1Introduction
EdgeSafe 40G Bypass Modular Network TAP is second generation of an active external Bypass TAP
that protects network integrity from network failures and network maintenance. The Garland
Technology intelligent Bypass TAP is a self-generating heartbeat and controls the network switch mode
of operation.
The Garland Technology M40GBP is a 1U host system which supports up to three modules. The 1U
host system can support mix of 40G Bypass module and dual rate 10G/1G Bypass modules. A 40G
module supports one Bypass segment per module. A dual rate 10G/1G Bypass module supports two
Bypass segment in a module.
The Garland Technology M40GBP supports 40 Gigabit Ethernet Multimode Fiber (40GBase-SR4) and
40 Gigabit Single mode fiber (40GBase-LR4) network standards. Each 40G Bypass module includes
two MPO / LC ports for network ports, and two QSFP+ ports for the attached in-line network system.
The Garland Technology M40GBP supports dual rate 10/1 Gigabit Ethernet Multimode Fiber
(10GBase-SR , 1000Base-SX) and 10/1 Gigabit Single mode fiber (10GBase-LR, 1000Base-LX)
network standards. Each 10G Bypass module Network includes four LC Duplex Monitor ports and four
SFP+ ports for the attached in-line network system.

2Features
2.1 General
The Garland Technology EdgeSafe 40G Bypass Modular Network TAP (M40GBP) supports
three modes of operations: Inline, Bypass, Tap and Linkdrop. In Inline mode, the M40GBP diverts
inline network traffic to attached in-line network system. In Bypass mode, the M40GBP does not divert
the traffic to the attached in-line network system and diverts it to other network link. In Tap mode,
incoming traffic in port NET0 is mirrored to port MON0 and incoming traffic in port NET1 is mirrored
to port MON1.In Linkdrop mode the M40GBP disables the links on the network ports (NET0, NET1).
The M40GBP simulates switch / router cable disconnection.
The M40GBP generates the heartbeat packets and transmits the heartbeat packet to the in-line Monitor /
Network appliance port, the Monitor Network appliance receives the heartbeat packets and transmits is
to its other port (bridges the heartbeat packet). The M40GBP detects back the heartbeat packet and
maintains the Inline mode.
The M40GBP sets to Bypass, Tap or Linkdrop when it does not receive back the heartbeat packet
from the Network / Monitor appliance. When the Network / Monitor appliance recovers, it transmits
back the heartbeat packet and the Intelligent switch sets to Inline. The M40GBP bypasses its Ethernet
Monitor ports on event of power failure, Link failure, in-line software application system hang or user
request.
The M40GBP includes Double Bypass Safe architecture. The Garland Technology Double Bypass safe
architecture is based on two Bypass routing circuitry: An Active Bypass circuitry and Passive Bypass
circuitry. If the internal active bypass routing circuitry fails, the passive Bypass routing circuitry is
activated.
The M40GBP can be configured using:
Simple CLI configuration management via a serial communication console port, Ethernet port
using Telnet or SSH.
Web interface management interface.
SNMP.
The Garland Technology M40GBP Bypass switch includes centralized management to all Bypass
segments in the box.
The M40GBP includes two redundant 90 –240 V AC power supply or two redundant -48 DC power
supply.

2.2 Bypass Modes
The M40GBP sets to Bypass /TAP /Linkdrop mode when one of the following events occurs:
Application failure (Heartbeat)
Monitor Link failure.
Manual Bypass.
Power failure or power off.

2.3 Application failure (Heartbeat)
The M40GBP continuously generates heartbeat packets to the in-line Monitor / Network appliance port,
the Monitor/ Network appliance receives heartbeat packets and transmits it to its other port (bridges the
heartbeat packet).
As long as the M40GBP detects the heartbeat packet is received from the Monitor/ Network appliance,
it will maintain the Normal / In-Line mode state.
In event of application failure ( including power failure of the Monitor /Network appliance ) the
heartbeat packets are not transmitted back by the Monitor / Network appliance and since the M40GBP
does not receive the heartbeat packet it sets to Active Bypass or TAP or Linkdrop mode according to
the predefined settings of the heartbeat expiration state.
During Active Bypass and TAP modes the network traffic continues to flow through the network ports
and is not diverted to the monitor ports. As soon as the Monitor / Network appliance recovers and starts
transmitting back the heartbeat packets, the M40GBP will set to Normal / In-Line mode after detecting
the heartbeat packets for period set by the "hb_holdtime" parameter.

2.4 Monitor Link failure
The M40GBP supports Monitor ports failure detection. In an event of Link failure on one of the monitor
ports, the M40GBP bypasses the Ethernet ports by switching to “Active Bypass” mode. The network
traffic continues to flow through the network ports and is not diverted to the monitor ports. When the
Monitor link is restored, it transmits back the heartbeat packet, the M40GBP will then set to Inline
mode state after detecting the heartbeat packets for period set by the "hb_holdtime" parameter.
The "hb_holdtime" parameter can be changed via the management port from its initial default mode.
2.5 Power Failure
The M40GBP supports Bypass on Power failure. In event of power loss the M40GBP bypasses the
Ethernet ports by switching to Passive Bypass Mode. The network traffic continues to flow through the
network ports and is not diverted to the monitor ports. When power is restored, the M40GBP will set to
Normal / Inline mode state after detecting the heartbeat packets for the period set by the "hb_holdtime"
parameter.
The "hb_holdtime" parameter can be change via management port from their initial default mode.
