/PE may also function. Please refer to the NETLAB+ AE & PE Control Devices page.

 

Control Switches

Control Switch

Control switches connect real lab equipment to NETLAB+ and virtual infrastructure. Control switches are not accessed by lab users.


Master Control Switch

The master control switch is a core switch that provides connectivity between lab equipment racks, the virtual machine infrastructure and the NETLAB+ VE virtual machine. The following table lists the Cisco switch models supported by NETLAB+ VE for use as a master control switch.

Switch Model Minimum Required Image Ports Uplinks Max VLANs Comments
Cisco WS-C2960+24TC-L 12.2.25 24 2 250 Recommended as master control switch in new installations.
Cisco WS-C2950T-24 12.1(22)EA2 (EI) 24 2 250 Recommended if already on-hand. "T" model with uplinks required.
Cisco WS-C3650-24-TS-E 03.06.05.E 24 4 1000 OK as master control switch in large install (5-7 racks).

Secondary Control Switches

Your NETLAB+ system will include one or more secondary control switches; the number of control switch ports needed depends on the type and number of standard racks you will be adding to your system. The following table shows the supported switch models and quantity required per standard rack.

Switch Model Minimum Required Image Ports Uplinks # Per Rack Comments
Cisco WS-C2960+48TC-L 12.2.25 48 2 1 Recommended for new installations in standard racks. “Plus” model and LAN Base image required.
Cisco WS-C2960+24TC-L 12.2.25 24 2 2 Recommended if already on-hand.
Cisco WS-C2950T-24 12.1(22)EA2 (EI) 24 2 2 OK if already on-hand. "T" model with uplinks required.
 

Access Servers

Access Server

Access servers provide console connections to lab equipment. Using this approach, users can access lab gear even when no configurations have been loaded in the lab devices. NETLAB+ proxies all connections through the access server. This special proxy allows simultaneous sharing of console ports and allows all users to access the lab environment using a single IP address and single remote access port.

When using a HWIC-16A on a router (2811, 2901, or 2911) with IOS 15, you must use version 15.1.4M4(MD), due to a Cisco bug. NDG has tested 15.1.4M4(MD) on all platforms. Please refer to the table and footnotes below.

Router Async Line Card(s)
Qty X Type

3 Cuatro 2U rack only requires 3 octal cables per rack.

4 When using an HWIC-16A on a router (2901or 2811) with IOS 15, you must use an IOS version that has been tested by NDG, due to a Cisco bug. NDG has tested 15.1.4M4(MD) on all platforms.

5 For Cisco 2811 only: Using HWIC-16A on a router with IOS 12 does not exhibit the bug mentioned in the footnote above.

 

Power Distribution Units

Power Distribution Unit

Power Distribution Units provide managed electrical power, allowing NETLAB+ and users to turn lab equipment on and off. The power of each managed device in a NETLAB+ equipment pod is connected to an American Power Conversion (APC) Switched Rack PDU. This provides three functions:

  • Reboot devices during NETLAB+ automated operations.
  • Allow users to control power of a lab device (making password recovery possible).
  • Power off devices when not in use to reduce energy and cooling requirements.

Each APC Switched Rack PDU provides eight (8) managed outlets. The following table lists the Power Distribution Units supported by NETLAB+ VE.

Power Distribution Unit Outlets Voltage Input (Plug) Outlet (Receptacles)
APC AP79001,2 8 115 VAC NEMA 5-15P
(8) NEMA 5-15R
APC AP79201,2 8 208-230 VAC IEC-320 C14
