Supported Control Devices
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.
NETLAB+ Control Plane
Control Switches
Control Switch
NETLAB+ uses a control switch to provide connectivity between the NETLAB+ server, access servers, remote PCs, and switched outlet devices. Control switches are not accessed by lab users.
The following table lists the Cisco switch models supported by NETLAB+ for use as a control switch.
| Cisco Switch Model | Minimum Required Image | Number of Available VLANs |
|---|---|---|
| Catalyst 2950-12 | 12.1(22)EA2 - EA6 | 641 |

| Catalyst 3550-12 | 12.1(22)EA2 | 1000 |
| Catalyst 3550-24 | 12.1(22)EA2 | 1000 |
| Catalyst 3550-48 | 12.1(22)EA2 | 1000 |
1Be especially aware of this limit when using these switches, since the number of available VLANs is significantly less than other models. As shown in this example, these switches may not be adequate to support the number of pods that you plan to install on your NETLAB+ system.
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.
The following routers and access server modules are supported. Combinations using HWIC-16A are currently recommended. Cisco NM-32A modules and 25XX routers are now end-of-life and can no longer be purchased new.
| Platform | Cisco NM-32A |
Cisco NM-16A |

Access Server Octal Cables
Cisco HWIC-16A, NM-32A, and NM-16A modules use special octal cables to connect from
the module to lab device console ports. Each octal cable supports 8 lab device connections.
The following table lists the octal cable part number and cable quantity required
to connect all ports on the module.
| Module | Octal Cable Part Number | Quantity Required |
|---|---|---|
| Cisco HWIC-16A | CAB-HD8-ASYNC | 2 | Cisco NM-32A (EOL) | CAB-OCTAL-ASYNC | 4 | Cisco NM-16A (EOL) | CAB-OCTAL-ASYNC | 2 |
Switched Outlet Devices
Switched Outlet Device
Switched outlets 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 Switched Outlet devices supported by NETLAB+.
| Switched Outlet Device | Outlets | Voltage | Outlet Type |
|---|---|---|---|
| APC 7900 Switched Rack PDU | 8 | 120V |
NEMA 5-15R

| APC 7920 Switched Rack PDU | 8 | 208V |

NEMA 5-15R
|
| APC 9212 Master Switch (end of sales) |
8 | 208V |
IEC 320 C13
|
The AP7920 and AP9212 are for countries with 200-240 VAC power. Eight (8) IEC-320 C13 outlets are provided. This will require (8) C13 to C14 power cords such as the AP9870 (sold separately). One (1) IEC-320 C14 inlet is provided on the input side. The C14 connector is the same used on a Cisco router or switch.
