Thank you for purchasing the latest innovation in Tap technology, the iTap 10 GigaBit Port Aggregator (iTap Port Aggregator). This device provides

ultra‑efcient access to critical 10 Gigabit full‑duplex links using only one NIC on

each monitoring tool, and supports two tools simultaneously. In addition, the iTap feature gives you a quick visual reference of link performance: Bandwidth utilization is monitored and displayed on the front panel and through remote interfaces so you can see exactly what is happening on both sides of the network link. The iTap Port Aggregator also features a Tap mode, timestamping, and packet slicing.

About this Guide

This guide describes the installation and use of the following models:

Introduction

Features

Front Panel Display

The front panel display and alarm LEDs provide a quick visual check that link utilization levels are not exceeding the capacity of the monitoring device or a pre-determined threshold. From the display, you can view the current bandwidth utilization of each side of a full-duplex link, and the monitor ports, along with the size and time of the peak utilization for each port. After taking action on a utilization or peak event, you can reset the data from a recessed reset button on the front panel or remotely. With iTap technology, you have the information and the access points you need to respond quickly to network events.

iTap 10 GigaBit Port Aggregator

Performance Aggregation

The iTap Port Aggregator combines and regenerates both directions of a full-duplex

stream, sending all aggregated trafc to two separate monitoring ports. Typically,

full-duplex monitoring with a network tap requires two network interface cards (NICs) (or a dual channel NIC), one interface for each side of the full-duplex link. Net Optics’ iTap Port Aggregator enables one or two devices to simultaneously monitor a full-duplex link using only one NIC per device.

After the trafc has been aggregated to a single ow, it is difcult for the monitoring

tool to distinguish the utilization levels of each side of the bi-directional link. The iTap Port Aggregator tracks the utilization levels before aggregation, keeping this vital information easily accessible from its remote and command line interfaces.

Remote Access

The iTap Port Aggregator is accessible from remote interfaces that provide information and control from anywhere in the network. Web Manager and System Manager software communicate over the remote interfaces to enable you to remotely set

parameters, view status information, and monitor trafc statistical data. These tools

provide security and performance information including the number of packets and bytes transferred, and the CRC error count. You can remotely set the alarm

thresholds, clear the trafc data counters, and turn on or off a Monitor Port using a

Web browser and the IP address of the Aggregator. The remote interfaces operate through a dedicated Management Port that can be connected to the network or isolated on a dedicated management VLAN for increased security.

Security, Visibility, and Reliability

A monitoring device connected to the iTap Port Aggregator sees all full‑duplex trafc

including Layer 1 and Layer 2 errors. Redundant power connections provide uptime

protection. You have the option of conguring the iTap Port Aggregator so that it will

not show data on the display. You can also turn off the Management Port, thereby preventing the device from being accessed over the network. In addition, Monitor Ports can be turned off to prevent unauthorized access to the network link.

Tap Mode

The iTap Port Aggregator can operate as a Port Aggregator (AGG mode) or as a

conventional network Tap (TAP mode). In Tap mode, the device bridges all trafc between Network Ports A and B, while copying trafc from Network Port A to

Monitor Port 1, and Network Port B to Monitor Port 2.

iTap 10 GigaBit Port Aggregator

User-dened Maximum Packet Size

The user can set a maximum packet size of 64 to 12,000 bytes for each network port. If any oversized packets are received (the packet length exceeds the programmed value), they are counted and discarded. This function enables the iTap Port Aggregator

to pass jumbo packets, but discard packets that are oversized as dened by the user.

Timestamping

When the timestamping feature is enabled, the iTap Port Aggregator replaces each packet's CRC with a timestamp before it is sent to the monitoring tool. The timestamp records the exact time that the packet arrived, and which Network Port it arrived from, so events can be correlated with other data.

The timestamp is a 32-bit value. A 30-bit timer is contained in the lower part of the timestamp. The timer increments every 6.4 nanoseconds (156 Mhz). The two most

signicant bits indicate the Network Port: 00 means Port A and 10 means Port B.

Optionally, a new CRC can be regenerated and appended to the packet so the

monitoring tool does not see CRC errors due to the changed eld. (See following

section, CRC Regeneration.)

Packet Slicing

Sometimes it is desirable for monitoring tools to see only packet headers and not the packet payload. For example, when executing a lawful intercept, it may be illegal for the monitoring tool to read the packet payload. Another reason for passing only the packet headers is to reduce the bandwidth requirement on the monitor ports.

The iTap Port Aggregator supports this requirement by providing a packet slicing

function. When packet slicing is enabled, a user‑congurable number of bytes at the

beginning of each packet are copied to the monitor ports, and the rest of the packet is discarded. (Of course, the full packets are always passed between Network Ports A and B.) Optionally, a new CRC can be regenerated and appended to the packet so the monitoring tool does not see CRC errors due to the truncated packets. (See

Regeneration

on the following page.)

CRC

iTap 10 GigaBit Port Aggregator

CRC Sanitizing

The iTap Port Aggregator can be set to drop packets from the monitoring data stream if they are received with CRC errors. This function can clean up the data being sent to monitoring tools, or it can be left off so the monitoring tool can see the packets that have CRC errors. In either case, packets received with CRC errors are counted and reported in the Port Statistics. All packets are always passed between

Network Ports A and B regardless of CRC errors; this option only affects the trafc

sent out the Monitor Ports. CRC Sanitizing is activated by setting Drop Bad Packet to ON.

CRC Regeneration

The iTap Port Aggregator can regenerate good CRC check bytes for packets as it copies them to the Monitor Ports. The four bytes of regenerated CRC are appended to the packet. For example, if packet slicing is set to 64 bytes, the resulting packet with CRC Regeneration is 68 bytes at the Monitor Port.

Timestamping and packet slicing inherently create packets with bad CRCs, so use CRC Regeneration if you don't want the monitoring tool to receive timestamped or sliced packets with CRC errors.

However, note that CRC Regeneration also converts packets with CRC errors to good packets before copying them to the monitoring tool. This situation should be avoided because the monitoring tool won't know the packets were received with CRC errors. Therefore, whenever CRC Regeneration is ON, it is advisable to turn on CRC Sanitizing as well, to prevent packets received with CRC errors from going to the Monitor Ports at all.

SNMP Traps

If data is not displaying as expected, check the Network Port connectors for link status and activity. Also check the status of the Display using the CLI. When the

display is in the OFF state, it shows "Net Optics, Inc." and the rmware compile date.

Utilization Alarm LEDs

Four LEDs indicate that utilization levels have exceeded the threshold. Each LED is the alarm for one port. For Network Ports, utilization is monitored on incoming

trafc; for Monitor Ports, the outgoing trafc is monitored. When a Utilization

Alarm LED is illuminated, it indicates that the threshold level was exceeded for that port since the last reset. The LEDs remain illuminated until they are reset using the reset button or remote interfaces.

Link LEDs

Four LEDs indicate link status. If a good link is established on a port, the LED corresponding to that port illuminates. The Link LED blinks when trafc is passing through the port; the intensity of the blinking increases with the utilization; it becomes noticeable for utilizations of about 30 percent or greater.

Mode LEDs

If the device is in Tap mode, the TAP LED illuminates. If the device is in Aggregation mode, the AGG LED illuminates. (If both mode LEDs are illuminated or both are off, check that the Mode bits are set to the same value for both Monitor Ports.)

Power LEDs

If the iTap Port Aggregator is deployed with both power supplies, both power LEDs illuminate when connected to power. If a power LED is off, the corresponding power supply is disconnected or not functioning.
