Features
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.
