Cisco Prime Network Analysis Module (NAM) 2300 Series Appliances Installation and Configuration Guide

Technical Specifications

---

The Cisco Prime NAM 2300 series appliances are based on the UCS C220 and UCS C240 servers. This appendix includes the following sections:

• Cisco Prime NAM 2304 Technical Specifications
• Cisco Prime NAM 2320 Technical Specifications
• SFP Port Cable Specifications
• Optical Tap Devices

Cisco Prime NAM 2304 Technical Specifications

The following table contains links to the technical specifications for the Cisco Prime NAM 2304 appliance.

For more information about the Cisco UCS C220 server, see the Cisco UCS C220 Server Installation and Service Guide.

Cisco Prime NAM 2320 Technical Specifications

The following table contains links to the technical specifications for the Cisco Prime NAM 2320 appliance.

For more information about the Cisco UCS C240 server, see the Cisco UCS C240 Server Installation and Service Guide.

SFP Port Cable Specifications

The Cisco Prime NAM 2300 series appliance uses two types of cables depending upon the transceiver module you use:

• The Cisco Prime NAM 2304 uses 1G SFP modules.
• The Cisco Prime NAM 2320 uses 10G SFP+ modules.

For SFP and SFP+ cabling specifications, see Installing the GBIC, SFP, SFP+, XFP, CXP, and CFP Optical Modules in Cisco ONS Platforms.

Optical Tap Devices

You can use an optical tap device to get a copy of traffic flows between two network devices. Passive taps, such as optical tap devices, ensure that the flowing traffic is not altered regardless of its connection to the NAM appliance and provide a very low point of failure.

Traffic flows will be interrupted while you connect an optical tap, but doing so should take less than a minute and can be done during a network maintenance window.

NAM appliances are designed to receive tapped network traffic from both directions, from multiple links simultaneously, and to accurately merge received traffic to a single stream for high precision analysis.

Although passive optical taps do not alter the network characteristics and dynamics of flowing traffic, an optical tap does reduce the signal strength, so care should be taken to follow the tap specifications including your network link length and tapping location.

Note Pay attention to the optical split ratio of your passive taps with regard to your optical cable lengths. If the cable between the two devices or the cable from the tap to your NAM appliance is very long, you might need to select a different split ratio other than 50/50 to make sure the receive side signals on your two devices and NAM appliance are all strong enough to not introduce any line errors. Refer to user instructions of your optical tap device for more information.

Table C-1 lists the 10 GE optical tap devices that have been successfully tested with the Cisco Prime NAM 2300 series appliance in a tap configuration.
