Introduction

Thank you for choosing Net Optics 10 GigaBit Fiber, GigaBit Fiber, or 10/100/1000
iBypass Switch, the most versatile intelligent iBypass Switches available today. This
guide is designed to help answer your questions and provide an installation reference.

Net Optics iBypass Switch with Heartbeat provides a permanent access port for in­line network security and monitoring. The iBypass Switch automatically switches

network trafc through added devices, or bypasses devices that are removed. The
intelligent iBypass Switch Heartbeat provides notications to protect network
trafc against both signal and power loss on an attached device.

About this Guide

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

Features

Heartbeat Packet

The iBypass Switch monitors the attached device by sending a Heartbeat packet
to the device. If the iBypass Switch does not receive the Heartbeat response, it

automatically switches network trafc to bypass the unresponsive device—even

if the device is still receiving power. The iBypass continues to send the Heartbeat,

and will restore trafc ow through the device as soon as the link is restored .For

special applications, you can customize the Heartbeat Packet rate from the iBypass
Command Line Interface (CLI) or Web Manager GUI.

Uninterrupted Trafc

This iBypass Switch supports fail-open monitoring with any 10 GigaBit device
when it shares the same power source as the device. As long as the iBypass Switch

is receiving power, it will divert network trafc to attached monitoring devices.
In this state, all trafc is routed directly to the monitoring device connected to the

iBypass Switch.

When the iBypass Switch loses power, trafc continues to ow through the

network link, but is no longer routed through the iBypass Switch. This allows
network devices to be removed and replaced without network downtime. Once

power is restored to the iBypass Switch, network trafc is seamlessly diverted to

the monitoring device, allowing it to resume its critical functions.

Simply Plug It In

10 GigaBit iBypass Switches use XFP transceivers and GigaBit iBypass Switches
use SFP transceivers. The port kit includes the cables you need to establish a
secure network connection point for inline devices, and the cable to connect
monitoring devices.

Bypass Detect

You can set the Monitor Ports to cycle on and off while the iBypass Switch is in
Bypass ON mode in order to trigger attached devices to alarms to a management

system. In Bypass Detect mode, the monitor ports will cycle through ve seconds
off followed by fteen seconds on. When the iBypass Switch returns to Bypass

OFF mode, the monitor ports remain on and the on/off cycle is discontinued.

Link Fault Detect

You can set the iBypass Switch to drop the remaining network link when one
side of the link fails. The Link Fault Detect (LFD) feature ensures that connected
devices are aware of a failure on both sides of the link.

Note ____________________________________________________________________

Net Optics warrants the operation of the iBypass Switches only with XFP and SFP
modules supplied by Net Optics.

Bypass Modes

The iBypass Switch with Heartbeat bypasses attached in-line device and sends

trafc straight through the network link when one of three events occurs:

• Power loss to the switch

• Link failure

• Application failure

iBypass Switches with Heartbeat

Two LEDs on the front of the iBypass Switch indicate whether the switch is
bypassing the connected appliance or not. When the Bypass ON indicator is
illuminated, the iBypass Switch has not received the heartbeat packet as expected
and directly connects Network Ports A and B.

Power Loss Bypass

The iBypass Switch protects link integrity when the attached monitoring device
loses power. To install the iBypass Switch for this type of protection, the switch
should share the same power source as the monitoring appliance. If you are using
redundant power supplies for the iBypass Switch, make sure that both monitoring
devices are connected to the same power source as the iBypass Switch device.

Heartbeat Bypass

The iBypass Switch with Heartbeat protects against both physical link failure
and application failure on the monitoring device. The iBypass Switch checks the
path through the monitoring device by sending a packet at a predetermined rate
(for example, once every millisecond from Monitor Port 1). The iBypass Switch
validates the path when it receives the packet on the Monitor Port 2. If the iBypass
Switch does not receive the packet as expected three times in a row (assuming the
Retry count is set to 3), the iBypass Switch automatically enters Bypass ON mode.
You can use the CLI or remote interfaces to change the number of the Heartbeat
packets required (Retry parameter 1-255) before the iBypass Switch enters Bypass
ON mode. The switch continues to send the bypass packet and will return to Bypass

OFF mode the rst time it receives a heartbeat packet on Monitor Port 2. The

contents of the default Heartbeat packet can be seen on page 41.

Manual Bypass

The iBypass Switch can be manually set to Bypass ON mode by setting the Heartbeat
Timeout parameter to 0 using the CLI or remote interfaces. It returns to normal
operation when the Timeout parameter is restored to a non-zero value. No Heartbeat
packets are transmitted when the iBypass Switch is in Manual Bypass mode.

Tap Mode During Bypass

Whenever the iBypass Switch is in Bypass ON mode, it operates as a full-duplex

breakout Tap, copying the trafc received at Network Port A to Monitor Port 1,
and trafc received at Network Port B to Monitor Port 2. This function enables the
attached device to monitor network trafc out-of-band, for instance to baseline the

system prior to putting the device in-line. The only difference from a normal network
Tap is that Heartbeat packets continue to be transmitted (if the Switch is not in Manual
Bypass mode) in order to detect when the monitoring tool comes back online.

Note: ____________________________________________________________________

When using the iBypass Switch as a network Tap, be sure to set the Bypass Detect
Feature to "OFF" so the ports remain on constantly.

__________________________________________________________________________

SNMP Traps

The iBypass Switch transmits SNMP traps for the following events:

• Bypass state changes

• Utilization exceeds the threshold on any port

• Any port link status changes

• Port manually disabled

• Either power supply state changes

Trafc Statistics

The iBypass Switch collects statistics about the trafc passing through each of

its ports. The statistics can be viewed and cleared using any of the management
interfaces.

The trafc statistics collected by the iBypass Switch on each of its ports are:

• Peak trafc rate

• Time of the peak trafc

• Current bandwidth utilization

• Total number of packets

• Total number of bytes

• Number of Cyclical Redundancy Check (CRC) errors

• Number of oversize packets

Note _________________________________________________________________

The trafc statistics counters are 32 bits wide, so the maximum value of each
counter is 4,294,967,295. The counters roll over to 0 after the maximum count
is reached. Be aware that, at 10 Gbps, the Total Bytes counter can roll over in
as short a time as 3.4 seconds and the Total Packets counter in 3.7 minutes.

If data is not displaying as expected, check the Network Port connectors for link
status and activity. Also check the status of the display command using the CLI
(see Using the Command Line Interface in chapter 2).

Threshold Alarm LEDs

Four LEDs indicate that utilization levels have exceeded the threshold. There is one

LED per port for incoming trafc on the front panel. When a Threshold Alarm LED is

red, it indicates that the threshold level was exceeded for that port since the last reset.
The LEDs remain illuminated until reset via the reset button or remote interfaces.
(Threshold alarm LEDs are not provided on the 10/100/1000 iBypass Switch.)

Link LEDs

Four LEDs indicate link status. If a good link is established, the LED illuminates a

steady green. If there is no current activity on this link, the LED ashes.

Power LEDs

If the iBypass Switch is deployed with both power supplies, both power LEDs
will illuminate when connected to power. If a power LED is off, the corresponding
power supply is not functioning or connected.

Reset Button

Press the Reset button to reset the trafc peak and time on the display and the
Threshold Alarm LEDs. To prevent accidental resets, the Reset button is recessed
from the front panel. To push the Reset button, use a thin, rigid tool such as an
unbent paperclip.

2. Slide the iBypass Switch into one of the slots and secure the device by
tightening the thumb screws.

3. Make sure that the rack is properly grounded.

Connect Power to the iBypass Switch

For power fault protection, the iBypass Switch has redundant power supplies. The

second power supply is available to support the ow of trafc to the monitoring
device in the event that the rst power supply becomes unavailable. If the rst

power supply is unavailable, the second power supply provides all power for the
iBypass Switch. Even if no power is available to the passive iBypass Switch,

network trafc ows uninterrupted.

Check the Installation

You have connected the iBypass Switch to the network, to the monitoring device
and to power. It should be functioning correctly now. Check the status of the fol­lowing:

• Check that at least one power LED is illuminated.

• Check the link status LEDs located on the front panel to verify that trafc is

passing through the switch.

• Check the display for utilization and peak information.

• Verify that the monitoring device is receiving trafc from the iBypass Switch.

• Verify that the Management Port is functional by typing the iBypass Switch's

IP address in your Web browser. Net Optics' Web Manager should appear. If it
does not, check the Management Port cables and connections and verify that the
Display option in the CLI is set to ON.

Reset Peak Rate Reset (toggle Yes/No) the rate of peak usage on Port A,

Port B, Port 1, Port 2 (separate control for each port). The

Peak Rate is a trafc measurement during peak time. The

Net Optics iBypass Web Manager will capture the highest
peak rate and time, and then display them in the Statistics
section.

Assume that these peaks occurred:
8:00 AM = 1%;
9:00 AM = 2%;
10:00 AM = 50%;
11:00 AM = 15%;
12:00 AM = 20%;

3:00 PM = 30%;
4:00 PM = 20%;
5:00 PM = 60%.

In the Status window, at 10 AM, 50% was the Peak Rate
and the display remained that way until 5 PM if no reset was
done. If a reset was done at 11 AM, then the Peak Rate
changed to 20% at noon, then 30% at 3 PM, then 40% at 2
PM, and then 60% at 5 PM.

Reset Statistics Reset (toggle YES/NO) the statistics of Port A, Port B, Port

1, Port 2 (separate control for each port).

Total Packets Total number of packets that have passed through the

a circled arrow appears next to the value to alert you to the
change; if polling produces the same total packet result
twice in a row, the circled arrow disappears.

iBypass Switches with Heartbeat

Field Description

Total Bytes Total number of bytes that have passed through the iBypass

unit since the last reset. When this value changes, a circled
arrow appears next to the value to alert you to the change;
if polling produces the same byte total twice in a row, the
circled arrow disappears.

Oversized Packets This function tracks the number of oversized packets since

the last reset. The Ethernet specication requires that no

packet be larger than 1518 bytes (including checksum).

Any packet that is larger than this is agged as an error and

discarded. These packets are also sometimes referred to
as “Jabbers”. Packets too big are almost always caused by
faulty hardware. The network adapter card on a link showing
a high rate of oversized packets should be replaced. Sup­port IEEE 802.1q

CRC Packets This function tracks the number of CRC errors since the last

reset. MAC Frame CRC errors are the most common. Ether­net packets are encapsulated in a MAC frame that contains
a preamble, and a post-envelope CRC check. The Ethernet
adapter on the sending station creates the preamble, inserts
the packet data (addressing, protocol, data, etc.), calculates
a CRC checksum and inserts it at the end of the packet. If
the receiving station determines that the checksum is incor­rect, the packet is assumed to be bogus and is discarded.

MAC frame CRC errors are typically caused by faulty
cabling. If the cabling connecting an Ethernet Adapter or
hub is faulty, the electric connection may be on and off
many times during a transmission. This on-and-off state can
interrupt parts of a transmission and damage the signal. If
the signal is interrupted partially during transmission, the
CRC checksum that was calculated by the network adapter

is longer valid and the packet is agged as a CRC error and

discarded.

CRC errors are common on a busy network, and a small

percentage does not reect a network problem. When the

percentage is large, or when a single station shows a larger
percent CRC errors, there is probably a problem.

Note: ____________________________________________________________________

The default values for Timeout are 1 ms on 10 GigaBit models and 1 second on other
models. Default Retry is 3 packets. With these settings, the iBypass Switch goes to Bypass
ON mode in 3x1 ms=3 ms (10 GigaBit models) if no Heartbeat packets are detected. If
customer equipment latency exceeds 3 ms, then the iBypass Switch will go into Bypass
ON mode before it detects the rst Heartbeat packet. Customers should change one or
both of the above default parameters to the higher number to avoid this behavior.

__________________________________________________________________________

Set Parameter Port Command

The <parameter> values for the "set parameter port" command for the IBP-HBCU3

are dened in the following table. The selection applies to all four ports—the

Network Ports and the Monitor Ports.

Note: ____________________________________________________________________

Enter <parameter> in decimal for the set parameter port command. The parameter
is displayed in hex in response to the show set command.
