Configuring Interface Types

This chapter describes how to explicitly configure ATM network interface types, rather than depending on Interim Local Management Interface (ILMI) autoconfiguration (which senses the peer interface type and configures the LightStream 1010 ATM switch interface appropriately).

The network configuration modifications described in this chapter are used to explicitly specify your ATM network operation. Because the LightStream 1010 offers true plug-and-play operation, most users might not need to perform any of these procedures. In some cases, however, the autoconfiguration of interfaces may not be desired.

The LightStream 1010 ATM Switch Command Reference (11.2) publication provides the complete syntax for every switch configuration command and describes the no form of each command.

Description of Example Network

The example network shown in Figure 8-1 is used to describe some standard ATM interface configuration tasks you might want to perform after completing the tasks described in the chapter "Initially Configuring the LightStream 1010 ATM Switch."

Figure 8-1: Example Network Configuration

The network configuration shown in Figure 8-1 is an example of a corporate campus ATM backbone network connecting three buildings with an ATM connection across the wide-area network (WAN) to a remote sales office.

The following examples describe a hypothetical task involved in configuration of the network shown in Figure 8-1:

Example Format

The configuration examples in this chapter use the following format:

Description of the network connection to be modified
Rationale for modification
Task list describing the task and the commands used to modify and monitor the switch
Description of syntax used with the command used to modify and monitor the switch
Example of command(s) used to modify initial configuration
Description and example of the commands used to confirm modification

Disable Autoconfiguration

Autoconfiguration is the feature that determines the type of interface every time an interface comes up initially.

Rationale:

You must disable the autoconfiguration feature on an interface before you configure the interface protocol, for example, if you want to configure the interface to be a User-to-Network Interface (UNI).

To disable autoconfiguration on an interface, use the following EXEC commands. Use the no form of the auto-configuration command to disable autoconfiguration:

Task Command

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

configure¹
[terminal]

Select the interface to be configured.

interface atm card/subcard/port [.vpt #]

Disable autoconfiguration on the interface.

no atm auto-configuration

¹This command is documented in the LightStream 1010 ATM Switch Command Reference (11.2) publication.

Task	Command
At the privileged EXEC prompt, enter configuration mode from the terminal.	configure¹ [terminal]
Select the interface to be configured.	interface atm card/subcard/port [.vpt #]
Disable autoconfiguration on the interface.	no atm auto-configuration

Example

The following example shows how to disable autoconfiguration on interface ATM 1/0/0:

Switch# config t

Enter configuration commands, one per line.  End with CNTL/Z. 
Switch(config)# interface atm 1/0/0

Switch(config-if)# no atm auto-configuration

Switch(config-if)#
%ATM-6-ILMINOAUTOCFG: ILMI(ATM1/0/0): Auto-configuration is disabled, current interface 
parameters will be used at next interface restart.
Switch(config-if)# ^Z

Switch#

Display Autoconfiguration

To show the interface autoconfiguration, use the following command:

Task Command

Show the ATM switch configuration.

show atm interface atm card/subcard/port

Task	Command
Show the ATM switch configuration.	show atm interface atm card/subcard/port

Example:

The following example shows how to display the autoconfiguration status of ATM interface 1/0/0 as disabled:

Switch# atm interface atm 1/0/0

Configure UNI Interfaces

The UNI specification defines communications between ATM end stations (such as workstations and routers) and ATM switches in private ATM networks.

To configure a UNI interface between the switch LS1010-2(HB-1) in the Headquarters building to the Cisco router C7000(HB-1) in the same building, use the atm uni command in interface configuration mode. See Figure 8-2 for a detail of this type of network connection.

Figure 8-2: Multiple Link UNI Example

To configure the UNI interface, use the following EXEC commands. Use the no form of these commands to disable the UNI interface:

Task Command

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

configure¹
[terminal]

Select the interface to be configured.

interface atm card/subcard/port

Disable autoconfiguration on the interface.

no atm auto-configuration

Configure the ATM UNI interface.

atm uni [side {network | user}]
[type {private | public}]
[version {3.0 | 3.1 | 4.0}]

¹This command is documented in the LightStream 1010 ATM Switch Command Reference (11.2) publication.

Task	Command
At the privileged EXEC prompt, enter configuration mode from the terminal.	configure¹ [terminal]
Select the interface to be configured.	interface atm card/subcard/port
Disable autoconfiguration on the interface.	no atm auto-configuration
Configure the ATM UNI interface.	atm uni [side {network \| user}] [type {private \| public}] [version {3.0 \| 3.1 \| 4.0}]

Note Whenever a change in the interface protocol (such as UNI, NNI, or IISP), side, or version is configured, ATM signaling and ILMI will be restarted on the interface. When ATM signaling is restarted, all switched virtual connections (SVCs) across the interface will be cleared; permanent virtual connections will not be affected.

Example

The following example shows how to disable autoconfiguration on ATM interface 0/1/0 and to configure the interface as the user side of a private UNI running version 4.0:

LS1010-1(HB-1)(config)# interface atm 0/1/0

LS1010-1(HB-1)(config-if)# no atm auto-configuration

LS1010-1(HB-1)(config-if)#
%ATM-6-ILMINOAUTOCFG: ILMI(ATM0/1/0): Auto-configuration is disabled, current interface 
parameters will be used at next interface restart.
LS1010-1(HB-1)(config-if)# atm uni side user type private version 4.0

LS1010-1(HB-1)(config-if)#
%ATM-5-ATMSOFTSTART: Restarting ATM signalling and ILMI on ATM0/1/0.

Configure a Public Network Tunnel Interface

This section describes configuring the DS3 public UNI ATM connection as a virtual path (VP) tunnel from the Headquarters building across the WAN to the Remote Sales building.

Note A VP tunnel is configured as a VP of a particular service category. Only virtual circuits (VCs) of that service category can transit the tunnel.

Figure 8-5 shows a detail of the example network being configured.

Figure 8-5: Public VP Tunnel Network Example

Rationale

Public DS3 carriers can interconnect switches using permanent VPs across their networks. To support signaling across the public network between switch LS1010-1(HB-1) in the Headquarters building and the Remote Sales building switch LS1010(SB-1), a VP tunnel must be configured.

ATM PVP and VP Tunnel Command Description

To configure a VP tunnel connection, use the following EXEC commands. Use the no form of these commands to disable the VP tunnel connection:

Task Command

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

configure¹
[terminal]

Optionally, configure the connection-traffic-table-row index for any nondefault index values.

atm connection-traffic-table-row [index row-index] cbr pcr rate [tolerance cell-count]

Select the physical interface to be configured.

interface atm card/subcard/port

Configure an interface permanent virtual path (PVP) leg.

atm pvp vpi [rx-cttr index] [tx-cttr index]

Change to configuration mode.

exit

Create a VP tunnel using a VPT number that matches the PVP leg virtual path identifier (VPI).

interface atm card/subcard/port.vpt #

¹This command is documented in the LightStream 1010 ATM Switch Command Reference (11.2) publication.

Task	Command
At the privileged EXEC prompt, enter configuration mode from the terminal.	configure¹ [terminal]

Configure a PVC to a VP Tunnel

To configure an endpoint of a permanent virtual circuit (PVC) to a previously created PVP tunnel, use the following EXEC commands. Use the no form of this command to disable the PVC:

Task Command

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

configure¹
[terminal]

Select the physical interface to be configured.

interface atm card/subcard/port

Configure the PVC with the VPI of the tunnel leg matching the tunnel VPT number.

atm pvc vpi vci [upc upc] [pd pd] [rx-cttr index] [tx-cttr index] interface atm card/subcard/port[.vpt #] vpi vci [upc upc]

¹This command is documented in the LightStream 1010 ATM Switch Command Reference (11.2) publication.

Task	Command
At the privileged EXEC prompt, enter configuration mode from the terminal.	configure¹ [terminal]
Select the physical interface to be configured.	interface atm card/subcard/port
Configure the PVC with the VPI of the tunnel leg matching the tunnel VPT number.	atm pvc vpi vci [upc upc] [pd pd] [rx-cttr index] [tx-cttr index] interface atm card/subcard/port[.vpt #] vpi vci [upc upc]

The following restrictions must apply to an endpoint of a PVC-to-PVP tunnel subinterface:

The VPI number of the tunnel leg of any PVC connection must match the VPT number of the tunnel.

The service class (for example, constant bit rate [CBR]), variable bit rate [VBR], unspecified bit rate [UBR], as specified by the connection-traffic-table-row [CTTR]) of any PVC connections must match the service class for the row(s) selected for the tunnel PVP.
For service classes other than UBR and available bit rate (ABR), the peak cell rates of all PVCs must be within the peak cell rate of the tunnel PVP. This setup requires new CTTR rows to be defined for CBR or VBR PVCs, with peak cell rates that are less than the intended tunnel PVP.

Example

The following example shows how to configure the example tunnel ATM1/0/0.99 with a UBR PVC from interface ATM 0/0/1 to the tunnel at ATM interface 1/0/0.99:

LS1010-1(HB-1)# configure t

Enter configuration commands, one per line.  End with CNTL/Z.
LS1010-1(HB-1)(config)# interface atm 0/0/1

LS1010-1(HB-1)(config-if)# atm pvc 0 50 interface atm 1/0/0.99 99 40

LS1010-1(HB-1)(config-if)# end

LS1010-1(HB-1)#

Display PVCs

To confirm the ATM virtual circuit interface configuration, use the following command:

Task Command

Show the ATM VC interface configuration.

show atm vc interface atm card/subcard/port

Task	Command
Show the ATM VC interface configuration.	show atm vc interface atm card/subcard/port

Example

The following example shows how to confirm the configuration of ATM subinterface 1/0/0.99 on switch LS1010-1(HB-1) located in the Headquarters building:
