Cisco Multiport T1/D or E1/D WAN SwitchProbe Configuration Note

Cisco Multiport T1/D or E1/D WAN SwitchProbe Configuration Note

This document describes how to connect and configure the Multiport T1/D or E1/D WAN SwitchProbe devices.

These devices are an extension of the existing Multiport T1/E1 WAN SwitchProbe device family, providing the same type of statistics about traffic flow across a WAN link.

However, unlike the Multiport T1/E1 WAN SwitchProbe devices—which connect between a router and a Data Service Unit/Channel Service Unit (DSU/CSU)—the Multiport T1/D or E1/D WAN SwitchProbe devices connect to the WAN link between the DSU/CSU and the WAN demarcation point. These devices provide a monitoring mechanism for WAN access devices such as routers or Frame Relay Access Devices (FRADs) with an integrated DSU/CSU.

The Multiport T1/D or E1/D WAN SwitchProbe devices use a passive, pass-through, active repeating T1/E1 tap to monitor T1 or E1 network activity.

The Multiport T1/D or E1/D WAN SwitchProbe devices are available in four models:

Interfaces

The following sections describe the interfaces on the Multiport T1/D or E1/D WAN SwitchProbe devices:

Network Interface Cards

The Multiport T1/D or E1/D WAN SwitchProbe devices contain the following two Network Interface Cards (NICs):

For more information, see the section "Multiport T1/D or E1/D WAN SwitchProbe Device Interfaces" in this document.

Peripheral Controller Card

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

  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.
  To adjust the baud rate of the remote port, see 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).
  To configure a SwitchProbe device (set IP address, subnet mask, and default gateway address) using an ASCII terminal, you must connect that terminal to the console port. For more information about configuring the SwitchProbe device through an ASCII terminal, see the initialization chapter in the Cisco SwitchProbe Installation and Configuration Guide.
  Use a null-modem cable to connect the console port to an ASCII terminal. A sample wiring diagram of a null-modem crossover cable is provided in the cable pinouts appendix in the Cisco SwitchProbe Installation and Configuration Guide.

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 contains two LEDs, described in Table 4.

This option allows you to select the DS0 units (time slots) of the selected E1 channel.

After you select this option, you are prompted to enter the particular time slots. Enter time slot information in one of four formats:

A single time slot (for example, 7)

Several time slots, each separated by a space (for example, 11 18 4)

A range of time slots, with low to high boundaries separated by a hyphen (for example, 3-15)

A combination of the preceding forms (for example, 3 15 11-13 18-22)

Change DS0 rate

Each DS0 can have a bandwidth rate of 64k (default), 56k, or 48k.

To change the DS0 bandwidth value, enter 4 and press Enter.

Three choices are displayed. Enter the desired bandwidth rate. The rate is case sensitive.

Change e1_code

The device is set to a default code standard of HDB3 (high-density, bipolar 3-zero).

To toggle the code to AMI (Alternate Mark Inversion), enter 5 and press Enter.

Change e1_framing

The device is set to a default framing value of crc_4 (cyclic redundancy check).

To toggle the framing standard to no_crc_4 (no cyclic redundancy check), enter 6 and press Enter.

Change_e1_mode

The device can have one of two modes:

  • CCS (Common Channel Signaling)—Used in a network with no voice traffic (slot 0 is used for framing data). This is the default.

  • CAS (Channel Associated Signaling)—Used in a network that has voice and data traffic (slot 0 is used for framing data; slot 16 is used for framing voice).

To toggle the e1_mode value (CCS/CAS), enter 7 and press Enter.

Change_data_invert

Data inversion is primarily used with AMI in most older CSUs for better noise tolerance. The default data invert setting is off.

To toggle this feature (on/off), enter 8 and press Enter.

To return to the main menu of the Agent Configuration Utility, enter 9 and press Enter. For more information about resetting the SwitchProbe agent, see the configuration chapter in the Cisco SwitchProbe Installation and Configuration Guide.

T1/D WAN Link Worksheet Instructions—Channel Mapping

The WAN network can consist of many time slots in many channels. The worksheet in Figure 22 is provided to help you map the channels/time slots of the network to be monitored. When complete, you can use this chart to assist you in entering the channel/time slot information required by the SwitchProbe device.

To complete the worksheet, follow these steps:

Step 1   Place an X in the appropriate time slot of the channel(s) on the network to be monitored.

For example, if the network is configured to use time slots 6, 8, and 21 of channel 4, place an X to the right of channel 4 in the 6, 8 and 21 time slots.

Step 2   Whenever you place an X in a time slot:
