atmPort
atmPort - configure ATM port parameters.
SYNOPSIS
atmPort sub-command options
DESCRIPTION
The atmPort command is used to configure the ATM port common options.
STANDARD OPTIONS
enableCoset
true | false
If true, enables the Coset algorithm to be used with the Header Error Control (HEC) byte. The code used for the HEC is a cyclic code with generating polynomial x8 + x2 + x + 1. If Coset is turned on, the result of the polynomial is XOR'd with 0x55 (Coset Leader). (default = true)
enablePatternMatching
true | false
If true, then the use of capture and filter based on ATM patterns is enabled in atmFilter and the maximum number of VCCs is reduced to 12, 288. (default = true)
fillerCell
SONET frame transmission is continuous even when data or control messages are not being transmitted. This option allows the cell type that is transmitted during these intervals.
Option |
Value |
Usage |
---|---|---|
atmIdleCell |
0 |
(default) Idle cells are transmitted with VPI/VCI = 0/0 and CLP = 1. |
atmUnassignedCell |
1 |
Unassigned cells are transmitted with VPI/VCI = 0/0 and CLP = 0. |
interfaceType
The type of interface to emulate.
Option |
Value |
Usage |
---|---|---|
atmInterfaceUni |
0 |
(default) User to network interface. |
atmInterfaceNni |
1 |
Network to network interface. |
packetDecodeMode
This setting controls the interpretation of received packets when they are decoded.
Option |
Value |
Usage |
---|---|---|
atmDecodeFrame |
0 |
(default) Decode the packet as a frame. |
atmDecodeCell |
1 |
Decode the packet as an ATM cell. |
reassemblyTimeout
Sets the value for the Reassembly Timeout, which is the period of time (expressed in seconds) that the receive side waits for another cell on that channel - for reassembly of cells into a CPCS PDU (packet). If no cell is received within that period, the timer expires. (default = 10)
sourceLocationId
The source location ID. This value is copied to the defectLocation option of the atmOamAis and atmOamRdi commands when atmPort set is performed. (default = "00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00")
transmitStatMode
This setting controls statistics are collected for the ATM port.
Option |
Value |
Usage |
---|---|---|
atmPerVPIVCIStats |
0 |
(default) Collect statistics for the whole port on a VCI/VPI basis. |
atmDecodeCell |
1 |
Collect statistics for the port on a stream basis. |
COMMANDS
The atmPort command is invoked with the following sub-commands. If no sub-command is specified, returns a list of all sub-commands available.
atmPort cget option
Returns the current value of the configuration option given by option. Option may have any of the values accepted by the atmPort command.
atmPort config option value
Modify the configuration options of the atmPort. If no option is specified, returns a list describing all of the available options (see STANDARD OPTIONS) for atmPort.
atmPort get chasID cardID portID
Gets the current configuration of the atmPort for the port. Call this command before calling atmPort cget option value to get the value of the configuration option. Specific errors are:
- No connection to a chassis
- Invalid port number
- ATM is not a supported feature on this port
atmPort set chasID cardID portID
Sets the configuration of the atmPort in IxHAL for port with id portID on card cardID, chassis chasID by reading the configuration option values set by the atmPort config option value command. Specific errors are:
- No connection to a chassis
- Invalid port number
- The port is being used by another user
- Configured parameters are not valid for this setting
- ATM is not a supported feature on this port
atmPort set Default
Sets to IxTclHal default values for all configuration options.
