The ATM commands are for activating and configuring ATM connections and statistical reporting for these connections. ATM trunks are physical connections between BPX, IGX, or IPX nodes that support ATM connections. The ATM connections on a BPX require the use of either an ASI or BNI front card and a back card that supports T3, E3, or OC3 (STM1). The following table lists the permissible card combinations for BPX lines.
| Application | Front Card | Back Card |
|---|---|---|
| ATM | BNI-T3 | LM-3T3 (Three ports) |
| ATM | BNI-E3 | LM-3E3 (Three ports) |
| ATM | ASI-T3 | LM-2T3 (Two ports) |
| ATM | ASI-E3 | LM-2E3 (Two ports) |
| ATM | ASI-155 | MMF-2-BC |
| ATM | ASI-155 | SMF-2-BC |
| ATM | ASI-155 | SMF LR-2-BC |
| ATM | BNI-155 | MMF-2-BC |
| ATM | BNI-155 | SMF-2-BC |
| ATM | BNI-155 | SMF LR-2-BC |
To set up an ATM connection, perform the following steps:
Step 1 Activate the ATM port with the upport X.X command, where X.X is the shelf slot and port (1-4) of the ATM card set.
Step 2 Use the cnfport command to establish the characteristics for the ATM port.
Step 3 If a suitable class is already configured, note its number and use this class when adding the ATM connection with the addcon command. (The dspcls command displays the parameters for each connection class. The cnfcls command allows an individual class to be modified.)
Step 4 Use the vt command to log in to the node at the remote end of the proposed ATM connection.
Step 5 At the remote node, use the upport and cnfport as listed in steps 1 and 2 to activate and configure the remote port.
Step 6 Use the addcon command at one end of the connection to activate the ATM connection.
There are a number of commands that assist in managing bandwidth to achieve satisfactory traffic patterns.
| cnfpref | The configure preference command can be used to specify preferred routing for intra-domain connections. This command can be used to assist in balancing the load on the network's trunks. |
| dsprts, prtrts | The display and print routes commands can be used in conjunction with the cnfpref command to display the current connection routing information. |
| upcon, dncon | The up and down connection commands can be used to temporarily down connections, thus releasing bandwidth for other services. Often it is possible to down some voice connections to provide more bandwidth for data, frame relay, or ATM traffic. |
The following commands may be useful for establishing connections.
| · delcon | deletes a connection from an ATM line. |
| · dnln | downs a line. A downed line is deactivated with no drive signals and no statistics. All connections on the line must be deleted (delcon) before a line can be downed. |
| · dspcons | displays the connections on a specified ATM line. |
| · dsplns | displays the line configuration and alarm status for the node. |
| · dsplnutl | displays the line utilization for an ATM line. |
The location of each ATM command description appears in the following table:

Establish an ATM connection for a channel between the current node and one or more nodes in the network. You can specify a port on either an ASI, BNI, BTM, or AIT front card. For a description of the addcon command as it applies to frame relay connections, voice connections, or data connections, refer to the chapter that applies to the specific connection type. When used with the syntax in this chapter, addcon adds either a standard ATM connection, a frame relay-to-ATM interworking connection (ATFR), or a frame relay-to-ATM interworking with ForeSight (ATFST) connection.
The node on which addcon executes is the "owner" of the connection. Connection ownership is important because automatic rerouting and preferred routing information for a connection is entered on the node that owns the connection. See the cnfpref and cnfcos descriptions for information on automatic rerouting.
The displayed parameter prompts depend on the connection type. Before a connection is added, the proposed connection appears on the screen with a prompt for confirmation. After addcon executes, the system software automatically routes the connection. The figures on this and the following pages are flow diagrams showing the sequence of possible parameter prompts according to the connection type and whether Usage Parameter Control (UPC) is enabled. The flow diagrams begin after the remote node name and VPI and VCI have been entered. The subsequent tables define the parameters and list the defaults and ranges for each parameter. Refer to the System Manual and the ATM Forum specifications for more details on ATM parameters and concepts such as the leaky buckets for controlling cell admissions to the network.
A form of notation appears for some parameters that may need explanation. The notation is either (0), (1), or (0+1). This refers to the state of the Cell Loss Priority (CLP) bit. The usage of the CLP bit is in the traffic policing schemes. (0+1) means cells with CLP=0 or 1. (0) means cells with CLP=0. (1) means cells with CLP=1. The CLP bit is used in different contexts. For example, CDVT (0+1) refers to Cell Delay Variation Tolerance (CDVT) for cells with CLP=0 or 1. CDVT (0) means CDVT for cells with CLP=0. PCR(0) means PCR for cells with CLP=0. For a description of CLP and CDVT usage and policing concepts in general, refer to the System Manual and the ATM Forum specifications.
The following table contains descriptions of the ATM parameters that appear on screen. The subsequent table gives the defaults, ranges (or values), and granularity for each parameter. The last section contains screen examples. The preceding flow diagrams help clarify the information in these forthcoming sections.
| Parameter/Prompt | Description |
|---|---|
| local channel | Specifies the local slot, port, virtual path identifier (vpi), and virtual connection identifier (vci) for the connection. The format is slot.port.vpi.vci. The vpi and vci ranges are:
The vpi range for a UNI connection is 0-255. The vpi range for an NNI connection is 0-1023 The range for a vci is 1-4095. The vci can be an asterisk (*) to indicate the connection is a virtual path (the vci does not provide a distinction within the network). |
| remote node name | Specifies the name of the node at the other (or remote) end of the connection. |
| remote channel | Specifies the remote node's slot, port, vpi, and vci for this connection. The format is slot.port.vpi.vci. The vpi and vci ranges are:
The vpi range for a UNI connection is 0-255. The vpi range for an NNI connection is 0-1023 The range for a vci is 1-4095. The vci can be an asterisk (*) to indicate the connection is a virtual path (the vci does not provide a distinction within the network). |
| connection class | Specifies one of the following connection types: VBR, CBR, ABR, ATFR (VBR with ATM-to-frame relay interworking), or ATFST (ABR with interworking and ForeSight). The parameters that follow this selection depend on the chosen connection type. Refer to the flow diagrams on the preceding pages.
The option for choosing a class number is also available. The class is a template for a connection type. This serves as an alternative to specifying each parameter for a connection type. To specify a connection class, enter a digit in the range 1-10. To see the parameter values for a class, use the dspcls commands. To customize any class template, use cnfcls. |
| ABR | T3/E3: Enables/disables ForeSight. Refer to the flow diagrams on the preceding pages for help with the following explanation:
If the connection type selected at the "connection class" prompt was VBR and ABR is enabled at this prompt, the connection type changes to ABR, and prompts for ABR parameters subsequently appear. On the other hand, if the selected connection type is ABR and ABR is disabled at this ABR prompt, the connection type changes to VBR, so only VBR parameters are requested. |
| PCR(0+1) | T3/E3: Specifies the transmit/receive Peak Cell Rate (PCR) for cells leaving the first leaky bucket on the ASI card with CLP(0+1). Applies to only CBR connections.
OC3 (STM1): Specifies the transmit/receive Peak Cell Rate (PCR). The range is 10 cps up to the maximum line rate. (See table of defaults and ranges.) |
| UPC | T3/E3 or OC3 (STM1): Enables/disables Usage Parameter Control (UPC). With UPC, additional user-specified parameters become available for each connection type. Refer to the preceding flow diagrams to see the parameters available for each connection type. The system uses the default if no parameter change occurs. See next table for defaults. |
| FGCRA | T3/E3: Enables either the Frame-Based Generic Cell Rate Algorithm (FGCRA) or the standard GCRA (the default).
FGCRA controls automatic cell discarding (or tagging) of the remainder of a frame when one cell from the frame is non-compliant. FGCRA is a StrataCom enhancement of the ATM-UNI Generic Cell Rate Algorithm (GCRA) for associating a cell with the frame from which it originated. StrataCom supports configuration on a per-connection basis. |
| CDVT(0+1) | T3/E3 or OC3 (STM1): Specifies the transmit/receive Cell Delay Variation Tolerance (CDVT) for the first leaky bucket, which applies to cells with CLP(0+1). CDVT is the maximum time for accumulated violations of cell-arrival time parameters. |
| PCR(0) | T3/E3: Specifies the transmit/receive Peak Cell Rate (PCR) for cells leaving the second leaky bucket [CLP(0)] on the ASI card.
OC3 (STM1): PCR(0) not used by ASI-2 OC3 (STM1). |
| CDVT(0) | T3/E3: Specifies the transmit/receive Cell Delay Variation Tolerance (CDVT) for the second leaky bucket. The second bucket applies to cells with CLP(0). CDVT is the maximum time for accumulated violations of cell-arrival time parameters.
OC3 (STM1): CDVT(0) not used by ASI-2 OC3 (STM1) card. |
| SCR policing | T3/E3: Specifies the traffic policing for a VBR or ABR connection. The possible policing configurations are SCR policing of CLP (0+1) (which is selected as SCR#2), SCR policing of CLP(0) (which is selected as SCR#1), or SCR policing off (SCR#3). The SCR Policing parameter is not used by ASI-2 OC3 (STM1) card. |
| SCR | T3/E3: Sustainable Cell Rate (SCR) specifies a compliant cell rate threshold for transmit/receive. SCR is available with ABR and VBR connections and is less than or equal to the Peak Cell Rate (PCR). The ASI-2 OC3 (STM1) card does not use SCR policing. |
| MBS | T3/E3 or OC3 (STM1): The transmit/receive Maximum Burst Size for SCR policing. |
| CLP tagging | T3/E3 and OC3 (STM1): Enables/disables Cell Loss Priority (CLP) tagging. If CLP tagging is enabled, the CLP bit is set as a result of a UPC violation. |
| MCR | T3/E3: Specifies the transmit/receive Minimum Cell Rate (MCR) for ABR connections. |
| ICR | T3/E3: Specifies the transmit/receive Initial Cell Rate. ICR is the rate that occurs after a period of inactivity on an ABR connection. (This period is the value of ICR TO). The cell rate then goes up or down under the control of the ForeSight Rate Control Algorithm. The range is 0 cps through the line's maximum. The ICR default is a range under the control of the ForeSight Rate Control Algorithm. See also the descriptions of Rate Up and Rate Dn. |
| ICR TO | T3/E3: ICR timeout. Specifies a period of inactivity before a connection's cell rate is reset to the specified ICR. |
| Rate Up | T3/E3: Specifies the increment in cell rate when the rate goes up. This ForeSight Rate Up increment is in cells per second per adjustment. |
| Rate Dn | T3/E3: Specifies large reductions in the transmit/receive cell rate. This ForeSight Rate Down value is a percentage of the current rate. |
| Rate FastDn | T3/E3: Specifies a rate of decrease in the transmit/receive cell rate when ForeSight quickly adjusts the rate down. This value is a percentage of the SCR. |
| Minimum Adjust | T3/E3: Minimum Adjust Period specifies the interval before the ingress sends rate adjustments for ABR connections. This is the time period before either a rate adjustment is made or a message is sent that an adjustment is not necessary. It serves as a stand-in round trip delay until a true RTD is measured. Older software refers to this as Maximum Adjust Rate. |
| VC Qdepth | T3/E3: Specifies the maximum ABR VC queue depth for transmit/receive. |
| EFCI | T3/E3: The transmit/receive percent of ABR VC queue depth that causes EFCI to be set. |
| CLP Hi | T3/E3: Specifies a percent of the transmit/receive ABR VC queue depth. When a transmit/receive threshold is exceeded, the node discards cells with CLP=1 in the connection until the VC queue level falls below the depth specified by CLP lo. |
| CLP Lo | T3/E3: Specifies a percent of the transmit/receive ABR VC queue depth such that, when the VC queue level falls below this level, the node stops discarding CLP=1 cells. |
| IBS | T3/E3: Initial Burst Size (IBS) for transmit/receive. Applies to only ABR connections. |
| RM | T3/E3: Enables Resource Management cells to go to a port on an ASI. RM cells provide backwards congestion notification, which subsequently goes to external equipment. For BNI cards, leave RM disabled. In older software, the name of this parameter is BCM. |
| % Util | T3/E3: Specifies the percent of bandwidth utilization for a connection. The allocation of trunk bandwidth that is based on %util depends on the connection type, as follows:
For CBR, the default is 100%, and the bandwidth allocation is PCR(0+1) * %util. For VBR, the default in the command prompt is the minimum of either 100% or 120(SCR/PCR). The bandwidth allocation is PCR(0+1) * %util. For ABR, the default is 100%. The bandwidth allocation is MCR * %util. |

Sets up a group to which ATM connections between the local node and a remote node are added. The connection group is a routing entity that is initially empty and to which individual connections (virtual circuits) are added using the grpcon command. Connections added to a group must be of the inter-node, non-bundled, ATM type. The connections must have the same routing parameters. These parameters include connection owner, class of service (COS), connection state, route restrictions, and ForeSight enable status.
Connection grouping permits an IPX or IGX node to have up to 1000 connections and a BPX node to have up to 5000 connections. A connection group may have up to 16 connections.

Configures the ATM bandwidth parameters for a specified connection. The initial cell rate (ICR) normally is set to the port speed. It may be lower if other constraints exist on the data generation rate. If ICR is too low, cells are dropped. If it is too high, bandwidth may be wasted unless ForeSight is used. Statistical reports are the best source of information for deciding what to adjust.
If the connection type includes ForeSight (abr enabled), the results of the last test round trip delay command (tstdelay) appear. Note that this is not the current RTD but the result of the last test that ran. Connection priority -- high or low -- is displayed for standard frame relay connections and ForeSight connections. Several checks are done on the parameters that specify bandwidth to assist users in efficient use of network bandwidth. The following messages describe the performance evaluation.
| · Error | Min cannot exceed peak. |
| · Warning | Min exceeds this port's speed. |
| · Warning | Sum of mins exceeds port's speed. |
| · Warning | Peak exceeds this port's speed. |
Warning messages are informational only, so the related operation continues. If an error message appears, the operation does not continue.

| Parameter | Description |
|---|---|
| slot.port | Specifies the ASI card slot and port number. |
| nni/uni | Specifies whether the cell header format is NNI or UNI. |
| axis | Specifies AXIS queue depth for each slot. |
| metro data cell header | Specifies whether the metro data cell header type is used. |
| shift h | n | Specifies whether a one-byte shift on the HCF field of the cell header occurs. The choice of H (shift) or N (no shift) depends on whether the ATM cloud includes non-StrataCom nodes and whether virtual trunking is in operation:
Select H (the default) if the cloud includes non-StrataCom nodes or if only a physical trunk is configured for the ASI port. Select N if virtual trunks are configured and the ATM cloud consists of StrataCom nodes only. |
| protocol | Specifies the use of either an LMI protocol, an protocol, or no specified protocol. |
| %util | Enables/disables percent utilization. This parameter supports ATM VBR/ABR fairness for ASI terminated connections and applies to only VBR and ABR connections. To change the %util status of a port, no connections can be currently terminating on the port. Therefore, if connections terminate on the port, they must be deleted before cnfport execution then re-added after execution of cnfport.
When this feature is disabled, the port queue bandwidth is calculated using the sum of the MCRs or PCRs for the connections terminating on the port. This is identical to the port queue bandwidth calculation prior to the implementation of the %util feature. The port queue bandwidth with %util feature disabled is:
When the %util feature is enabled, the port queue bandwidth is calculated for ABR and VBR connections as follows: for ABR connections, the port queue bandwidth is the sum of a percentage of the MCRs for the connections terminating on the port; for VBR connections, the port queue bandwidth is the sum of a percentage of the PCRs for connections terminating on the port. The feature is not applied to CBR connections. In summary, the port queue bandwidth with feature %util enabled is:
For CBR connections Port Queue BW = sum (PCR) |

Displays a summary of port statistics for the ATM port specified. These include the cell count in the transmit and receive directions, and error counts associated with the port. The display indicates the date and time that the statistics were cleared and the statistics collection time since the last clearance. Cells transmitted indicates the amount of data transmitted out the port to the user device. Cells received indicates the amount of data received from the user device at the port. Corrupted statistics result from channel/port loopbacks or port tests. A yes in this field indicates that such loopback or port test have occurred since the statistics were last cleared.

Adds a connection to a group. Adding a connection to a group has two prerequisites:
No command exists to delete an individual connection from a group. Instead, the connection must be deleted (using delcon) then added again. The grpcon command can be used to add either a single connection or multiple connections. Using the optional channel ... channel parameter format, a range of 1 - 16 connections can be added to the group in one command. All connections in the group must be of the inter-node, non-bundled ATM type. They must also have the same endpoints, routing characteristics, and ForeSight enable status.
The first connection added to a group determines the routing characteristics of the entire group. All subsequent connections must match the first connection's characteristics of ownership, COS, routing state, routing restrictions, and ForeSight. Attempting to add a dissimilar connection results in an error message "mismatched connection/group" characteristic. For example, the ownership of both the connection group and the connection itself must be either local or remote. Non-connection parameters, such as fail state, loop state, and configuration, can be specified for an individual connection in the group after the connection has been added to the group.
