Software Release 51.1(5)

This section contains usage guidelines and restrictions and provides the software modifications and caveats for the ATM module software release 51.1(5).

Usage Guidelines and Restrictions

This section describes the usage guidelines, warnings, and cautions for the Catalyst 5000 series ATM module software release 51.1(5). It also describes ATM module software problems that are fixed by specific Catalyst 5000 supervisor engine software releases.

All three versions are identical.
Note ATM module software release 11.3(6)WA4(9d) is the release following ATM module software release  11.3(6)WA4(9a); there were no interim releases.

Differences Between Software Releases 51.1(4) and 51.1(5)

This section describes software release 51.1(4) problem that was resolved in Catalyst 5000 series ATM module software release 51.1(5).

If you create and bind a PVC from the command line, the PVC MIB entry for the PVC does not show the correct VLAN value. This problem is resolved in ATM module software release 51.1(5). (CSCdm16575)

Software Modifications and Caveats

This section describes software modifications, unexpected behavior, and other miscellaneous caveats in ATM PVC software release 51.1(5).

This is because when the shutdown/no shutdown commands are performed on the subinterface the PVCs are deleted and recreated. As a result the PVCs lose their bindings to VLANs. The only workaround is to enter the atm pvc vlan command to manually create the PVC-to-VLAN bindings.
We recommend that you configure PVCs on the major interfaces. If you configure PVCs on subinterfaces, we recommend that you do not perform shutdown and no shutdown commands on the subinterfaces. (CSCdk76407)

Note ATM module software release 11.3(6)WA4(9a) is the release following ATM module software release  11.3(6)WA4(9d); there were no interim releases.

Differences Between Software Releases 51.1(3) and 51.1(4)

This section describes software release 51.1(3) problems that were resolved in Catalyst 5000 series ATM module software release 51.1(4).

Commands

This section contains descriptions and examples of the following new or modified commands available in ATM module software release 51.1(1), including the following:

atm pvc

Use the atm pvc command to create a PVC on the Catalyst 5000 series switch interface. Enter the no form of this command to delete the specified PVC.

atm pvc vcd vpi vci [aal-encap] aal5snap peak [oam seconds]
no atm pvc vcd vpi vci [aal-encap] aal5snap peak [oam seconds]
Syntax Description

vcd

Virtual circuit descriptor. A unique number for each Catalyst 5000 series switch that identifies which virtual path identifier/virtual channel identifier (VPI/VCI) to use for a particular packet. The Catalyst 5000 series switch requires this feature to manage packet transmission. The vcd is not associated with the VPI/VCI used for the ATM network cells.

vpi

ATM network VPI of this PVC, in the 0 through 255 range. The VPI is an 8-bit field in the header of the ATM cell. The VPI value is unique only on a single interface, not throughout the ATM network.

vci

ATM network VCI of this PVC, in the 0 through 4096 range. The VCI is a 16-bit field in the header of the ATM cell. The VCI value is unique only on a single interface, not throughout the ATM network.

aal-encap

(Optional) Keyword used for ATM adaptation layer (AAL) encapsulation.

aal5snap

Keyword used for ATM adaptation layer 5/Subnetwork Access Protocol (AAL5SNAP) packet encapsulation type.

peak

Maximum rate in Kbps at which this virtual circuit can transmit. The peak argument must not exceed the maximum PCR for the ATM module used. If a value higher than the maximum PCR is entered, an error message is displayed.

oam seconds

(Optional) Keyword that specifies how often to generate an Operation, Administration, and Maintenance (OAM) F5 loopback cell from this virtual circuit.

Default

If you omit the peak argument, the PVC defaults to the highest bandwidth rate queue available (155,000 Kbps for the OC-3 module; 45,000 Kbps for the DS3 module). By default, the VC is configured to run as fast as possible. If you omit the oam keyword, OAM cells are not generated. If you use the oam keyword, but omit the seconds value, the seconds value defaults to ten seconds.

Command Type

IOS ATM command.

Command Mode

Interface configuration.

Example

This example shows how to configure PVC 10 with VPI 0 and VCI 32. The PVC uses aal5snap mode with a PCR of 45000:

ATM(config-if)# atm pvc 10 0 32 aal5snap 45000
Usage Guidelines

The ATM PVC traffic-shaping software creates rate queues dynamically when an atm pvc command specifies a peak rate that does not match any user-configured rate queue. The atm pvc command creates a PVC and attaches it to the specified VPI and VCI. The vpi and vci values cannot both be specified as 0. For example, if vpi is 0, then vci cannot be 0, and conversely, if vci is 0, then vpi cannot be 0.

Note The peak argument cannot exceed 155,000 Kbps for the OC-3 module or 45,000 Kbps for the DS3 module.

The oam keyword causes the Catalyst 5000 series switch to generate and echo OAM F5 loopback cells, which verify connectivity. Once the OAM cell generation is enabled, a cell is transmitted periodically. The remote end must respond by echoing back the cells.

atm clock internal

Use the atm clock internal command to cause the ATM module on the Catalyst 5000 series switch to generate the transmit clock from its internal source. Enter the no form of this command to set the clock generation mode to receive timing from the received clock.

atm clock internal
no atm clock internal
Syntax Description

This command has no arguments or keywords.

Default

The ATM module generates the transmit clock signal from its internal source.

Command Type

IOS ATM command.

Command Mode

Interface configuration.

Examples

The following example causes the ATM module to generate the transmit clock from its internal source:

ATM(config-if)# atm clock internal

The following example causes the ATM module to generate the transmit clock from the received clock:

ATM(config-if)# no atm clock internal

atm framing

Use the atm framing command to change the default DS3 line framing from C-bit with ATM direct mapping (ADM) to one of the following:

This command is not available to the OC-3 ATM module. Enter the no form of this command to use the default value.

atm framing [m23adm | cbitplcp | m23plcp]
no atm framing [m23adm | cbitplcp | m23plcp]
Syntax Description

m23adm

(Optional) Keyword that specifies M-23 ADM.

cbitplcp

(Optional) Keyword that specifies C-bit with physical layer convergence procedure (PLCP) framing.

m23plcp

(Optional) Keyword that specifies M-23 with PLCP framing.

Default

The default value is C-bit with ADM.

Command Type

IOS ATM command.

Command Mode

Interface configuration.

Usage Guidelines

The atm framing command applies to DS3 interfaces only.

This command allows you to set DS3 framing mode to either M23 ADM, M23 PLCP, C-Bit PLCP, or C-Bit ADM (default value).

Example

The following example selects m23adm frame as the frame type:

ATM(config-if)# atm framing m23adm

atm lbo

Use the atm lbo command to set the line buildout corresponding to the cable length. This command is specific to DS3 and is not available in the OC-3 ATM module.

atm lbo {short | long}
Syntax Description

short

Keyword that sets the line buildout (cable length) up to 255 feet (77.4 meters).

long

Keyword that sets the line buildout (cable length) over 255 feet (77.4 meters).

Default

The default is short.

Command Type

IOS ATM command.

Command Mode

Interface configuration.

Usage Guideline

The atm lbo command applies to DS3 interfaces only.

Example

This example sets the line buildout (cable length) to over 255 feet (77.4 meters):

ATM(config-if)# atm lbo long

atm ds3-scramble

Use the atm ds3-scramble command to enable scrambling on the current port. Enter the no form of this command to disable scrambling. This command is not available to the OC-3 ATM module.

atm ds3-scramble
no atm ds3-scramble
Syntax Description

This command has no arguments or keywords.

Default

The default is scrambling not enabled.

Command Type

Switch command.

Command Mode

Privileged.

Usage Guideline

This command applies to DS3 interfaces only.

Example

This example shows how to enable scrambling:

ATM(config)# interface atm0
ATM(config-if)# atm ds3-scramble

clear counters

Use the clear counters command to clear Media Access Control (MAC) and port counters.

clear counters
Syntax Description

This command has no keywords or arguments.

Default

This command has no default setting.

Command Type

Switch command.

Command Mode

Privileged.

Example

This example shows how to reset MAC and port counters to zero: 

Console> (enable) clear counters
MAC and Port counters cleared.
Console> (enable)
Related Commands

show ltl
show port
