Configuring ATM Accounting and ATM RMON

This chapter describes the ATM accounting and Remote Monitoring (RMON) features used with the ATM switch router.

Note   This chapter provides advanced configuration instructions for the Catalyst 8540 MSR, Catalyst 8510 MSR, and LightStream 1010 ATM switch routers. For complete descriptions of the commands mentioned in this chapter, refer to the ATM Switch Router Command Reference publication.

This chapter includes the following sections:

  • Configuring ATM Accounting
  • Configuring ATM RMON
    • Note   The ATM accounting and ATM RMON features both require a minimum of 32 MB of dynamic random access memory (DRAM) installed on the multiservice route 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 router:

ATM Accounting Overview

The ATM accounting feature provides accounting and billing services for virtual circuits (VCs) used on the ATM switch router. 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 router 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 that you can retrieve using 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 multiservice route 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.

Configuring 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 router.
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  Purpose 

atm accounting enable

Enables ATM accounting for the ATM switch router.

Displaying the ATM Accounting Configuration

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

Command  Purpose 

more system:running-config

Displays the ATM accounting status.

Enabling 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:

  Command  Purpose 
Step 1 

Switch(config)# interface atm card/subcard/port

Switch(config-if)#

Selects the interface to be configured.
Step 2 

Switch(config-line)# privilege level number

Configures the default privilege level.
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

Displaying the ATM Accounting Interface Configuration

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

Command  Purpose 

more system:running-config

Displays 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
Building configuration...

Current configuration:
!

<information deleted>

!
interface ATM1/0/3
 no keepalive
 atm accounting
!
<information deleted>

Configuring the ATM Accounting Selection Table

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

  Command  Purpose 
Step 1 

Switch(config)# atm accounting selection index

Switch(config-acct-sel)#

Specifies the ATM accounting selection index number and changes to accounting selection mode.
Step 2 

Switch(config-acct-sel)# default [connection-type | list]

Resets the ATM accounting selection table configuration to the default.
Step 3 

Switch(config-acct-sel)# connection-types [pvc | pvp | spvc-originator | spvc-target | spvp-originator | spvp-target | svc-in | svc-out | svp-in | svp-out]

Specifies the connection type(s) for which you want to collect accounting records.
Step 4 

Switch(config-acct-sel)# list hex-bitmap

Configures the list of ATM accounting MIB objects to collect.1
1 The MIB objects are listed in the ATM Accounting Information MIB publication.

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 accounting 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)
Examples

The following example shows how to change to ATM accounting selection configuration mode and add the SPVC originator connection type entry to selection entry 1:

Switch(config)# atm accounting selection 1
Switch(config-acct-sel)# connection-types spvc-originator

The following example shows how to change to ATM accounting selection configuration mode and reset the connection types for selection entry 1:

Switch(config)# atm accounting selection 1
Switch(config-acct-sel)# default list

The following example shows how to change to ATM accounting selection configuration mode and configure the selection list to include object number 20 (atmAcctngTransmitTrafficDescriptorParam1):

Switch(config)# atm accounting selection 1
Switch(config-acct-sel)# list 00001000

Displaying ATM Accounting Selection Configuration

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

Command  Purpose

Using 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  Purpose 
Step 1 

Switch(config)# access-list access-list-number {deny | permit} {source [source-wildcard] | any}

Defines a standard IP access list using a source address and wildcard or the any option default source 0.0.0.0 and source mask 255.255.255.255.
Step 2 

Switch(config)# tftp-server {atm-acct-active:acctng_file1 | atm-acct-ready:acctng_file1} ip-access-list

Allows TFTP to copy the ATM accounting file to an IP host in response to a read request.
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)# access-list 1 permit 10.1.1.1
Switch(config)# tftp-server atm-acct-ready:acctng_file1 1

For more information about access lists, see the "Filtering IP Packets at the IP Interfaces" section.

Configuring 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:

  Command  Purpose 
Step 1 

Switch(config)# atm accounting file acctng_file1

Configures the ATM accounting file and changes to accounting file configuration mode.
Step 2 

Switch(config)# remote-log [only] primary-host hostname1 tcp-port1 [alternate-host hostname2 tcp-port2]

Specifies 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 router'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

Displaying the Remote Logging Configuration

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

Command  Purpose 

show atm accounting

Displays the remote logging configuration.

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

Switch# show atm accounting
ATM Accounting Info:     AdminStatus - UP;      OperStatus : UP

Configuring ATM RMON

This section describes the process you use to configure ATM RMON on the ATM switch router. 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 of ATM switch router 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.

Configuring 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 Simple Network Management Protocol (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  Purpose 

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

Configures 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"

Displaying the ATM RMON Port Select Group

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

Command  Purpose 

show atm rmon stats number

Displays 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

Configuring 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, perform the following steps, beginning in global configuration mode:

  Command  Purpose 
Step 1 

Switch(config)# interface atm card/subcard/port

Switch(config-if)#

Selects the interface to be configured.
Step 2 

Switch(config-if)# atm rmon collect port_sel_group

Configures 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

Displaying the Interface Port Selection Group Configuration

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

Command  Purpose 

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

Displays 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
        ATM0/0/0        ATM0/0/2

Enabling ATM RMON 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  Purpose 

atm rmon enable

Enables ATM RMON.

Displaying the ATM RMON Configuration

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

Command  Purpose 

more system:running-config

Displays 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
Building configuration...

Configuring an RMON Event

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

Command  Purpose 

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

Configures 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

Displaying the Generated RMON Events

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

Command  Purpose 

show rmon events

Displays 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

Configuring 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  Purpose 

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

Configures 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"

Displaying the Generated RMON Alarms

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

Command  Purpose 

show rmon alarms events

Displays 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
