Configuring ATM Accounting and ATM RMON

This chapter describes the ATM accounting and Remote Monitoring (RMON) features used with the LightStream 1010 ATM switch, and includes the following sections:

Note 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 both require a minimum of 32 MB of dynamic random access memory (DRAM) installed on the ASP. 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 in the LightStream 1010 ATM switch:

ATM Accounting Overview

The ATM accounting feature provides accounting and billing services for virtual circuits (VCs) used on the LightStream 1010 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 15-1 shows a typical ATM accounting environment.

Figure 15-1: 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 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. 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 15-2 shows an interface, filtering, and file configuration example.

Figure 15-2: Interface and File Management for ATM Accounting

A file used for data collection actually corresponds to two memory buffers on the ASP. 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. 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.

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 switch.

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

Display the ATM Accounting Configuration

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

Command Task

show running-config

Display the ATM accounting status.

Command	Task
show 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

show running-config

Display the ATM accounting status.

Command	Task
show running-config	Display the ATM accounting status.

Example

The following display from the show running-config privileged EXEC command shows that ATM accounting is enabled on ATM interface 1/0/3:

Switch# show running-config
Building configuration...
 
Current configuration:
!
 
<Information Deleted>
 
!
interface ATM1/0/3
 no keepalive
 atm accounting
!
--More--
!
<information deleted>

Configure the ATM Accounting Selection Table

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

Step Command Task

1
atm accounting selection 1

Configure 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]

Configure the accounting connection type(s).

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 1	Configure 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]	Configure the accounting connection type(s).
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 nonexistant 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 filename ip_access_num

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

Command	Task
tftp-server atm-accounting filename ip_access_num	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

Configuring ATM RMON

This section describes the process you use to configure ATM RMON on the LightStream 1010 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 CPU requirements for ATM-RMON, and allows collecting 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 15-3, agent 1 has a port selection group 1 made up of ports.

Figure 15-3: 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 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}

Configure the ATM RMON port selection group.

Command	Task
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}	Configure the ATM RMON port selection group.

Example

The following example shows how to configure port selection group 7 with the following:

Maximum host count of 500
Maximum matrix count of 2000
Host priority of 1
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 group_number

Display the ATM RMON port select group statistics.

Command	Task
show atm rmon stats group_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

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
        ATM0/0/0        ATM0/0/2

Configure an RMON Event

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

Command Task

rmon event number { description name |
log [description name | owner name |
trap community_string] | owner name |
trap community_string}

Configure an RMON event.

Command	Task
rmon event number { description name \| log [description name \| owner name \| trap community_string] \| owner name \| trap community_string}	Configure an RMON event.

Example

The following example shows how to configure a generated RMON event:

Named 1
Description string test
Owner "nms 3"
SNMP trap with the community string test

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.

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 See the section "Configuring SNMP RMON Support" in the chapter "Initially Configuring the LightStream 1010 ATM Switch" for general SNMP RMON configuration information.

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

Command Task

rmon alarm number mib_object interval {absolute rising-threshold value falling-threshold value owner name |
delta rising-threshold value falling-threshold value owner name}

Configure the ATM RMON alarm.

Command	Task
rmon alarm number mib_object interval {absolute rising-threshold value falling-threshold value owner name \| delta rising-threshold value falling-threshold value owner name}	Configure the ATM RMON alarm.

Example

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

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
