Configuring ATM Accounting and ATM RMON

This chapter describes the ATM accounting and ATM Remote Monitoring (RMON) features used with the LightStream 1010 ATM switch. This chapter is separated into the following sections:

For a complete description of the commands mentioned in this chapter, refer to the LightStream 1010 ATM Switch Command Reference publication.

Note The ATM accounting and ATM RMON features are available with LightStream 1010 ATM switch Cisco IOS software Release 11.2(5) or later.

Configure ATM Accounting

This section describes the process needed to enable and configure the ATM accounting feature in the LightStream 1010 ATM switch. The following sections describe the process:

The ATM accounting feature provides accounting and billing services for virtual circuits (VCs) used on the LightStream 1010 ATM switch. ATM accounting is typically enabled on an edge switch to monitor call setup and traffic activity. A specific interface might be configured to monitor either incoming or outgoing or incoming and outgoing VC use. Figure 14-1 shows a typical ATM accounting environment.

Figure 14-1: ATM Accounting Environment

The edge switches, connected to the exterior internet, are typical connections requiring monitoring for accounting and billing purposes.

Switching speeds and number of VCs supported by the LightStream 1010 ATM switch while monitoring virtual circuit use for accounting purposes can cause the amount of data to be gathered to reach the megabyte range. Because the data gathered can be so large, using traditional Simple Network Management Protocol (SNMP) methods of data retrieval is not feasible. A better method is to store the collected accounting information in a file which can subsequently be retrieved via a file transfer protocol. SNMP is used to provide management control of the selection and collection of accounting data. Figure 14-2 shows an interface, filtering, and file configuration example.

Figure 14-2: Interface and File Management for ATM Accounting

A file used for data collection actually corresponds to two memory buffers on the ATM Switch Processor (ASP). One buffer is actively saving data, while the second one is passive and ready to have its data either retrieved using the Trivial File Transport Protocol (TFTP) or overwritten when the currently active file reaches its maximum capacity. Using TFTP to download the file is the same process used to download Cisco IOS images and configuration files from the switch Flash memory to a host.

Configure Global ATM Accounting

The ATM accounting feature must be enabled to start gathering ATM accounting virtual circuit call setup and use data. The ATM accounting feature runs in the background and captures configured accounting data for VC changes such as calling party, called party, or start time and connection type information for specific interfaces to a file.

Caution Enabling ATM accounting could slow the basic operation of the LightStream 1010 ATM switch.

To enable or disable the ATM accounting feature for the entire switch, use the atm accounting command.

Note Even when ATM accounting is disabled globally, other ATM accounting commands, both global and for individual interfaces, remain in the configuration file.

To enable the ATM accounting feature, use the following command. Use the no form of this command to disable.

This command creates or modifies an entry in the selection table by specifying the fields of the entry.

Note A default selection entry is automatically configured during initial startup and cannot be deleted.

Following are some features of the ATM selection table configuration:

An entry in the selection table points to a data collection file.
A selection entry cannot be deleted when data collection is active.
A selection entry can point to a non-existent file, in which case the entry is considered inactive.
One selection entry can apply to more than one type of VC (For example, SVC, PVC).
If a selection entry list is modified, the new value is used the next time the data collection cycle begins, for example, the next time the ATM accounting collection file swap occurs.

Note The following ATM accounting MIB objects are not supported:
- atmAcctngTransmittedClp0Cells (object number 16)
- atmAcctngReceivedClp0Cells (object number 18)

Switch(config)#

Configure ATM RMON

This section describes the process needed to configure ATM Remote Monitoring (RMON) on the LightStream 1010 ATM switch. The following sections describe the process:

Overview of RMON

The ATM RMON feature allows you to monitor network traffic for such reasons as fault monitoring or capacity planning. The ATM RMON feature is an extension of existing, well-known RMON standard and provides high-level per-host and per-conversation statistics in a standards-track MIB similar to the following existing RMON MIBs:

RMON-1 MIB-RFC 1757
RMON-2 MIB-RFC 2021 and 2074

The ATM-RMON counter uses the per-VC counters which are already maintained in the hardware and polled by software. The ATM RMON agent can report cell traffic statistics by monitoring connection management activity. At connection setup and release time, some ATM-RMON bookkeeping code is executed. The amount of information varies, depending on the ATM RMON configuration. The ATM-RMON bookkeeping capability significantly reduces the CPU requirements for ATM-RMON, and makes it possible to collect statistics on many or all the switch ports at once.

The ATM-RMON agent uses the 64-bit version of each cell counter if 64-bit counter support is present in the SNMP master-agent library.

Configure Port Select Groups

Previously, RMON allowed collection of connection information on a per interface basis only. ATM RMON allows a group of ports to be configured as an aggregate. The port select group defines this collection unit used by the ATM RMON agent to gather host and matrix connection data. For example, in Figure 14-3, agent 1 has a port selection group 1 made up of three ports.

Figure 14-3: ATM RMON Port Select Group Examples

An active port select group must be defined before any data collection can actually begin. The command-line interface (CLI) and SNMP modules are used to configure and access port select group structures, although infrequently.

Use the atm rmon portselgrp command to configure an RMON port selection group.

To configure an RMON port selection group in EXEC configuration mode, use the following command. Use the no form of the atm rmon portselgrp command to disable:

Task Command

At the privileged EXEC prompt, enter configuration mode from the terminal.

configure ¹
[terminal]

Configure the ATM RMON port selection group.

atm rmon portselgrp number {
descr label |
host-prio value_1-3 |
host-scope value_1-3 |
matrix-prio value_1-3 |
matrix-scope value_1-3 |
maxhost number |
maxmatrix number |
nostats [ label | value_1-3 | value_1-3 | value_1-3 | value_1-3 | number | number | owner ] |
owner name }

¹This command is documented in the LightStream 1010 ATM Switch Command Reference publication.

Task	Command
At the privileged EXEC prompt, enter configuration mode from the terminal.	configure ¹ [terminal]
Configure the ATM RMON port selection group.	atm rmon portselgrp number { descr label \| host-prio value_1-3 \| host-scope value_1-3 \| matrix-prio value_1-3 \| matrix-scope value_1-3 \| maxhost number \| maxmatrix number \| nostats [ label \| value_1-3 \| value_1-3 \| value_1-3 \| value_1-3 \| number \| number \| owner ] \| owner name }

Example

The following example configures port selection group 7 with the following:

maximum host count of 500
maximum matrix count of 2000
host priority of 1
the owner name "nms 3"

Switch#config terminal

Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#atm rmon portselgrp 7 maxhost 500 maxmatrix 2000 host-prio 1 owner "nms 3"

Switch(config)#

Display ATM RMON Port Select Group

Use the show atm rmon stats command to display the ATM RMON port select group statistics.

To display the ATM RMON port select group statistics, perform the following task in user EXEC mode:

Task Command

Display the ATM RMON port select group statistics.

show atm rmon stats group_number

Task	Command
Display the ATM RMON port select group statistics.	show atm rmon stats group_number

Example

The following example displays the configuration of port selection group 3 using the show atm rmon stats command from user EXEC mode:

Switch#show atm rmon stats 3

PortSelGrp: 3   Collection: Enabled     Drops: 0
  CBR/VBR: calls: 0/0  cells: 0 connTime: 0 days 00:00:00
  ABR/UBR: calls: 0/0  cells: 0 connTime: 0 days 00:00:00
Switch#

Configure Interfaces into a Port Select Group

Before the port selection group can begin gathering host and matrix connection information, an interface or group of interfaces must be added to the port selection group.

Use the atm rmon collect interface command to add an individual interface to a port selection group.

To configure an interface to an ATM RMON port selection group in EXEC configuration mode, use the following commands. Use the no form of the atm rmon interface command to disable ATM RMON collection on that interface:

Task Command

At the privileged EXEC prompt, enter configuration mode from the terminal.
