Configuring ATM Accounting and ATM RMON

Note For a complete description of the commands mentioned in this chapter, refer to the LightStream 1010 ATM Switch and Catalyst 8510 MSR Command Reference publication.

Note The ATM accounting and ATM RMON features both require a minimum of 32 MB of dynamic random access memory (DRAM) installed on the processor. If you want to run both ATM accounting and ATM RMON features together you must have 64 MB of DRAM.

Configuring ATM Accounting

The following sections describe the process used to enable and configure the ATM accounting feature on the ATM switch:

ATM Accounting Overview

The ATM accounting feature provides accounting and billing services for virtual circuits (VCs) used on the ATM switch. You enable ATM accounting on an edge switch to monitor call setup and traffic activity. A specific interface can 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 connections that require monitoring for accounting and billing purposes.

Switching speeds and number of VCs supported by the ATM switch while monitoring virtual circuit use for accounting purposes can cause the amount of data to be gathered to reach the megabyte range. With such a large amount of data in the ATM accounting files, using traditional Simple Network Management Protocol (SNMP) methods of data retrieval is not feasible. You can store the collected accounting information in a file which you can retrieve via a file transfer protocol. SNMP provides 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 processor. One buffer is actively saving data, while the second is passive and ready to have its data either retrieved using Trivial File Transport Protocol (TFTP) or overwritten when the currently active file reaches its maximum capacity. Alternatively, the file can be written to a remotely connected PC over a TCP connection.

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 ATM switch.

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 in global configuration mode:

Command Task

atm accounting enable

Enable ATM accounting for the ATM switch.

Command	Task
atm accounting enable	Enable ATM accounting for the ATM switch.

Display the ATM Accounting Configuration

To display the ATM accounting status, use the following privileged EXEC command:

Command Task

more system:running-config

Display the ATM accounting status.

Command	Task
more system:running-config	Display the ATM accounting status.

Enable ATM Accounting on an Interface

After you enable ATM accounting, you must configure specific ingress or egress interfaces, usually on edge switches connected to the external network, to start gathering the ATM accounting data.

To enable ATM accounting on a specific interface, perform the following tasks, beginning in global configuration mode:

Step Command Task

1
interface atm card/subcard/port

Select the interface to be configured.

2
atm accounting

Enable ATM accounting on the selected interface.

Step	Command	Task
1	interface atm card/subcard/port	Select the interface to be configured.
2	atm accounting	Enable ATM accounting on the selected interface.

Example

The following example shows how to enable ATM accounting on ATM interface 1/0/3:

Switch(config)# interface atm 1/0/3

Switch(config-if)# atm accounting

Display the ATM Accounting Interface Configuration

To display the ATM accounting status, use the following privileged EXEC command:

Command Task

more system:running-config

Display the ATM accounting status.

Command	Task
more system:running-config	Display the ATM accounting status.

Example

The following display shows that ATM accounting is enabled on ATM interface 1/0/3:

Switch# more system:running-config

Configure the ATM Accounting Selection Table

The ATM accounting selection table determines the connection data to be gathered from the ATM switch. To configure the ATM accounting selection entries, perform the following tasks, beginning in global configuration mode:

Step Command Task

1
atm accounting selection index

Specify the ATM accounting selection index number and change to accounting selection mode.

2
default [connection-type | list]

Reset the ATM accounting selection table configuration to the default.

3
connection-types [pvc | pvp | spvc-originator | spvc-target | spvp-originator | spvp-target | svc-in | svc-out | svp-in | svp-out]

Specify the connection type(s) for which you want to collect accounting records.

4
list hexadecimal_number

Configure the list of ATM accounting MIB objects to collect¹.

¹The MIB objects are listed in the ATM Accounting Information MIB publication.

Step	Command	Task
1	atm accounting selection index	Specify the ATM accounting selection index number and change to accounting selection mode.
2	default [connection-type \| list]	Reset the ATM accounting selection table configuration to the default.
3	connection-types [pvc \| pvp \| spvc-originator \| spvc-target \| spvp-originator \| spvp-target \| svc-in \| svc-out \| svp-in \| svp-out]	Specify the connection type(s) for which you want to collect accounting records.
4	list hexadecimal_number	Configure the list of ATM accounting MIB objects to collect¹.

The atm accounting selection 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.

Some features of the ATM selection table configuration include:

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 nonexistent file, in which case the entry is considered inactive.
One selection entry can apply to more than one type of VC (or example, SVC and PVC).
If you modify a selection entry list, 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)
--- atmAcctngCallingPartySubAddress (object number 31)
--- atmAcctngCalledPartySubAddress (object number 32)
--- atmAcctngRecordCrc16 (object number 33)

Use TFTP to Copy the ATM Accounting File

After the ATM accounting file is written to DRAM, you must configure TFTP to allow network requests to copy the accounting information to a host for processing. To do this, use the following command in global configuration mode:

Command Task

tftp-server atm-accounting acctng_file1 ip-access-list

Use TFTP to copy the ATM accounting file to an IP host.

Command	Task
tftp-server atm-accounting acctng_file1 ip-access-list	Use TFTP to copy the ATM accounting file to an IP host.

Example

The following example shows how to allow TFTP service to copy the ATM accounting file acctng_file1 to the IP access list of requesting host number 1:

Switch(config)# tftp-server atm-accounting acctng_file1 1

Configure Remote Logging of ATM Accounting Records

You can collect ATM accounting records to a remotely connected PC or UNIX workstation. You can use this method in place of, or in addition, to collecting ATM accounting records as a file into the switch's memory.

The remote logging method requires a server daemon to be running on a PC or a UNIX workstation that is reachable from the switch using IP. The server daemon listens to the TCP port specified in the switch side remote logging configuration. When the ATM accounting process on the switch sends a TCP connect request, the daemon accepts the connection. After connection has been established, the switch side ATM accounting process sends accounting records, as they are created, to the remote host. The remote host then receives the records and stores them in a local file. The collected ATM accounting records are in ASN1 format. The first record contains the format of the following records.

To configure remote logging, perform the following steps in global configuration mode:

Step Command Task

1

atm accounting file filename

Configure the ATM accounting file and change to accounting file configuration mode.

2

remote-log [only] primary-host hostname1 tcp-port1 [alternate-host hostname2 tcp-port2]

Specify the main and optional backup hostname or IP address and TCP port number.

Step	Command	Task
1	atm accounting file filename	Configure the ATM accounting file and change to accounting file configuration mode.
2	remote-log [only] primary-host hostname1 tcp-port1 [alternate-host hostname2 tcp-port2]	Specify the main and optional backup hostname or IP address and TCP port number.

The PC or workstation configured as backup takes over collection of ATM accounting records if the primary fails. Using the keyword only causes only remote logging to be performed, freeing the ATM switch's memory for other purposes.

Example

The following example shows how to configure remote logging to a PC named eagle on port 2001, with port 2002 as a backup:

Switch(config)# atm accounting file acctng_file1

Switch(config-acct-file)# remote-log primary-host eagle 2001 alternate-host eagle 2002

Display the Remote Logging Configuration

To display the remote logging configuration, use the following privileged EXEC command:

Command Task

show atm accounting

Display the remote logging configuration.

Command	Task
show atm accounting	Display the remote logging configuration.

The following example shows the remote logging configuration using the show atm accounting EXEC command:

Switch# show atm accounting

Configuring ATM RMON

This section describes the process you use to configure ATM RMON on the ATM switch. The following sections describe the process:

RMON Overview

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

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

The ATM-RMON counter uses the per-VC counters already maintained in the hardware and polled by the 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 processing requirements for ATM-RMON, and allows collecting statistics on many or all the ATM 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 ports.

Figure 14-3: ATM RMON Port Select Group Examples

An active port select group must be defined before any data collection can begin. You can use the command-line interface (CLI) and SNMP modules to configure and access port select group structures.

To configure an RMON port selection group, use the following command in global configuration mode:

Command Task

atm rmon portselgrp number [descr string | host-prio number | host-scope number |
matrix-prio number | matrix-scope number | maxhost number | maxmatrix | nostats |
owner string]

Configure the ATM RMON port selection group.

Command	Task
atm rmon portselgrp number [descr string \| host-prio number \| host-scope number \| matrix-prio number \| matrix-scope number \| maxhost number \| maxmatrix \| nostats \| owner string]	Configure the ATM RMON port selection group.

Example

The following example shows how to configure port selection group 7 with the a maximum host count of 500, maximum matrix count of 2000, host priority of 1, and owner name "nms 3".

Switch(config)# atm rmon portselgrp 7 maxhost 500 maxmatrix 2000 host-prio 1 owner "nms 
3"

Display the ATM RMON Port Select Group

To display the ATM RMON port select group statistics, use the following EXEC command:

Command Task

show atm rmon stats number

Display the ATM RMON port select group statistics.

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

Example

The following example shows how to display the configuration of port selection group 3 using the show atm rmon stats command from 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

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.

To configure an interface to an ATM RMON port selection group, use the following commands, beginning in global configuration mode:

Command Task

interface atm card/subcard/port

Select the interface to be configured.

atm rmon collect port_sel_group

Configure the interface to an ATM RMON port selection group.

Command	Task
interface atm card/subcard/port	Select the interface to be configured.
atm rmon collect port_sel_group	Configure the interface to an ATM RMON port selection group.

Example

The following example shows how to configure ATM interface 0/1/3 to ATM RMON port selection group 6:

Switch(config)# interface atm 0/1/3

Switch(config-if)# atm rmon collect 6

Display the Interface Port Selection Group Configuration

To display the ATM RMON port configuration status, use the following EXEC command:

Command Task

show atm rmon {host port_sel_group |
matrix port_sel_group | stats port_sel_group |
status}

Display the interface port selection group configuration.

Command	Task
show atm rmon {host port_sel_group \| matrix port_sel_group \| stats port_sel_group \| status}	Display the interface port selection group configuration.

Examples

The following example shows how to display the ATM RMON host configuration for port selection group 6 using the show atm rmon host command from user EXEC mode:

Switch# show atm rmon host 6

PortSelGrp: 6   Collection: Enabled     Drops: 0

The following example shows how to display the ATM RMON matrix configuration for port selection group 6 using the show atm rmon matrix command from user EXEC mode:

Switch# show atm rmon matrix 6

PortSelGrp: 6   Collection: Enabled     Drops: 0

The following example shows how to display the ATM RMON statistics configuration for port selection group 6 using the show atm rmon stats command from user EXEC mode:

Switch# show atm rmon stats 6

PortSelGrp: 6   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

The following example shows how to display the ATM RMON status for all port selection groups using the show atm rmon status command from user EXEC mode:

Switch# show atm rmon status

PortSelGrp: 1 Status: Enabled  Hosts:  4/no-max  Matrix:  4/no-max

Enable Data Collection

Use the atm rmon enable command to start ATM RMON data collection.

Note If you disable ATM RMON the configuration remains but becomes inactive (similar to using the shutdown command on an interface).

To enable ATM RMON data collection, use the following command in global configuration mode:

Command Task

atm rmon enable

Enable ATM RMON.

Command	Task
atm rmon enable	Enable ATM RMON.

Display the ATM RMON Configuration

To display the ATM RMON configuration, use the following privileged EXEC command:

Command Task

more system:running-config

Display the ATM RMON configuration.

Command	Task
more system:running-config	Display the ATM RMON configuration.

Example

The following example shows the ATM RMON configuration using the more system:running-config privileged EXEC command:

Switch# more system:running-config

Configure an RMON Event

To configure an RMON event being generated, use the following command in global configuration mode:

Command Task

rmon event number [log] [trap community] [description string] [owner string]

Configure an RMON event.

Command	Task
rmon event number [log] [trap community] [description string] [owner string]	Configure an RMON event.

Example

The following example shows how to configure a generated RMON event with an assigned name, description string, owner, and SNMP trap with community string:

Switch(config)# rmon event 1 description test owner nms_3 trap test

Display the Generated RMON Events

To display the generated RMON events, use the following EXEC command:

Command Task

show rmon events

Display generated RMON events.

Example

The following example shows the RMON events generated using the show rmon events EXEC command:

Switch# show rmon events

Event 1 is active, owned by nms_3
 Description is test
 Event firing causes trap to community test, last fired 00:00:00

Configure an RMON Alarm

You can configure RMON alarm generation if any of the configured parameters are met.

Note Refer to the Configuration Fundamentals Configuration Guide for general SNMP RMON configuration information.

To configure RMON alarms, use the following command in global configuration mode:

Command Task

rmon alarm number variable interval {delta | absolute} rising-threshold value [event-number] falling-threshold value [event-number] [owner string]

Configure the ATM RMON alarm.

Example

The following example shows how to configure RMON alarm number 1 to generate an alarm under the following conditions:

If the MIB atmHostHCCells exceed 500
If each sample, in absolute mode, shows:
- Rising threshold exceeding 10,000
- Falling threshold falling below 1000
The RMON alarm number 1 sends the alarm to the owner "nms 3"

Switch(config)# rmon alarm 1 atmHostInHCCells 500 absolute rising-threshold 10000 falling-threshold 1000 owner "nms 3"

Display the Generated RMON Alarms

To display the RMON alarm event, use the following EXEC command:

Command Task

show rmon alarms events

Display RMON alarms.

Example

The following example shows the RMON alarms and events using the show rmon alarms events EXEC command:

Switch# show rmon alarms events

Event 1 is active, owned by nms 3
 Description is test
 Event firing causes trap to community test, last fired 00:00:00
Alarm table is empty
