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

Interfaces

The following sections describe the interfaces on the OC-3 ATM SwitchProbe devices:

Network Interface Cards

The OC-3 ATM SwitchProbe device contains the following two network interface cards:

Ethernet—Interface 1. The default mode of this interface (manage) allows the SwitchProbe device to communicate on the network by exchanging (sending and receiving) commands with a management station. You can change the mode of the Ethernet interface using the Agent Configuration Utility. However, to maintain peak performance, Cisco Systems recommends that you maintain the interface in manage mode. For information about configuring network interfaces, see the Cisco SwitchProbe Installation and Configuration Guide.

: For information about the Agent Configuration Utility, see:
: 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:

ATM—Interface 3. This interface supports OC-3 multimode fiber only. The physical ATM interface consists of two interface cards—one card for a DTE connection, and one card for a DCE connection. Each ATM interface card contains an SC connector and three LEDs. The ATM interface operates in monitor mode only (tracking network traffic).

Peripheral Controller Card

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

Remote Port—Serial Line Internet Protocol (SLIP) port. This 9-pin, male, D-type connector supports RS-232 signals. The port specifications are listed in Table 2.

: The remote port can only be used 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

: To adjust the baud rate of the remote port, see the Cisco SwitchProbe Installation and Configuration Guide.

The console port is a serial DB-9 male connection. You can connect an ASCII data terminal to the console port and use the OC-3 ATM SwitchProbe device command line interface to configure the device IP address, gateway address, and subnet mask. You can also use an ASCII data terminal to display debug and boot messages or change configuration parameters. For more information, see the publication SwitchProbe Installation and Configuration Guide. To set the console port baud rate, see the next section, "DIP Switches (SW1)Configurable DIP switches (labeled SW1) between the console and remote ports used for adjusting the baud rate of the console port and setting the device's boot mode.".

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

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)—Configurable DIP switches (labeled SW1) between the console and remote ports used for adjusting the baud rate of the console port and setting the device's boot mode.

Switch 1—Specifies whether 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.

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	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 (default)
	3 = on 4 = on	Console port = 19200 bps

Note Cisco SwitchProbe devices have 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 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

The Ethernet interface card contains two LEDs, described in Table 4.

Table 4: Ethernet Interface LEDs

LED Position	LED Color	Status	Description
Left LED	Green	On Off	Link signal detected. No link signal detected or no cable attached.
Right LED	Amber	On Blinking Off	Heavy network traffic. Moderate network traffic. No network traffic.

Glossary of Terminology

Table 6 lists the terminology used in this document:

Table 6: Terminology Used in This Document

Term	Definition
AAL	ATM adaptation layer—Layer of the ATM protocol reference model that converts ATM cells into a format (such as packets) that can be read at a higher layer, and conversely converts higher layer information into ATM cells. There are several ATM adaptation layers (AAL 1 through AAL5). In local area ATM, AAL5 is the adaptation layer of choice for data transmission.
ATM	Asynchronous Transfer Mode---Connection-oriented, high-speed technology based on fixed-length cells that transmits data over a WAN or LAN.
CIP	Classical IP over ATM---Internet Engineering Task Force (IETF) specification that defines the implementation of traditional IP over ATM. CIP, defined in RFC 1577, exclusively targets TCP/IP at Level 3 of the OSI model.
LANE	LAN Emulation---ATM Forum specification that defines how legacy LANs can interoperate with ATM devices. LANE focuses on emulating Level 2 LAN protocols of the OSI model (Media Access Control [MAC] and Logical Link Control [LLC]).
MPOA	Multiprotocol over ATM---ATM Forum specification that defines the implementation of multiple network-layer protocols over ATM. Focuses on emulating all three OSI model network layer LAN protocols.
OC-3	Optical Carrier 3---ATM physical layer specification that defines the use of fiber-optic media for transmission at 155 Mbps.
STS-n	Synchronous Transport Signal---SONET1 standard for transmission over OC-n optical fiber by multiplexing level n STS-1 frames (where n is an integer).
UNI	User-Network Interface---Interface between an ATM end-device and a private ATM switch, or between a private ATM switch and a public-carrier ATM network.

ATM Statistics in the RMON MIB

The OC-3 ATM SwitchProbe device assembles ATM cells into AAL5 protocol data units (PDUs). The device converts these PDUs into Ethernet-format frames to allow existing Remote Monitoring (RMON and RMON2) functionality to be implemented. ATM-specific physical layer statistics (such as Cells, CallAttempts, and Calls) are mapped to certain etherStats objects in the Ethernet Statistics Group of the Ethernet RMON MIB. (See
Table 7.) The resulting MIB is a shadow of the Ethernet RMON MIB.

Table 7: ATM Statistics Information Mapped to Ethernet RMON MIB

ATM-Specific Information	Description	Mapped to (etherStats object of Ethernet Statistics Group in Ethernet RMON MIB)
Cells	Total number of error-free cells detected.	etherStatusUndersizePkts
CallAttempts	Number of call attempts detected on all signaled ATM connections.	etherStatsJabbers
Calls	Number of successfully established calls detected on all signaled ATM connections.	etherStatsFragments
F5OAMCells	Number of F5OAM (operations and maintenance) cells.	etherStatsOversizePkts
