R6100 AUTO BYPASS SWITCH Page 3of 27
2. Introduction
The R6100Auto Bypass Switch is a 1U rackmount, dual port RJ45 A/B switch that is designed to automatically
switch between a “normal” network path and a “bypass” or “failover” path for 10/100/1000 Ethernet network
environments. User configurable parameters control an auto-bypass switching function and an auto-recovery
switching function to allow the switch to be used in a variety of applications. For example, the Auto Bypass Switch
can be used with in-line network monitoring devices, Intrusion Prevention Systems, etc. to automatically remove these
devices from the network during maintenance or should they fail, while simultaneously providing a bypass path to
insure continued flow of traffic thru the network. To prevent “flapping” between a failed “normal” path, and the
bypass path connections, the auto recovery functioncan be disabled. This allows the problem in the normal path to be
corrected before sending a command to the R6100 to restore the normal network connections.
In order to be able to perform the auto bypass and auto recovery switching functions, the R6100 Auto Bypass Switch
issues ICMP echo request (PING) packets from an internal Ethernet node to any user configurable IP address on the
network. If the normal path connections go down for any reason, the R6100will no longer be able to PING the IP
address specified during configuration, and will automatically disconnect the normal path connections and switch to
the bypass/failover path connections. If auto recovery is enabled, the R6100 will automatically re-connect the normal
path connections when it is again able to PING the user specified IP address.
In addition to the PINGs used for auto bypass and auto recovery switching, the R6100can also be sent a command on
its serial RS232 interface or its Ethernet interface, to cause it to issue a single PING to any IP address on the network.
This PING command can be used to test network connectivity during initial installation or when troubleshooting
network problems.
As noted previously, the Auto Bypass Switch can automatically switch connection states using its auto bypass and
auto recovery switching functions. Or the user can remotely issue switch commands via the R6100 Ethernet interface
or RS232 serial interface. If using the Ethernet interface, three different options exist for remotely controlling the
R6100–the R6100supports telnet access, SNMP SET/GET commands via a proprietary MIB, or html access using
any web browser. Manual control of the switch is also provided by a momentary contact toggle switch on the front of
the unit. This manual toggle switch can be disabled by removing a front panel keylock switch on the R6100.
High reliability non-latching telecommunications relays are used in the R6100 Auto Bypass Switch. When the R6100
is powered OFF, these non-latching relays make a connection between the “BYPASS or A” ports and the “COMMON
or C” ports for each switching element within the Auto Bypass Switch. Thus for most applications, the bypass path
through the R6100will be from the COMMON ports to the “BYPASS or A” ports, and the normal path will be from
the COMMON ports to the “NORMAL or B” ports. With this configuration, should power to the R6100switch fail,
the bypass path will automatically be connected (the R6100switches to the BYPASS to COMMON connection state)
and the R6100 will remain in this state until power is restored. Once power is restored, the R6100 Auto Bypass Switch
can automatically reconnect the normal path (switch back to the NORMAL to COMMON connection state) if auto
recovery mode is enabled. Or the user can issue a switch command via the RS232 or Ethernet remote control
interface, or use the front panel toggle switch to restore the normal connection path.
The Auto Bypass Switch also has the ability to issue either SNMP traps, or UDP syslog messages. These messages
can be sent to one or more network administrator systems to provide notification when the R6100 changes connection
states either automatically (auto bypass switching or auto recovery switching) or via manual control (front panel
toggle switch or commands received on the RS232or Ethernet interfaces), and when certain other events occur.
To restrict access to the R6100 Auto Bypass Switch, each of the Ethernet interface options (SNMP, telnet,and web
browser) can be independently enabled/disabled, andif enabled can be configured to require a login password.
Additionally, user access can be restricted by IP address so only commands received from pre-defined “administrator”
IP addresses will be acknowledged and acted upon.

3. Configuration
The internal jumpers and DIP switches inside the R6100 Auto Bypass Switch have been pre-configured at the factory
and should not be changed from their default settings. For reference, the factory default settings are as follows:
jumpers W1 & W2 in the 2-3 position, SW1 positions 3, 4, & 6 ON, and SW2 positions 2-8 ON.
jumper W1 1-2 position = no SNMP module, serial RS232 only
2-3 position = SNMP module installed, Ethernet & serial RS232
jumper W2 1-2 position = no SNMP module, serial RS232 only
2-3 position = SNMP module installed, Ethernet & serial RS232
DIP SW1 positions 1 through 4 set the number of ports from 1 through 16.
positions 1 & 2 OFF, and positions 3 & 4 ON for 4 port operation
positions 1 & 3 OFF, and positions 2 & 4 ON for 6 port operation
positions 1, 2 & 3 OFF, and position 4 ON for 8 port operation
positions 1 –4 all OFF for 16 port operation
position 5 OFF (reserved, leave OFF)
position 6 OFF = latching switches, position 6 ON = non-latching switches
position 7 OFF (reserved, leave OFF)
position 8 OFF (reserved, leave OFF)
DIP SW2 positions 1 OFF, 2-8 ON (Rack Address 0x01)
There are, however, several parameters related to TCP/IP operations as well as the auto bypass and auto recovery
functions that must be initially configured in order to operate the R6100 Auto Bypass Switch. These parameters are
accessible using either the serial RS232 remote control interface or the Ethernet remote control interface. These
parameters include:
•IP address, subnet mask, and gateway address for the Ethernet remote control interface on the R6100 Auto
Bypass Switch (this interface also functions as the internal Ethernet node that acts as the “PING source” used
by the auto bypass and auto recovery switching functions). Note that the factory default values for these
parameters are 192.168.1.30, 255.255.255.0, and 192.168.1.1 respectively.
•IP address and MAC address of the external Ethernet node that the R6100Auto Bypass Switch is to monitor
in order to determine when to switch between the normal and the bypass paths. A value of 0.0.0.0 for the
monitor IP address disables the auto bypass and auto recovery switching functions.
•Monitor interval –this is the time interval between PINGs issued by the internal Ethernet node in the R6100,
measured in 100 msec increments. For example, if you want the R6100 Auto Bypass Switch to issue PINGs
every 1.5 seconds then set this value to 15. The valid range is 1 to 255 (0.1 seconds to 25.5 seconds). A value
of 0 disables the automatic bypass/recovery functions.
•Monitor fail count–this is the number of successive PING attempts that must fail before the R6100 Auto
Bypass Switch automatically switches to the bypass path and removes the normal connection path. The valid
range is 1 to 255. A value of 0 disables the automatic bypass/recoveryfunctions.
•Monitor ok count–this is the number of successive PING attempts that must succeed before the Auto
Bypass Switch automatically switches back to the normal path and removes the bypass connection path. The
valid range is 1 to 255. A value of 0 disables only the automatic recovery function–automatic bypass will
still operate. If auto recovery is disabled the user must manually switch back to the normal path via the front
panel toggle switch or by issuing a “set system B” command to the Auto Bypass Switch via the RS232 or
Ethernet remote control interface.
•Save –this command saves any changes that are made to the configuration parameters for the next startup. If
the Save command is not used, the R6100will revert back to the prior configuration settings the next time
power is cycled, or after receiving a Reset command.
•Reset –this command restarts the R6100Auto Bypass Switch. Any configuration changes that were not first
saved will be defaulted back to their prior settings.
For additional details regarding the commands used to set these parameters, see Section 7.

4. Installation
4.1 Find a location suitable for installing the R6100 Auto Bypass Switch, with access to AC power outlets and the
connections you intend to switch through the unit.
4.2 If you intend to use serial control, connect a serial cable to the DB9 RS232 console port. The data rate and
format is fixed at 9600 bps, no parity, 8 data bits, 1 stop bit, and no flow control. See Table 6.1 for the DB9
connector pin assignment.
4.3There are two pairs of RJ45 A/B switch elements within the Auto Bypass Switch. Connect RJ45 cables
between the R6100 and the devices/network connections that you intend to switch. The R6100 simultaneously
connects all 8 pins on each C (COMMON) port to either their respective “BYPASS or A” port, or to their
“NORMAL or B” port for both switching elements. Telecommunications relays are used to make these
connections between ports, which makes the R6100 completely transparent to data formats, rates, protocols,
etc. Note that the switch provides straight through connections. If your application requires a cross-over cable,
use only 1 cross-over cable in that path. Use a straight through cable on the other side of the switch. Non-
latching relays are used in the R6100 Auto Bypass Switch, which default to the “BYPASS or A” to
“COMMON or C” connection state when power fails or is removed from the switch. Thus the “BYPASS or A”
to “COMMON or C” connections are typically used for the bypass/failover path connections, and the
“NORMAL or B” to “COMMON or C” connections are used for the normal path connections.
For example, when used with an Intrusion Prevention System or similar devices, the two “BYPASS or A” ports
on the R6100 are typically connected together witha short patch cable. The “NORMAL or B” ports on the
R6100 are connected to the IN/OUT ports on the IPS. And the “COMMON or C” ports on the R6100 are used
to provide the connections between the firewall and the R6100, and between the R6100 and the first edge
router/switch on the network. Thus when in the bypass mode, data will flow between the firewall and one of the
“COMMON or C” ports, thru the associated “BYPASS or A” port to the second “BYPASS or A” port via the
short patch cable, and then out the second “COMMON or C” port to the edge router/switch. And when in the
normal mode, the data will flow between the firewall and the first “COMMON or C” ports, thru the associated
“NORMAL or B” port to the IPS, back from the IPS to the second “NORMAL or B” port, and then out the
second “COMMON or C” port to the edge router/switch. See figure 1 below for an example of this
configuration.

to prevent flapping.
NORMAL BYPASS

Market Central, Inc.
R6100 AUTO BYPASS SWITCH Page 6of 27
In a typical failover application where a redundant or backup connection is required, the user(s) would be
connected to one of the “COMMON or C” ports, with the normal network connection to the respective
“NORMAL or B” port, and the failover network connection to the respective “BYPASS or A” port. The Auto
Bypass Switch provides two separate A/B switching elements, thus a second group of users can be connected to
their own “normal” and “failover” network ports. However, if the auto bypass/recovery functions of the R6100
are used, both devices will be simultaneously switched between their normaland failover connections when the
auto bypass or the auto recovery switching functions occurs. See figure 2 for an example of a failover/backup
configuration with one A/B switching element being used.
Figure 2.
4.4 Connect a 100-240VAC power source to either power supply connector. If you are using redundant power,
connect a power source to both power supply connectors. The indicators PS1 and PS2 on the front of the unit
will indicate when each power supply is energized. The switch position LED indicators BYPASS (A) and
NORMAL (B) on the front of the unit will light depending on the position of the A/B switching elements
within the R6100. The BYPASS (A) LED lights when both switching elements in the Auto Bypass Switch are
in the “BYPASS or A” to “COMMON or C” connection state, and the NORMAL (B) LED lights when both
switching elements within the R6100 are in the “NORMAL or B” to “COMMON or C” connection state. If one
A/B switch element is in the “BYPASS or A” position and the other is in the “BORMAL or B” position,
neither LED will be lit (this would occur only if the user issues a “set port n” command that switches only one
of the switching elements).
4.5 Before you connect the Auto Bypass Switch’s Ethernet remote control port to your Ethernet network, you
should first configure the R6100’s TCP/IP related parameters because the default parameters may not work, or
could interfere with your network. See Section 3 for a list of the TCP/IP parameters that need to be configured,
and see section 7 for a detailed description of the commands used to configure these parameters.
4.6 Once the TCP/IP parameters have been configured, connect the NETWORK port on the Auto Bypass Switch to
your layer 2 switch, HUB, or router. If using the R6100’s auto bypass/recovery switching functions, this same
layer 2 switch/HUB/router should also be connected to the appropriate switch ports on the R6100 in order to
create the required normal and/or bypass paths through the R6100, and to allow the PING packets from the
internal Ethernet node on the R6100 to travel to the desired external Ethernet node on the user’s network. See
figures 1 & 2 above for examples of typical network connections to the R6100 Auto Bypass Switch.

R6100 AUTO BYPASS SWITCH Page 7of 27
In a typical IPS environment, the NETWORK port on the R6100 would be connected to an unused port on the
edge router/switch as noted in the example configuration in figure 1 above. To provide auto bypass switching,
the R6100 can be configured to use the firewall’s IP and MAC addresses for the monitor IP address and
monitor MAC address parameters. With this configuration, if the R6100 detects a problem thru the normal path
and the IPS to the firewall, it will automatically switch to the bypass path. The auto recovery switching
function is typically not used in this type of application, and would normally be disabled. This approach allows
the network security manager to verify that when a problem occurs in the normal path thru the IPS (causing the
R6100 to switch to the bypass path), that anyproblems related to the IPS and the normal path are resolved
before the IPS is reconnected to the network. Once these problems have been resolved, the network security
manager can then issue a “set system B” command to the R6100 to switch back to the normal path.
In a typical failover environment, the NETWORK port on the R6100 would be connected to a layer 2 switch or
HUB as described in the example configuration in figure 2 above. To provide auto failover/recovery, the R6100
can be configured to use the IP and MAC addresses of a device on the “normal” network for the monitor IP
address and monitor MAC address parameters. With this configuration, the auto bypass switching function will
cause the R6100 to automatically switch to the failover network if it detects a problem thru the normal path to
the device being monitored. And if the auto recovery switching function is enabled, it will cause the R6100 to
automatically switch back from the failover network connection to the normal network connection once the
normal network operation is restored (the R6100 is able to PING the device again on the normal network path).
When using the auto bypass and auto recovery features, the monitorip address and monitormac address
parameters can be configured to monitor connectivity to any device within, or outside of the user’s network
environment. The monitormac address has two modes of operation–it can be manually configured, or it can be
set to automatic mode. For automatic mode, simply set the monitormac address parameter to 00 00 00 00 00 00.
Then set the monitorip address parameter to the IP address of the device you want to PING in order to monitor
the normal network path connections. The R6100 will issue an ARP request to the gateway router to get the
appropriate MAC address it needs to use in the PING packet. Alternately, you can manually enter the
appropriate MAC address. If monitoring connectivity to a device on the same subnet as the R6100’s internal
Ethernet node, set the R6100’s monitorip address and monitormac address parameters to the IP address and
MAC address of the device being monitored. If monitoring connectivity to a device on a different
subnet/network than the R6100’s internal Ethernet node, set the R6100’s monitormac address parameter to the
MAC address of the gateway router on the R6100’s subnet, and set the monitorip address parameter to the IP
address of the device being monitored. This allows the PING packet issued by the R6100 to be routed through
the gateway router to the target device on a different subnet/network.
4.7 Once you have configured the TCP/IP parameters, you may also want to configure the R6100’s access control
related parameters. The R6100 has an internal http server that provides access to its command interface via any
web browser. This internal http server can be enabled or disabled. If enabled, a password can also be set, its
TCP/IP port number can be configured, and an inactivity timeout can be configured to prevent unauthorized
access. The R6100 also provides telnet access, and SNMP access to its command interface. These interfaces
also have additional configuration parameters to restrict unauthorized access. See section 7 for a complete
description of theses access control related commands.
4.8 After setting up the system and configuring the auto switching features, remote access features, and TCP/IP
parameters for your application, you need to save the configuration in non-volatile memory by using the SAVE
command. After saving new parameters, it is recommended that you cycle power or use the RESET command
to reboot the R6100 to insure that the newly saved parameters are activated.
5. Operation
Whenever the R6100 Auto Bypass Switch is powered OFF, or if power fails, the non-latching relays in the R6100 will
be in the “BYPASS or A” to “COMMON or C” connection state, connecting the devices/networks attached to the
BYPASS (A) ports to the COMMON (C) ports of both sets of A/B switching elements within the R6100. When power
is applied to the R6100, the appropriate power supply status indicators (PS1 and/or PS2) will light and the BYPASS
(A) LED indicator on the front of the unit will also light to show that the non-latching relays in the R6100 are in the

Market Central, Inc.
R6100 AUTO BYPASS SWITCH Page 8of 27
BYPASS (A) position. Both A/B switching elements in the R6100 will remain in the BYPASS (A) position until the
user manually changes switch states via command or via the front panel toggle switch, or if auto recovery switching is
enabled and the R6100 determines that the normal path is available.
5.1 Manual Switching
The R6100 Auto Bypass Switch can be switched (both sets of ports simultaneously) from the momentary toggle
switch located on the front of the unit. This switching action is enabled by the front panel keylock switch, which must
be in the position labeled ENABLE for manual switching via the toggle switch to occur. When switching using the
toggle switch, the switch position LED indicator will light to the appropriate state -BYPASS (A) or NORMAL (B).
Switching can also be accomplished by issuing a “set system”, a “set rack” or a “set port” command via the RS232
remote interface or the Ethernet remote interface on the R6100. The auto switching feature, if enabled, is affected
differently depending on whether a “system” command is issued, or if a “rack” or “port” command is issued. See
Section 5.2 for additional details. Note that the keylock switch does not affect switching via the RS232 or Ethernet
remote interfaces.
5.2 Serial RS232 Switching
The R6100 Auto Bypass Switch can be switched using commands over a serialcommunications line. The parameters
of the DB9 RS232 console port are fixed at 9600 baud, 8 data bits, no parity, 1 stop, and no flow control (commonly
abbreviated as 9600, 8, N, 1, NONE).
When the R6100 powers up, it will send a sign-on message followed by a prompt character “>” to your serial terminal
device. After each command, and any associated response from the unit, it will again issue a prompt character. For
systems where the console port is being commanded by software, the software should wait for this prompt character
before sending each command to the R6100.
It is possible to switch either or both sets of switch ports to the BYPASS (A) or NORMAL (B) connection state using
the appropriate serial commands. It is also possible to query the position of either or both sets of switch ports using
serial commands. The DB9 serial interface is NOT affected by the position of the front panel keylock switch –it will
act upon and respond to commands it receives even if the keylock switch is in the DISABLE position.
The Auto Bypass Switch is a specialized version of the R6100 switching system. The R6100 Auto Bypass Switch is a
single rack system, configured to use rack address 1. It has only two ports installed, port 3 and port 4. When the Auto-
Switch feature is enabled, the R6100 internally issues “set system” commands when auto switching to the Bypass path
during auto-failover, and when switching to the Normal path during auto-recovery. Even with Auto Switching
enabled, the user can still use the front panel toggle switch or issue a “set system”, a “set rack” or a “set port”
command to change the connection state of the R6100. The Auto Switching feature however, doesn’t recognize the
“set rack” or “set port” commands and will operate as though no change in connection state actually took place. For
example, if the user issues a “set rack 1 A” command, the R6100 will switch to “A”. If at some point in time after this
the Auto Switching feature detects that a path failure has occurred, it will internally issue a “set system A” command
and report that an auto switch change from B to A has occurred.

5.3 Ethernet Switching
Switching can also be accomplished by sending a “set system”, a “set rack” or a “set port” command to the R6100 via
its Ethernet remote interface. Note that the auto switching feature, if enabled, is affected differently depending on
whether a “system” command is received, or if a “rack” or “port” command is received. See Section 5.2 for additional

Market Central, Inc.
R6100 AUTO BYPASS SWITCH Page 10of 27
details.
In order to use the Ethernet NETWORK port, you must first configure the IPADDRESS, SUBNETMASK, and
GATEWAY address of the R6100 Auto Bypass Switch before connecting to your network (see section 6 for more
details). If desired, you can set login passwords or disable one or more of the Ethernet interfaces (SNMP, telnet, or
web browser) using the appropriate commands. You can also restrict access via the Ethernet interface so that only
commands received from pre-defined “ADMIN” IP addresses will be acknowledged and acted upon (see section 7 for

The R6100Auto Bypass Switch can be switched using SNMP commands over a TCP/IP Ethernet network. See the
MIB Path Summary in the appendix for a list of SNMP variables and their functions. The R6100 also supports telnet
access, and can be controlled via a telnet session using the same commands as used by the RS232 serial interface. The
R6100 also includes a built in http server that allows all of the commands that are available via the RS232 serial port
to be accessed via a web browser interface. See section 8 for adetailed description of this feature.
The Ethernet NETWORK port on the R6100 is 10base-T only. There are two status indicators which function as
follows. The LINK LED is on whenever the Ethernet network interface is ready for communication. This should
happen very shortly after power on, and will go out if the R6100 detects a problem with this interface. Note that it
does not indicate that a valid network connection is made to another device. The ACT LED will blink whenever the
R6100 receives a command from the network interface, when its internal Ethernet node issues a switch command
(auto bypass/recovery operation), or when a switching command is issued via the serial port.
6. Network Setup
To perform the initial setup of the Ethernet interface onthe R6100 you can use a serial terminal capable of 9600 baud,
no parity, 8 data bits, 1 stop bit, and no flow control. Connect this terminal to the DB9 console connector on the
R6100 using the pinout from table 6.1 below. Use a straight thru M/F cable toconnect to an IBM PC standard DB9
serial port. Table 6.1 –DB9 Pin Assignment

2RECEIVED DATA TO TERMINAL
3TRANSMITTED DATA FROM TERMINAL
5GROUND n/a
Apply power to the system once the serial cable is connected.
The R6100 will go thru its boot up process and when this process is complete you will see a sign-on message
displayed on the serial console, e.g.

At this point the R6100 is ready for the configuration changes necessary before you will be able to communicate with
the unit using TCP/IP. You will need to enter an IP address and subnet mask, gateway address, read and write SNMP
community names if using SNMP, or a web password for browser access. These parameters then need to be saved
into non-volatile memory, and the system will then need to be reset to allow it to reconfigure with the new settings.
Any time one or more of these parameters is changed; they must be saved followed by a system reset. The following
shows a typical setup session. Change the entered parameters to suit your application requirements. All the console
level commands available are described in detailin section 7.
