Features
2.1 General
The EdgeSafe Bypass TAP (IBS) supports four operation modes: Inline, Bypass, Tap and
Linkdrop modes.
In Inline mode, the IBS diverts in-line network traffic to the attached in-line network system.
In Bypass mode, the IBS diverts in-line network traffic to the other network link only.
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 IBS disables the links on the network ports (NET0, NET1). The IBS
simulates switch / router cable disconnection.
The EdgeSafe Bypass TAP (IBS) 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 IBS detects the
heartbeat packet coming back it maintains the Inline mode state.
When the EdgeSafe Bypass TAP (IBS) does not detect the heartbeat packet from the Network
/ Monitor the IBS sets to Bypass. When the Network / Monitor appliance recovers, it
transmits the heartbeat packet back and the IBS sets from Bypass to Inline.
The IBS includes a "Double Safe" Bypass architecture. The Garland Technology "Double safe"
bypass architecture is based on two separate Bypass routing circuitries: An Active Bypass
circuitry and a Passive Bypass circuitry. If the internal active bypass routing circuitry fails, the
passive Bypass routing circuitry is activated.
The EdgeSafe Bypass TAP (IBS) can be configured via a management serial communication
port and via management Ethernet port using telnet, SSH or SNMP.
2.2 Bypass Modes
The EdgeSafe Bypass TAP (IBS) 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.
