You can also reset the device using the Reset Agent option of the Agent Configuration Utility. For more information about this option, see the chapter "Initializing a SwitchProbe Device" in the Cisco SwitchProbe Installation and Configuration Guide.

Interfaces

The following sections describe the interfaces on the E-3 ATM SwitchProbe device:

Network Interface Cards

E-3 ATM SwitchProbe devices contain the following two network interface cards (NICs).

Note The interface location is a logical representation, not always the physical slot location in the chassis.

Ethernet NIC (Interface 1)

The default mode of this interface (manage) allows the SwitchProbe device to communicate on the network. You can change the mode of the Ethernet interface using the Agent Configuration Utility.

Note To ensure optimum performance, Cisco Systems recommends that you maintain the interface in manage mode

For information about configuring network interfaces, see the chapter "Configuring SwitchProbe Devices" in the Cisco SwitchProbe Installation and Configuration Guide.

For information about the Agent Configuration Utility, see these sources of information:

The section "Configuring the E-3 ATM Device with the Agent Configuration Utility" of this document.
The chapter "Initializing a SwitchProbe Device" in the Cisco SwitchProbe Installation and Configuration Guide.

The Ethernet interface (interface 1) supports 10Base2 (Thinnet), 10Base5 (Thicknet), or 10BaseT unshielded twisted pair (UTP). The factory configuration is indicated on the front panel with an appropriate label. The connector for each topology is as follows:

15-pin D-type attachment unit interface (AUI) for 10Base5 (Thicknet)
BNC for 10Base2 (Thinnet)
RJ-45 jack for 10BaseT (UTP)

Interface 1 is designed to communicate with the TrafficDirector application in manage mode, but you can configure the interface to simultaneously track network traffic and communicate with the TrafficDirector application in manage and monitor mode.

For information about configuring network interfaces, see the chapter "Configuring SwitchProbe Devices" in the Cisco SwitchProbe Installation and Configuration Guide.

For information about the Agent Configuration Utility, see these sources of information:

The section "Configuring the E-3 ATM Device with the Agent Configuration Utility" of this document.
The chapter "Initializing a SwitchProbe Device" in the Cisco SwitchProbe Installation and Configuration Guide.

E-3 ATM NIC (Interface 3)

This interface supports E-3 only. The physical ATM interface has a BNC connector that attaches to the E-3 tap, and four LEDs. The ATM interface operates in monitor mode only (tracking network traffic).

PCC (Interface 2)

The Peripheral Controller Card (PCC), always designated as interface 2, has the following three external components:

Remote Port (SLIP Port)

This 9-pin, male, D-type connector supports RS-232 signals.

Table 2 shows the console and remote port specifications.

Table 2: Console and Remote Port Specifications

Port Setting	Specification
Line rate	9600 bps (default)
Line code	ASYNC
Line interface	EIA/TIA-232
No. of bits	8
No. of stop bits	1
Parity	None

You can only use the remote port to exchange management data to and from an attached device such as a management station or a modem. You must configure the remote port to manage mode. The remote port can be the secondary management port if communication to the primary management port is lost.

Note You cannot use the remote port to monitor a network segment.

To adjust the baud rate of the remote port, see the chapter "Physical Description" in the Cisco SwitchProbe Installation and Configuration Guide.

Console (Configuration) Port

The port has a 9-pin male, D-type connector that supports RS-232 signals. When you configure the device (set IP address, gateway address, network mask, and so on) using an ASCII terminal, you must connect that terminal to this port. For more information about configuring the device using an ASCII terminal, see the chapter "Initializing a SwitchProbe Device" in the Cisco SwitchProbe Installation and Configuration Guide.

Note You cannot use the console port to monitor a network segment.

Use a null-modem cable to connect the console port to the ASCII terminal. For a sample wiring diagram, see the appendix "Cable Pinouts" in the Cisco SwitchProbe Installation and Configuration Guide.

Note EIA/TIA-232 and EIA/TIA-530 were known as recommended standards RS-232 and RS-530 before acceptance as standards by the Electronic Industries Association (EIA) and Telecommunications Industry Association (TIA).

DIP Switches (SW1)

You use the configurable DIP switches (labeled SW1) between the console and remote ports to adjust the baud rate of the console port and set the boot mode of the device.

Switch 1—Determines if the device boots from flash memory or erasable programmable read-only memory (EPROM).
Switch 2—Not used.
Switches 3 and 4—Specifies the console port baud rate.

If the raised portion of the switch is to the left, the switch is on.
If the raised portion of the switch is to the right, the switch is off.

Table 3 shows the DIP switch settings.

Table 3: DIP Switch Settings

Switch	Setting	Result
1	Off (default) On	Boot from flash memory Boot from EPROM
2	Off (default)	Reserved
3, 4	3 = off 4 = off	Console port = 1200 bps
	3 = off 4 = on	Console port = 2400 bps
	3 = on (default) 4 = off (default)	Console port = 9600 bps
	3 = on 4 = on	Console port = 19200 bps

Note Cisco SwitchProbe devices ship with the latest version of agent firmware loaded in both EPROM and flash memory. If an updated version becomes available, you might need to upgrade the agent firmware. For information about updating the firmware, see the chapter "Configuring SwitchProbe Devices" in the Cisco SwitchProbe Installation and Configuration Guide.

Because SwitchProbe devices boot from flash memory by default, all upgraded agent firmware is written to flash memory. Regardless of any upgrade, the factory-installed, original version of agent firmware remains in the EPROM. Therefore, if a firmware upgrade fails, you can force the device to boot from the EPROM by setting DIP switch 1 to on. The agent will boot from the EPROM and use the original version of firmware.

If the flash becomes corrupted, the agent automatically boots from EPROM, regardless of the setting of DIP switch 1.

Ethernet Interface LEDs

Table 4 describes the LEDs on the Ethernet interface.

Connecting an E-3 ATM SwitchProbe Device to
a Network Segment

Note Before connecting an E-3 ATM SwitchProbe device to the network, you must configure it with an IP address, subnet mask, and default gateway address. For more information, see the chapter "Initializing a SwitchProbe Device" in the Cisco SwitchProbe Installation and Configuration Guide.

Before connecting this device to the network, note the following warnings.

Note To see the warnings in multiple languages, see the appendix "Translated Safety Warnings" in the Cisco SwitchProbe Installation and Configuration Guide.

Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first.

Warning This equipment is to be installed and maintained by service personnel only as defined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel.

Warning The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

To connect an E-3 ATM SwitchProbe device to the network segment, see the following sections:

Making a Connection to an Ethernet Interface

The Ethernet interface supports Thicknet, Thinnet, or unshielded twisted pair (UTP) cable types; the device is set to one of the three types when it is manufactured. A label in the lower portion of the device front panel indicates the factory-set configuration.

Table 6 describes the label and corresponding connection.

Table 6: Ethernet Interface Factory Settings

If the Label States...	You Connect
Configured for AUI	A Thicknet (10Base5) cable to the Thicknet connector.
Configured for BNC	A Thinnet (10Base2) cable to the Thinnet connector.
Configured for UTP	A UTP cable to the RJ-45 UTP connector.

Making a Connection to an E-3 ATM Interface

Connecting an E-3 ATM interface to a full-duplex network segment is a two-stage process:

Connect the E-3 tap to the E-3 ATM interface on the SwitchProbe device.
Connect two E-3 ATM devices to the E-3 tap (to accumulate statistics about data as it travels on the network segment).

Note The E-3 tap is a passive device that presents high impedance to the link. Therefore, you can connect and disconnect the E-3 ATM SwitchProbe device from the tap without disrupting the integrity of the link being monitored.

Connecting the E-3 Tap to the E-3 ATM SwitchProbe Device

To connect the E-3 tap to the E-3 ATM SwitchProbe device, see Figure 5 and follow these steps:

Step 1 Locate the 15-foot cable (with a male DB-15 connector at one end and a female DB-15 connector at the other end) that is shipped with the tap.

Step 2 Plug the female connector of this cable into port 1 on the E-3 ATM interface
(port 1 is the ATM port).

Step 3 Plug the other end of the 15-foot cable (the end with the male DB-15 connector) into the female DB-15 port of the E-3 tap.

Figure 5: E-3 Tap Connected to E-3 ATM Interface

Connecting the E-3 Tap to the Network Segment

To connect the E-3 tap to the network, see Figure 6 and follow these steps:

Step 1 Locate the two cables that connect one E-3 ATM switch, server, or router to another E-3 ATM switch, server, or router.

Step 2 Unplug these two cables from one of the two E-3 ATM devices.

Step 3 Plug the ends of these two cables into the two ports labeled IN on the E-3 tap.
(The device plugged into the two IN ports is the DTE device).

Step 4 Locate two six-foot cables (with BNC connectors at each end) that are shipped with the SwitchProbe device.

Step 5 Plug one end of each of these cables into the two ports labeled OUT on the
E-3 tap.

Step 6 Plug the remaining connector on each of these cables into the E-3 ATM device from which you unplugged cables in Step 2. (The device plugged into the two OUT ports on the tap is the DCE device.)

Step 7 See Figure 7 to confirm that the new cabling setup reestablished the connections you had previously.

Figure 6: E-3 Tap Connected to Network Segment

Figure 7: E-3 Tap Connection Points

Connecting the E-3 ATM SwitchProbe Device to a
Power Source

To connect the E-3 ATM SwitchProbe device to a power source, follow these steps:

Step 1 Using the AC power cord included with the device, connect one end of the cord to the power socket.

Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.

Step 2 Connect the other end of the AC power cord to a suitable power source.

Note Depending on the voltage applied from the power source, the power supply automatically switches to the appropriate condition.

Making Management Connections

You can connect a management device to the E-3 ATM SwitchProbe device in one of two ways:

Out-of-band—Through the SLIP port.
Side-band—Through the Ethernet port.

Making an Out-of-Band Management Connection

The E-3 ATM SwitchProbe device supports out-of-band management through the serial port (labeled Remote) using SLIP or through the Ethernet interface.

Using the SLIP Port

You can use the SLIP connection as a secondary connection through which you access all network statistics. The SLIP link is normally used as a backup link when the network is not operational or when the agent is not accessible.

Configuring the Active Ethernet Interface

To perform out-of-band management through the active Ethernet interface, follow these steps:

Step 1 Connect an Ethernet cable to the active Ethernet interface.

Step 2 Configure the interface mode to manage.

Making Side-Band Management Connections

The E-3 ATM SwitchProbe device supports side-band management (manage and monitor mode on the same interface) through the active Ethernet interface of the device.

To make a side-band connection, follow these steps:

Step 1 Connect an Ethernet cable to the active Ethernet interface.

Step 2 Configure the interface mode to manage and monitor.

Configuring the E-3 ATM SwitchProbe Device

The Cisco SwitchProbe Installation and Configuration Guide (shipped with all Cisco SwitchProbe devices) explains the basic configuration process. Read and follow the instructions in that guide to configure the agent firmware in your SwitchProbe device.

Toggle rawhdr_capture	Lets you include AAL 5 (ATM Adaptation Layer 5) header information in any data capture of the interface packets. To change the setting to its opposite value (on to off, or off to on), enter 8 and press Enter.
Toggle ATM_framing	The E-3 ATM interface is set to a default framing value of Physical Layer Convergence Protocol (PLCP). To toggle the framing standard to ATM-Direct, enter 11 and press Enter. You cannot select PLCP if the E3_format is set to G.832.
Toggle coset_mode	You can add a coset polynomial to a received HCS (Header Check Sum) octet before that octet is compared with a calculated result required by the ATM Forum's UNI specifications. The default is on (the interface adds the coset polynomial to the received HCS octet). To change the value, enter 14. The value toggles to its opposite value (for example, on to off).
Toggle scrambling_mode	Data that passes over an E-3 ATM segment can be scrambled or descrambled. The scrambling_mode setting of the interface should match the scrambling mode setting of the segment being monitored by the SwitchProbe device. The default is off (the interface does not receive scrambled data). If the value in the scrambling_mode field is on, the interface does receive unscrambled data. To change the value, enter 15 and press Enter. The value toggles to its opposite value (for example, off to on).
Toggle E3_format	The E-3 ATM interface is set to a default value of G.751. To toggle the framing standard to G.832, enter 16 and press Enter. To set the value to G.832, the ATM_framing value must be ATM_Direct.
Toggle Manage mode	The E-3 ATM interface is always in monitor mode, and this value is always off. You cannot change this setting.
Toggle Monitor mode	The E-3 ATM interface is always in monitor mode, and this value is always on. You cannot change this setting.

Configuring the E-3 ATM Device with Command-Line Objects
