Feature Mismatching to Verify LMI/ILMI Support
Traffic Shaping on the UXM Card in Release 9.2
Statistics Supported for BPX ATM Ports (ASI or BXM Front Card)
ATM Connections
This chapter describes the ATM commands that let you activate and configure ATM connections as well as statistical reporting for these connections at an ATM UNI in a BPX or IGX node. You can add ATM connections to an ASI or BXM in a BPX node, or to an ALM/A or UXM in an IGX node. Table 9-1 lists the ATM UNI card combinations for BPX and IGX nodes. For details on ATM commands and other support on an MGX 8220 shelf, refer to the MGX 8220 documentation. For details on ATM commands on an MGX 8550 shelf, refer to the MGX 8550 documentation.
Setting Up an ATM Connection
To set up an ATM connection, perform the following steps:
Step 1
Activate a line with the upln command. Activating a line makes it available so you can configure it. Also, it starts statistics collection. Subsequently, you can begin to add connections with addcon. You can verify that the line has been activated by using the dsplns command. (See the chapter titled " Setting Up Lines" for descriptions of upln and dsplns.)

Managing Bandwidth
There are several commands that assist you in managing bandwidth to achieve satisfactory traffic patterns.
Other Commands
The following commands are useful in establishing connections.
•
Deletes a connection from an ATM line.
•
Displays the connections on a specified ATM line.
•
Displays the line utilization for an ATM line.
Summary of Commands
Table 9-2 shows the name of each ATM connection command and the page the command description starts on.
addcon
Establishes an ATM connection between the current node and one or more nodes in the network. You can add ATM connections at a UNI port on either an ASI or a BXM in a BPX node, or an ALM/A or a UXM in an IGX node. When used with the syntax in this chapter, addcon adds either a standard ATM connection or an ATM-Frame Relay interworking connection. You can also use addcon to add a virtual path connection (or VP tunnelling DAX connection) between a line port on an IGX-UXM as the VP side, and the line port at the ATM cloud entry point as the VCC side. For a description of the addcon command as it applies to Frame Relay connections, voice connections, or serial data connections, refer to the chapter in this manual that describes the applicable traffic type. For descriptions of the ATM commands that operate on an MGX 8220 shelf, see the MGX 8220 documentation. For descriptions of the ATM commands that operate on an MGX 8850 shelf, see the MGX 8850 documentation.
Note that in this release, on BXM and UXM cards, you can configure port and trunk (routing and feeder trunk) interfaces on the same card slot. For example, you can have port 1 on a BXM slot upped as a trunk interface while having port 2 on the same card slot upped as a line interface. For more information on the Port and Trunks feature, refer to the "Setting Up Trunks" chapter.
In Release 9.2.10, you can add VP tunnelling DAX connections. This type of connection has a VP connection as one end of the connection, and the other end as a VC connection. This VP tunnelling DAX connection can be between different port interfaces on the same UXM card, or on different UXM cards. See Example 2.
In Release 9.2.20, you can add both rt-VBR and nrt-VBR connections. The parameter prompts are the same for both rt-VBR and nrt-VBR, except for Trunk Cell Routing Restrict, which displays for all ATM connections except real-time VBR connections. (This is because rt-VBR connections should only be routed over ATM trunks such as BXM, UXM, and ASI trunks; rt-VBR connections should not be routed over FastPacket trunks such as BTM or ALM/B trunks.)
Note
Note that for segment connections, all 2- and 3-segment connections must be the same, that is, all rt-VBR or all nrt-VBR. The CLI will not block you from adding any combination of rt-VBR or nrt-VBR segment connections.
The CLI will block you from adding rt-VBR connections in a network of nodes running releases previous to Release 9.2. All nodes in the network must be first upgraded to Release 9.2.10. In a mixed network of Release 9.1 and 9.2.20, or Release 9.2.10 and 9.2.20, the rt-VBR class of service is not supported—in this scenario, all VBR connections will function as nrt-VBR connections. To support rt-VBR, all nodes in the network must be running switch software 9.2.20. See the Cisco WAN Switching 9.2 Release Notes for more information.
In Release 9.2.0, the switch software supports a minimum Peak Cell Rate (PCR) of 6 cps without policing enabled on both the BXM and UXM. In Release 9.3.0, the switch software supports a minimum PCR of 6 cps with policing enabled (with certain card limitations). Use the dspcd command to determine if this feature is supported on a given slot. Use the addcon command to set the minimum PCR values. If these values are less than the minimum values supported on a given card, the command line interface will not allow you to set them until you have disabled policing. (A prompt will let you know about this limitation, and allow you to disable policing.) Note the following when adding a card:
1.
2.
For ABRSTD, a policing prompt is now added for VSVD=OFF connections.
Please refer to Table 9-5 for a list of cards that are supported by this feature and their performance specifications.
The addcon command for ATM adds any one of the following types of ATM connections:
•
•
•
•
•
•
•
•
•
•
•
Detailed connection sequences can be found in the <CellCommandItalic>Cisco BPX Series Installation and Configuration. This description has the following information:

•
•
•
For detailed descriptions of the connection types, traffic classes, policing, and ATM-related topics, refer to the Cisco BPX 8600 Series Installation and Configuration guide or the ATM Forum specifications.
The node on which addcon executes is the "owner" of the connection. Connection ownership is important because automatic rerouting and preferred routing information is entered on the node that owns the connection. See the cnfpref and cnfcos descriptions for details on automatic rerouting.
The parameter prompts depend on the connection type. The figures on this and the following pages are flow diagrams showing the sequence of possible parameter prompts according to the connection type. The flow diagrams begin at the point after you have entered the remote node name and VPI and VCI (which are common parameters). The subsequent tables define the parameters and list the defaults and ranges for each parameter.
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.
Before a connection is added, the proposed connection appears on the screen prompting you to confirm. After addcon executes, the system software automatically routes the connection.
Instead of entering a class of service, the user can instead enter a class number to select a pre-configured template, for example, class 4 for NTR-VBR, and class 3 for RT-VBR. The class of service templates can be modified as required using the cnfcls/cnfatmcls command and displayed using the dspcls/dspatmcls command.
Note
Note
Network and Service Interworking
Frame Relay to ATM Interworking enables Frame Relay traffic to be connected across high-speed ATM trunks using ATM standard Network and Service Interworking.
Two types of Frame Relay to ATM interworking are supported, Network Interworking and Service Interworking. The Network Interworking function is performed by the BTM card on the IGX switch. The FRSM card on the MGX 8220 supports both Network and Service Interworking.
Figure 9-1 Prompt Sequence for a CBR Connection
Table 9-3 addcon—Parameters
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 range for a UNI connection is 1-255. The VPI range for an NNI connection is 1-4095.
When adding an MGX 8850 interface shelf with a UNI interface to a BPX routing node, the VPI range is 1-255. The VCI range is 1-65535.
When adding an MGX 8850 interface shelf with an NNI interface to a BPX routing node, the VPI range is 1-255. The VCI range is 1-65535.
When adding an SES (Service Expansion Shelf) to an IGX 8400 routing node, for VCC addressing, the VPI range is 1-255. The VCI range is 1-65535.
For VPC addressing, when adding an SES interface shelf to an IGX 8400 routing hub with a UNI interface, the VPI range is 1-255. The VCI range is 1-65535.
For VPC addressing, when adding an SES shelf to an IGX 8400 routing with an NNI interface, the VPI range is 1-4095. The VCI range is 1-65535.
Note
When adding a VP tunnelling DAX connection to an IGX-UXM card, either end of the connection can be the VPI or VCI side. This connection type can be any of the ATM connection types supported by UXM virtual trunks, for example, ABR, CBR, UBR, and VBR.
The VCI range is 1-65535. The vci can be an asterisk (*) to indicate the connection is a virtual path connection (so the vci has no meaning 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 1-255. The vpi range for an NNI connection is 1-4095.
The range for a vci is 1-65535. 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/
traffic typeSpecifies one of the following traffic types—VBR (rt-VBR or nrt-VBR), UBR, CBR, ATFST, ATFR, ABRSTD, ABRFST, ATFT, ATFX, ATFTFST, or ATFXFST; or connection classes—for example, for rt-VBR, connection class 3 for a new node running Release 9.2.20.
The subsequent displayed parameters depend on the connection type you choose. To see the parameters associated with each connection type, refer to the appropriate flow diagrams in the refer to the <CellCommandItalic>Cisco BPX Series Installation and Configuration.
The option for choosing a class number is also available. The class is a template for a connection type. The class 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.
For a new node running 9.2.20 or later, the rt-VBR connection class number is 3. An upgraded node will retain existing connection classes. Therefore, it won't have the rt-VBR connection class 3. However, you can configure the connection classes to whatever service and parameters you want by using the cnfcls/cnfatmcls command.
Note
PCR
Peak Cell Rate: the cell rate that the source cannot exceed.
%Util
Specifies the percentage of bandwidth utilization.
MCR
Minimum Cell Rate: the committed, minimum cell rate for a connection in a network.
CDVT
Cell Delay Variation Tolerance: controls time scale over which the PCR is policed.
FBTC (AAL5 Frame-based Traffic Control)
To enable the possibility of discarding the whole frame, not just one non-compliant cell. This is used to set the Early Packet Discard bit at every node along a connection.
With the ASI, FBTC means packet discard on both policing and queueing. With the BXM, FBTC means packet discard on queueing only.
VSVD
Virtual Source Virtual Destination.
Flow Control External Segments
Enables Cisco WAN switches to perform flow control on external segments (on the CPE, for example) in addition to the Cisco WAN Switching segments.
SCR
Sustainable Cell Rate: the long-term limit on the rate that a connection can sustain.
MBS
Maximum Burst Size: the maximum number of cells that can burst at the PCR and still be compliant. MBS is used to determine the Burst Tolerance (BT), which controls the time period over which the SCR is policed.
Policing
(see Table 9-5)
With the ASI, FBTC means packet discard on both policing and queueing. With the BXM, FBTC means packet discard on queueing only.
VC QDepth
The depth of the queue VC QDepth.
CLP Hi
Cell Loss Priority Hi threshold (% of VC QDepth). When the high threshold is exceeded, the node discards cells with CLP=1 until the number of cells in the queue drops below the level specified by CLP Lo/EPD.
CLP Lo/EPD
Cell Loss Priority Low threshold (% of VC QDepth)/Early Packet Discard. When the number of cells in the queue drops below the level specified by CLP Lo/EPD, the node stops discarding cells with CLP=1.
If the card is a BXM and AAL5 FBTC=yes, the percent of VC QMax equals the value of EPD. Frame-based Traffic Control (FBTC) is FGCRA for AAL5.
The BXM does not support Frame-based Policing.
For an ASI card, the percent of VC QMax is CLP Lo regardless of the FBTC setting.
EFCI
Explicit Forward Congestion Indication threshold (% of VC QDepth).
ICR
Initial Cell Rate: the rate at which a source initially transmits after an idle period.
IBR
Initial Burst Size: the maximum burst size a source can initially transmit after an idle period. IBR applies to only BXM cards.
ADTF (ATM Forum TM 4.0 term)
The Allowed-Cell-Rate Decrease Factor.
Time permitted between sending RM-cells before the rate is decreased to ICR. (In previous software releases, ADTF was ICR TO—Initial Cell Rate Time Out.)
Trm (ATM Forum TM 4.0 term)
An upper bound on the time between forward RM-cells for an active source: an RM cell must be sent at least every Trm milliseconds. (In previous software releases, Trm was Min. Adjust.)
RIF (ATM Forum TM 4.0 term)
Rate Increase Factor: controls the amount by which the cell transmission rate may increase upon receipt of an RM cell. (In previous software releases, RIF was Rate Up.)
RDF (ATM Forum TM 4.0 term)
Rate Decrease Factor: controls the amount decrease in cell transmission rate when an RM cell arrives. (In previous software releases, RDF was Rate Down.)
Nrm (ATM Forum TM 4.0 term)
Nrm.
Maximum number of cells a source may send for each forward RM cell: an RM cell must be sent for every Nrm-1 data cells.
FRTT (ATM Forum TM 4.0 term)
Fixed Round Trip Time: the sum of the fixed and propagation delays from the source to a destination and back.
TBE (ATM Forum TM 4.0 term)
Transient Buffer Exposure
The negotiated number of cells that the network would like to limit the source to sending during start-up periods, before the first RM-cell returns.
PCR
Peak cell rate: the cell rate which the source may never exceed.

Clears the gathered statistics for either a specific channel or all channels. When you enter a specific channel number, the current channel statistics display appears, asking if you want to clear the display. If you enter "*" (all channels) for the channel specification, the display prompts you to confirm whether you want to clear all channel statistics. This is sometimes referred to as a summary statistics command.
The Multilevel Channel Statistics lets you configure and display additional levels of statistics beyond level 1 statistics (for example, levels 2 and 3), as supported by the multilevel channels statistics feature. You use the cnfcdparm command to configure the channels statistics level on the BXM or UXM cards. For example, if you configure slot 5 to support level 3 channel statistics, all connections on that particular card are set to provide level 3 statistics. Switch software collects, displays, and propagates to Cisco WAN Manager the various statistics types. The channel statistic type vary in number and type based on the level of support provided by the BXM and UXM cards. You use the dspchstats and clrchstats to display and clear the statistics.

cnfcon
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:
•
Min cannot exceed peak.
•
Min exceeds this port's speed.
•
Sum of mins exceeds port's speed.
•
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.

cnfport
Configures the parameters of an ATM port on an ASI or BXM card on the BPX or a UXM card on the IGX. Press Return to keep the current value of a parameter. See the parameter table for important information.
Previous to Release 9.2, on the BXM card, only ABR VSVD connections are subject to VC scheduling policies on the egress and that is only when the FCES (external segment) option is enabled. With the introduction of traffic shaping, you can choose whether to perform VC scheduling on CBR, VBR, and UBR traffic streams.
In this release, the Ports and Trunks feature lets you configure multiple trunk lines and circuit lines on a single BXM or UXM card simultaneously. In previous releases, when you upped a single port as a trunk (by using the uptrk command), all the remaining ports on that card were treated as a trunk. Similarly, when you up a single port as a circuit line (by using the upln command), all the remaining ports on the card are treated as circuit line ports. This feature allows BXM and UXM cards to be trunk line cards as well as circuit line cards at the same time. This allows trunks as well as circuit lines to coexist on these interface cards.
Feature Mismatching to Verify LMI/ILMI Support
The cnfport commands, in addition to other configuration commands, perform mismatch verification on the BXM and UXM cards. For example, the cnfport command will verify whether the cards both have LMI/ILMI configured.
The command cnfport will prevent disabling ILMI protocol on a port interface if a VSI ILMI session is active on a VSI partition of the port interface. Configure ILMI protocol running on a port interface to run on the BCC instead of the BXM.
Refer to "Feature Mismatching" in the BPX 8600 Series Installation and Configuration. The Feature Mismatching capability will not mismatch cards unless the actual feature has been enabled on the card. This allows for a graceful card migration from an older release.
Traffic Shaping on the UXM Card in Release 9.2
Traffic shaping lets you choose whether to have VC scheduling performed to your CBR, VBR, and UBR traffic streams. You can configure the traffic shaping (which involves weighted fair queuing) option on each BXM interface. A cnfport parameter will prompt you to enable/disable traffic shaping. (The default is for traffic shaping to be disabled.)
Traffic shaping is performed on a per-port basis. When traffic shaping is enabled, all traffic exiting the port is subject to the VC scheduling based on the appropriate service parameters you provision. When a particular port is configured to perform traffic shaping, all ATM cells, regardless of class of service, pass through the VC queues before leaving the card. Where a port is not configured for traffic shaping, the CBR, VBR, and UBR PVCs circumvent the VC queues and are scheduled by the QBins.
No connections should exist on the port before changing the port traffic shaping parameter. If there are existing connections when the port traffic shaping parameter is toggled, then these connections will not be updated unless the card is reset, connections are rerouted, a switchcc occurs, or you modify the connection parameters. Also, traffic shaping is not enabled on a VSVC endpoint if an external segment has been enabled.
Redundant cards must both support traffic shaping, or neither support traffic shaping. In the non-redundant case, traffic shaping is configurable regardless of whether the BXM card in the target slot supports traffic shaping. If the card does not support traffic shaping, then a BXM card that does support traffic shaping can be inserted later and the traffic shaping configuration will take effect. System software will not perform mismatch checking on the traffic shaping capabilities of the BXM.
The traffic shaping rate parameters are in Table 9-15. The MCR is the minimum cell rate for the connection. This is the lowest rate that the connection will be scheduled from the VC queue into the QBin. The PCR is the peak cell rate, or the highest rate at which the connection will be scheduled from the VC queue into the QBin.

1 Indicates that the system software issues a warning that traffic shaping is not supported on that specific BXM.
Note that traffic shaping does not generate any alarms. There is no mismatch checking for BXMs that support traffic shaping, so if you insert a BXM card with firmware that does not support it, then the traffic shaping functionality will not exist.
Also, cells can be momentarily received out of order when you reconfigure connections between traffic shaping and non-traffic shaping. This is a limitation of the hardware for which there is no workaround.
Configuring Traffic Shaping
Traffic shaping involves passing ATM traffic through the ATM interface at a VC queue, scheduled rate. Currently, in the BXM-only ABR VSVD connections are subject to VC scheduling policies. With the introduction of traffic shaping, the customer will have the option to perform VC scheduling to his/her CBR, VBR, and UBR traffic streams. Traffic shaping is performed by the BXM hardware.
Traffic shaping will be performed on a per-port basis. When enabled, all traffic exiting the port will be subject to the VC scheduling based on the appropriate service parameters provisioned by the user. Note that all ATM cells, regardless of class of service, pass through the VC queues before leaving the card.
No connections should exist on the port before you change the port traffic shaping parameter. If there are existing connections when you toggle the port traffic shaping parameter, then these connections will not be updated unless you reset the card (by using the resetcd command), connections are rerouted, a switchcc occurs, or you modify the connection parameters. Also, it should be noted that traffic shaping is not enabled on a VSVD endpoint if external segment has been enabled.
Redundancy Architecture
Software requires that redundant cards either both support the feature or neither supports the feature. In the non-redundant case, the feature is configurable regardless of whether the BXM card in the target slot supports traffic shaping. If the card does not support the feature, then a BXM card that does support traffic shaping can be inserted later and the traffic shaping configuration will take effect. Switch software will not perform mismatch checking on the traffic-shaping capabilities of the BXM.
Cisco WAN Manager in Release 9.2 has no changes to support traffic shaping. Switch software functionality is limited to enabling the traffic shaping option (involving weighted fair queuing) on a per-BXM interface case. The cnfport command has a new parameter, which will prompt you to enable or disable traffic shaping. The parameter default is to disable the feature.
Refer to the WAN Switch Software Release 9.2 release notes for additional information on traffic shaping. No connections should be on the port before changing the port traffic shaping parameter. If there are existing connections when the port traffic shaping parameter is toggled, then these connections will not be updated unless the card is reset, connections are rerouted, a switchcc occurs, or you modify the connection parameters*. Also, it should be noted that traffic shaping is not enabled on a VSVD endpoint if an external segment has been enabled. In this case, the scheduling policies are based upon the ATMF 4.0 ABR rules.
The MCR is the minimum cell rate for the connection. This is the lowest rate that the connection will be scheduled from the VC queue into the Qbin. The PCR is the peak cell rate, or the highest rate at which the connection will be scheduled from the VC queue into the Qbin.
Firmware Functionality (BXM)
The BXM firmware supports a new Commbus parameter to enable/disable traffic shaping. When you add a connection, the BXM firmware checks its database to see if traffic shaping is enabled for the port that the connection is to be mapped to. If traffic shaping is enabled, the BXM firmware sets up the ASIC hardware to perform the weighted fair queuing. In the background, the BXM firmware runs a rate-based algorithm.
Existing functionality, such as VC queuing, is used by the traffic shaping feature.
In this release, the BXM firmware supports a new CommBus (CBUS) parameter to enable/disable traffic shaping. When a connection is added, the BXM firmware checks its database to see if traffic shaping is enabled for the port that the connection is to be mapped to. If traffic shaping is enabled, the BXM firmware sets up the ASIC hardware to perform the weighted fair queuing. In the background, the BXM firmware runs a rate-based algorithm similar to what is done today for ERS (explicit rate stamping). The only other interface change includes an egress SCR parameter in the channel (0x52) message.
The algorithm executed by the firmware involves the BXM firmware polling the cell arrival and transmit counters of the Qbins approximately every 15 msec. During this time, the firmware determines the congestion ratio:
–
where rp is the previous value of rc, "out" is the number of cells leaving the Qbin, and "in" is the number of cells arriving into the QBIN. Note that if the ratio of out/in is less than 1, then the Qbin is experiencing congestion. The BXM firmware takes the resulting "rc" and divides this value into the sum of all of the PCRs for the Qbin and uses this result as the congestion factor to be programmed into the hardware (SABRE).
Performance of Traffic Shaping
The weighted-fair queuing (WFQ) algorithm for traffic shaping runs the same algorithm as the explicit rate stamping (ERS). Today, this processing consumes 12 percent. Because the algorithm runs once (even if both ERS and WFQ are enabled), traffic shaping will not increase the worst-case demand for BXM processor time.
Errors and Alarm Handling
No alarms will be generated regarding the Traffic Shaping feature. As previously mentioned, there is no mismatch checking for BXMs that do not support the feature, so if you insert a BXM with firmware that does not support the feature, then the traffic shaping functionality will not be supported on that card.
It should be noted that cells can be momentarily received out of order when connections are reconfigured between traffic shaping and non-traffic shaping. This is a limitation of the hardware for which there is no work-around.

cnfportq
Configures queue parameters for a port on an ASI or BXM card on the BPX or a UXM card on the IGX. Pressing the Return key keeps the current value for the parameter.
In Release 9.2.20, the VBR class of service type can be either rt-VBR or nrt-VBR, depending on the way the corresponding port (service) queues (both ingress and egress) are configured. For the nrt-VBR class of service type in this release, the corresponding service queues are larger than in previous releases to provide more efficient bandwidth sharing with other non-real time service types. The service queues for both rt-VBR and nrt-VBR service types can be configured on a node-by-node basis.
You can use cnfportq to configure Qbin values separately for rt-VBR and nrt-VBR connection types on ports. (To configure the qbin values for rt-VBR and nrt-VBR classes of service on trunks, use cnftrkparm.) The rt-VBR and nrt-VBR connections use different queues on a port: these are the rt-VBR and nrt-VBR queues, respectively. (See Example 3 for a cnfportq screen showing the configuration parameters available for a port queue.)
For information on configuring trunk queues used by rt-VBR and nrt-VBR connections, see the cnftrkparm command.
Configuring Port Queues used by rt-VBR and nrt-VBR Connections
The rt-VBR and nrt-VBR connections use different queues on a port, these are the rt-VBR and nrt-VBR queues, respectively. You can configure these separately, using the cnfportq command.

dspcons
Displays information about the connections on an IGX or BPX node. (For information about dspcons for an MGX 8220 card, refer to the MGX 8220 Command Reference.)
Table 9-28 lists all possible information headings that appear in the display. The actual headings that appear depend on the choice of selected optional parameters—including no parameters. The screen examples reflect various optional parameters.
Note
You can also use dspcons to display those connections that have failed the OAM loopback test.
In Release 9.2.20, dspcons will display the rt-VBR and nrt-VBR service types separately.
As you configure VP tunnelling connections on a node, you can display all the VP tunnelling connections on a particular node by using the dspcons -tun command. VP tunnelling connections are indicated by a connection type of "cbrvp", for example, in the Type column of the dspcons screen. For more information on VP tunnelling on UXM cards, see the IGX Installation and Configuration manual.

dspportstats
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 they were last cleared. 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 tests have occurred since the statistics were last cleared.
