ATM configuration commands

atm-link check

Syntax

atm-link check

undo atm-link check

View

ATM P2P subinterface view

Default level

2: System level

Parameters

None

Description

Use the atm-link check command to make the protocol state of the current ATM P2P subinterface

adaptive to the protocol state of the PVC configured on the subinterface in addition to the state of the

physical interface. Thus, the protocol state of the subinterface is up only when both the physical interface

and the PVC configured on the subinterface are up. Otherwise, the protocol state of the subinterface is

down.

Use the undo atm-link check command to restore the default.

By default, the protocol of the ATM P2P subinterface goes up or comes down depending on the state of

the physical interface.

This command applies only to ATM P2P subinterfaces.

Examples

# Enable the protocol state of ATM P2P subinterface ATM 3/1/1.1 to change depending on the protocol

state of the physical interface and the protocol state of the PVCs configured on the subinterface.

<Sysname> system-view

[Sysname] interface Atm 3/1/1.1 p2p

[Sysname-Atm3/1/1.1] atm-link check

clock

Syntax

clock { master | slave }

undo clock

View

ATM interface view

Default level

2: System level

Parameters

master: Specifies the internal transmission clock (the master clock mode).

slave: Specifies the line clock (the slave clock mode).

Description

Use the clock command to specify the clock signal to be adopted by the current ATM interface.

Use the undo clock command to restore the default.

By default, an ATM interface uses line clock signal (slave).

When two routers are connected back-to-back through ATM interfaces, you must configure the clock

mode to master on one side and to slave on the other side.

NOTE:

• To have an ATM interface work in master clock mode, make sure that the clock modes of all the ATM

interfaces sharing the same slot are set to master.

• The effect of this command applies to both ATM main interface and subinterface. However, the

command is available only in ATM main interface view.

Related commands: display atm interface.

Examples

# Specify interface ATM 3/1/1 to operate in master clock mode.

<Sysname> system-view

[Sysname] interface Atm 3/1/1

[Sysname-Atm3/1/1] clock master

display atm interface

Syntax

display atm interface [ atm { interface-number | interface-number.subnumber } ] [ | { begin | exclude |

include } regular-expression ]

View

Any view

Default level

1: Monitor level

Parameters

interface-number: Number of an ATM main interface.

interface-number.subnumber: Number of an ATM subinterface, in the range of 0 to 1023.

interface-number is the number of the ATM main interface.

|: Filters command output by specifying a regular expression. For more information about regular

expressions, see Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow.

include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Description

Use the display atm interface command to display the detailed information of the specified ATM main

interface or subinterface or all ATM interfaces if no ATM interface is specified.

Examples

# Display the information of interface ATM 3/1/1.

<Sysname> display atm interface Atm 3/1/1

eoapad enable

Syntax

View

Default level

2: System level

Parameters

None

Description

Use the eoapad enable command to enable Ethernet packet padding on an ATM interface.

Use the undo eoapad enable command to disable the function.

By default, Ethernet packet padding is disabled.

When you enable this function on an ATM interface, the interface fills in a sent EoA packet to 60 bytes

if the packet (including the frame header) is smaller than 60 bytes.

Examples

# Enable Ethernet packet padding on interface ATM 3/1/1.

<Sysname> system-view

[Sysname] interface Atm 3/1/1

[Sysname-Atm3/1/1] eoapad enable

NOTE:

This command is also enabled on the ATM subinterfaces when it is enabled on the ATM main interface.

Syntax

flag c2 flag-value

undo flag c2

flag { j0 | j1 } { sdh | sonet } flag-value

undo flag { j0 | j1 } { sdh | sonet }

View

ATM main interface view

Default level

2: System level

Parameters

c2 flag-value: Path signal flag byte, a higher-order path overhead byte that indicates the multiplex

structure of virtual container (VC) frames and property of payload. It is a hexadecimal number in the

range of 0 to FF.

j0 flag-value: Regeneration section trace message, a section overhead byte that tests continuity of the

connection between two interfaces at the section level. If the sdh keyword is configured, the flag-value

argument is a string of 1 to 15 hexadecimal digits. If the sonet keyword is configured, the argument is a

hexadecimal number in the range of 0 to FF.

j1 flag-value: Path trace message, a higher-order path overhead byte that tests continuity of the

connection between two interfaces at the path level. If the sdh keyword is configured, the flag-value

argument is a string of 1 to 15 hexadecimal digits. If the sonet keyword is configured, the argument is a

string of 1 to 62 characters.

sdh: Sets framing format to Synchronous Digital Hierarchy (SDH).

sonet: Sets framing format to Synchronous Optical Network (SONET).

Description

Use the flag command to set the SONET/SDH overhead bytes.

Use the undo flag command to restore the default.

By default, the default SDH overhead bytes are used.

The default overhead bytes are as follows.

• c2: 0x13

• j0 (SDH): Null

• j1 (SDH): Null

Inconsistency between the c2 and j1 settings of the sending end and those of the receiving end causes

alarms.

The j0 byte can be any character in the network of the same carrier. If networks of two carriers are

involved, the sending and receiving routers at network borders must use the same j0 byte. With the j0

byte, operators can detect and troubleshoot faults in advance or use less time to recover the networks.

The inconsistent j0 byte settings at the sending and receiving ends cause alarms in SDH frames but do

not in SONET frames.

Examples

# Set the SDH overhead byte J0 of ATM interface ATM 3/1/1.

<Sysname> system-view

[Sysname] interface Atm 3/1/1

[Sysname-Atm3/1/1] flag j0 sdh ff

Parameters

sdh: Sets the framing format to SDH STM-1/STM-4.

sonet: Sets the framing format to SONET OC-3/OC-12.

Description

Use the frame-format command to set the framing format for an ATM interface.

Use the undo frame-format command to restore the default.

By default, the framing format of an ATM interface is SDH STM-1/STM-4.

Examples

# Set the framing format of ATM 3/1/1 to SONET OC-3/OC-12.
