SPVC and SVC Commands
This chapter describes the commands that apply to semi-permanent virtual circuits (SPVCs) and
switched virtual circuits (SVCs). These commands allow you to add, delete, configure, display status,
and specify statistics for these connections. The commands include the following areas:
•
Adding a connection
•
Modifying an existing connection
•
Deleting a connection
•
Display one connection or all connections
•
Downing and upping a connection in the course of maintenance or troubleshooting
Position-Dependent and Keyword-Driven Parameters
A command can include parameters that are keyword-driven or position-dependent.
For position-dependent parameters, you must type parameters in the order they appear in the syntax
description or on-line help. To create a logical port, for example, the position-dependent syntax is:
addport <ifNum> <bay.line> <guaranteedRate> <maxrate> <sctID> <ifType> [vpi]
For a keyword-driven parameter, a keyword must precede the value. The keyword is preceded by a dash
and followed by the parameter (–timeout <secs>, for example). The order you enter keyword-driven
parameters does not matter—although any preceding or succeeding, position-dependent parameters
must appear as they do in the command syntax description.
In the following syntax example, the command is to delete more than one connection at a time. The
mandatory, position-dependent connection identifier consist of a logical port (ifNum) and the VPI and
VCI of the first connection to delete. After the connection identifier, the line shows two optional,
keyword-driven parameters. These keyword-driven parameters let you enter the number of connections
to delete and specify verbose mode:
delcons <ifNum> <vpi> <vci> [-num <num. conns to del>] [-verbose < 1 | 0 >]

Command Entry
Command Entry
When you enter a command with the current version of the product, you must type all intended
arguments before you press the Return key or Enter key.
If you press the Return key or Enter key with incorrect parameters or no parameters (if the command
requires parameters), a message displays the syntax and parameter ranges. The returned message may
also suggest what the problem is. For example, the message may warn of too few parameters. No error
messages or warnings appear until you complete the command.
Identifying the AXSM Models
The model number of an AXSM identifies the line speed, line count, and number of bays (see Table 7-1.)
Note that the number of lines applies to an individual back card, so the total number of lines supported
by the front card equals the highest line number times the number of bays. The OC-48 card
AXSM-1-2488 has the lowest number of lines—one. The highest number of lines exist on the
AXSM-16-155 and AXSM-16-T3E3—16, as the name indicates.
The MGX 8850 node uses the concept of a bay. The bay refers to the upper or lower location of a
single-height card. (The switch has a double-height card cage, so a single-height back card necessarily
occupies either an upper or lower position.)
The T3/E3, OC-3, and OC-12 versions of the AXSM can have two back cards, one in bay 1 (upper
location of the back slot) and the second in bay 2 (lower slot). The MGX-AXSM-1-2488 (OC-48 AXSM)
can have a back card in bay 1 only. For further descriptions and illustrations of the card sets, refer to
Cisco MGX 8850 Hardware Installation, Release 2.

Connection Capacities of the AXSM
The SVC and SPVC connection capacities for the front card, back card, and physical lines appear in
Table 7-2 and Table 7-3. The capacity of a single AXSM card is greater than that of the node itself.
Nevertheless, the tables provide these maximums when you plan the use of commands such as
addrscprtn, addcon, and any other command where you may want to know the capacity of the
configured item to support connections.

Identifying Physical and Logical Elements
The Private Network-to-Network Interface (PNNI) control protocol and the service modules use
different formats to identify the same entity. For example, the format of a logical port that you enter on
an AXSM is different from the format you would enter on the PXM45. This section describes these
formats in the PNNI and AXSM contexts and how they correspond to each other. The parallel actions of
configuring or displaying logical elements on different cards is broadly illustrated in the Cisco
MGX 8850 Routing Switch Software Configuration Guide, Release 2.0.
Apart from the way PNNI and the lower levels of logic identify the same element, the sequence of
commands also needs explanation. When you configure logical ports—for just one example—you must
complete certain tasks on the AXSM CLI before or after related PNNI tasks. For certain commands, this
manual lists prerequisite commands or tasks. For more details on the sequence of tasks, refer to the Cisco
MGX 8850 Routing Switch Software Configuration Guide, Release 2.0, for more details of this sequence.
AXSM Format
On a service module, you identify the follow when you provision the capabilities of the card:
•
Slot
•
Bay
•
Line
•
Logical port
•
Port group
•
Resource partition

SPVC and SVC Commands
Identifying Physical and Logical Elements
Not all of these elements correspond to elements you specify on the PXM45. Subsequent paragraphs
describe only the common elements that are visible on the CLI of the PXM and the service module. The
preceding elements are further defined in the Cisco MGX 8850 Routing Switch Software Configuration
Guide, Release 2.0.
For a UNI or NNI, one logical interface (or logical port) exists per physical line. For virtual network to
network interfaces (VNNIs), you can configure multiple ports on a line. The maximum number of logical
ports on an AXSM is 60 regardless of the AXSM model or the number of lines on the back cards. The
range of logical port numbers is 1–60 for an AXSM regardless of whether the interface type is UNI, NNI,
or VNNI.
PNNI Format
The PNNI controller requires the following format to identify a physical port:
[shelf.]slot[:subslot].port[:subport]
The PNNI physical port identifier (physical port ID) consists of a series of mandatory elements. Note
the period or colon associated with each element inside the square brackets. The elements of the physical
port ID are as follows:
•
The shelf is always 1 for the current product and so is usually omitted.
•
The slot number of the front card.
•
Subslot is the number of the bay where the back card resides. This number is 1 or 2.
•
Port is the physical line.
•
Subport corresponds to the resource partition on the AXSM. For a UNI or NNI, this resource
partition is the same number as the logical port number (ifNum) on the AXSM. For a virtual
network-to-network interface (VNNI), the number does not directly correspond to the
For each physical port number, PNNI also generates a logical port number as an encrypted form of the
physical port number. The logical port number appears as an unformatted numerical string. For example,
a PNNI physical port ID may have the form 1:1.2:2, so the PNNI logical port number would be
16848898. Where needed, the descriptions in the PNNI command chapter define the need for this logical
port number. (This section does not define a PNNI logical port number, nor does it describe the
correspondence between an AXSM port and a PNNI logical port number.) For the correspondence
between a PNNI physical port and the port identifier on an AXSM, see Table 7-4.

As Table 7-4 shows, a port to PNNI is a line on the AXSM, and a subport to PNNI is a logical interface
(or logical port) on an AXSM. An example of a PNNI physical port identifier is 1:2.1:1. This portid
corresponds to an AXSM, with the following particulars:

SPVC and SVC Commands
addcon
addcon
Add Connection
Adds a logical connection as an SPVC on a service module. The switch assigns a 20 octet NSAP address
to the slave endpoint, which is sent back to the master and uniquely identifies the endpoint on the
network. An AXSM front card can support a maximum of 64K SPVCs. This command does not apply
to SVCs.
Before Adding a Connection
Before you can add an SPVC, the following tasks must have been completed:
1.
The switch must have a network controller (see addcontroller description).
2.
A physical line must be active. Use the upln command or the CiscoView application.
3.
At least one logical port must exist on the active physical line. Use the addport command or the
CiscoView application to create the port. If necessary, modify the port through cnfport.)
4.
At least one resource partition must exist on the logical port. Use the addrscprtn (or addpart,)
command or the CiscoView application. The resource partition should be associated with the
controller you add in step 1.
Adding a Connection
Adding a connection requires you first to provision a slave endpoint. Subsequently, you again execute
addcon to provision a master endpoint. The master endpoint of the connection initiates the routing of
the call and can be viewed as the “calling” party. The slave endpoint is the called endpoint. The following
are characteristics of this master-slave arrangement:
•
When you add a slave endpoint, the system returns a slave endpoint identifier. You subsequently
need to provide this slave endpoint identifier when specifying the master endpoint.
•
When you add the master endpoint, you must provide the slave endpoint identifier. (A copy and
paste operation is probably more convenient than writing down the slave endpoint identifier.) After
you finish adding the master endpoint, the switch starts routing the connection.
To modify the bandwidth parameters or configure usage parameter control (UPC), use cnfcon for all
service types. In addition, ABR connections require more configurable parameters for implementing
closed loop control. Use cnfabr to configure the ABR parameters. (Note, however, that ABR VSVD is
not supported in the current release.)
Usage Guidelines
The following sections detail the application of certain addcon parameters.
Traffic Parameters
Traffic parameters such as PCR, SCR, MBS are entered at both the master and slave endpoints for both
the forward and reverse directions. Be sure that the value entered as “local” on one end is equal to the
value entered as “remote” on the other end. For example, the lpcr on the slave endpoint should be same
as the rpcr on the master endpoint and vice versa when you provision the connection at the other end. If
you modify traffic parameters after creating an SPVC, you just modify them at either the master endpoint
or the slave endpoint.

SPVC and SVC Commands
addcon
Traffic parameters such as CDV, CTD are entered at both the master and slave endpoints for both the
forward and reverse directions. However, the values of these parameters entered at the slave end are
ignored during call setup. Therefore, you can specify the lcdv, rcdv, lctd and rctd options at the master
end only.
SCT Default Traffic Parameters
The Service Class Templates (SCTs) provide the default traffic parameters for the logical ports. The
default traffic parameters are set to a fraction of the bandwidth available on the logical port. The SCT
ID (sctID) and interface type (ifType) parameters that are specified using the addport command
determine which default traffic parameters are used.
Note
The default values of the SCTs cannot be changed using the Cisco WAN Manager (CWM).

Default : Taken from the SCT which was chosen for the virtual interface. The service
type is used as an index in choosing a value of PCR. The default value of PCR in the
SCT is defined as a percentage of the interface bandwidth.
SCR
Minimum value of 7 cells/sec.
Maximum is limited to the PCR.
Default: Taken from SCT as a percentage of PCR.
MCR
Same as SCR
Routing Parameters
The routing parameter maxcost (specified using -mc option) need to be entered at the master endpoint
only. The values of the parameters entered at the slave end are ignored and during call set-up.
Frame Discard
For the parameter frame discard (specified using -frame option), you need to enter it at only the master
endpoint. This parameters has no significance at the slave end.
For the MGX 8850 2.0 release, if you try to enable frame discard at the slave end point you will not get
an error message. Nothing will happen, and frame discard will not take effect. In future releases, an error
message will be displayed if you try to enable frame discard at the slave end point.
Local-Only Parameters
The parameters CDVT, stats enable, cc enable (specified using -cdvt, -stat, -cc) are significant only at
the endpoint where you enter them. Therefore, they can be different at each end of the connection.

(mastership=m or 1).
-lpcr
Local Peak Cell Rate (PCR). Specifies the PCR from a local endpoint to a remote
endpoint (3–5651328 cells per second). Peak Cell Rate is the maximum cell rate
for the connection at any time.
-rpcr
Remote Peak Cell Rate (PCR). Specifies the PCR from a remote endpoint to a
local endpoint (3–5651328 cells per second). Peak Cell Rate is the maximum
cell rate for the connection at any time.
-lscr
Local Sustained Cell Rate (SCR). Specifies the SCR from a local endpoint to a
remote endpoint (3–5651328 cells per second). Sustained Cell Rate is the
maximum cell rate that a connection can sustain for long periods.
-rscr

-cdvt
Local Cell Delay Variation Tolerance (CDVT). Specifies the CDVT from a local
endpoint to a remote endpoint (1–5000000 microseconds). Cell Delay Variation
Tolerance controls the time scale over which the PCR is policed.
Note that no remote CDVT is necessary.
-lcdv
Local Cell Delay Variation (CDV). Specifies the CDV from a local endpoint to
a remote endpoint (1–16777215 microseconds). Cell Delay Variation is the peak
to peak cell delay variation expressed in microseconds.
-rcdv
Remote Cell Delay Variation (CDV). Specifies the CDV from a remote endpoint
to a local endpoint (1–16777215 microseconds). Cell Delay Variation is the peak
to peak cell delay variation expressed in microseconds.
-cc
Operations, administration, and maintenance continuity check (OAM CC): enter
1 to enable or 0 to disable. The default is 0.
To provision continuity checking, you must enable this function at both ends of
the connection, otherwise a connection alarm results. Therefore, even as you
create the connection with this parameter, the connection goes into alarm until
both ends of the connection are up.
-stat
Statistics collection: enter 1 to enable or 0 to disable. The default is 0.
The Cisco WAN Manager tool collects statistics for a connection if you enable
it here. Statistics collection is disabled for all connections by default. Statistics
collection has an impact (which may not be significant) on the real-time
response, especially for SVCs (which can be affected even though you do not
add SVCs). Therefore, you should enable statistics collection for only the subset
of connections that really warrants such a feature.

-frame
Frame discard: Enter a 1 to enable or a 0 to disable. The default is disabled (0).
-mc
Maximum cost (maxcost): a value that creates a priority for the connection route.
The switch can select a route only if the cost does not exceed maxcost. The range
for maxcost is 0–2147483647. If you do not specify maxcost, the connection has
the highest routing priority by default. Therefore, the maxcost parameter lets you
lower the routing priority of a connection. Note the following effects of values
in the maxcost rage:
•
To assign the highest priority to an SPVC based on cost (any path is
acceptable), enter 2147483647. You can achieve the same result by not
specifying maxcost at all, in which case the cost appears as a –1 in the
dspcon output. (You cannot enter a –1 for either maxcost in addcon or to
the cnfpnni-intf command, but display commands can show unspecified
values as –1.).
•
Enter a 0 for optimal (or least expensive) path.
•
For any non-zero maxcost, the switch assigns a path if the total cost for all
links does not exceed maxcost.
Although maxcost applies to an individual connection, routing costs
substantially depend on a cost-per-link that you specify at every PNNI logical
port in the network. The applicable PNNI command is cnfpnni-intf. (See the
description of the administrative weight parameter for cnfpnni-intf in the
chapter, “PNNI Commands.”
The cost of a route is as follows:
routing cost=sum of all costs-per-link
where:
•
The cost-per-link has been specified through cnfpnni-intf at the egress of
each logical port under PNNI control throughout the network. The impact
of cost-per-link is cumulative, not just local.
•
Each link has two egress points: one going to the far endpoint, and one in
the return direction. The cost-per-link can differ in each direction, so the
switch adds the cost-per-link in each egress instead multiplying cost by two.
The cost-per-link applies to all connections of a particular service type on a port.
For example, the cost-per-link is the same for all VBR.1 connections that PNNI
controls on a port, and this cost can differ from all UBR.1 connections on the
same port. Alternatively, you can use cnfpnni-intf to make the cost-per-link the
same for all service types.
To illustrate by examining a four-link route:
1.
You specify a maxcost of 100000.
2.
A potential route has four links for a total of eight egress points (four going
to the endpoint and four coming back).
3.
The cost-per-link at 6 ports is 5040 (the default) and 10000 at 2 ports.
The PXM45 would use the route because the resulting cost of 50240 is less than
the maxcost of 100000.

Error Messages
The system can display error messages for the following reasons:
•
Some of the traffic management parameters apply to specific service types (rt-VBR, for example).
If you type a parameter that does not apply to a selected traffic type, the connection is rejected.
•
Insufficient resources are available to accept the provisioning request.
•
The type of card does not support a certain feature.
•
The port cannot support SPVCs.
One of the following error messages appears if one of the preceding causes is true:
•
“Port does not support requested serviceType”

cnfcon
Configure Connection
Modifies the bandwidth, policing, and routing parameters of an existing endpoint. This command applies
to only an SPVC or SPVP. For ABR-specific parameters, use the cnfabr command.
The command parameters consist of:
•
A logical port, VPI, and VCI to identify the connection
•
Bandwidth parameters for the local (master) end then the remote (slave) end
•
Policing parameters for the connection as a whole
After you specify the mandatory connection identifier, all other parameters are optional.
Card(s) on Which the Command Executes
AXSM
Usage Guidelines for cnfcon
The following sections discuss the application of certain cnfcon parameters.
Note
On DAX connections, using cnfcon at the slave end has no effect. For DAX connections, use cnfcon
at the master end only, and the parameters will take effect on the controller as well.
Traffic Parameters
Traffic parameters such as PCR, SCR, MBS are entered at both the master and slave endpoints for both
the forward and reverse directions. Be sure that the value entered as “local” on one end is equal to the
value entered as “remote” on the other end. For example, the lpcr on the slave endpoint should be same
as the rpcr on the master endpoint and vice versa when you provision the connection at the other end. If
you modify traffic parameters after creating an SPVC, you just modify them at either the master endpoint
or the slave endpoint.
Traffic parameters such as CDV, CTD are entered at both the master and slave endpoints for both the
forward and reverse directions. However, the values of these parameters entered at the slave end are
ignored during call setup. Therefore, you can specify the lcdv, rcdv, lctd and rctd options at the master
end only.
Routing Parameters
The routing parameter maxcost (specified using -mc option) need to be entered at the master endpoint
only. The values of this parameters entered at the slave end is ignored and not considered during call
setup.
Frame Discard
For the parameter frame discard (specified using -frame option), you need to enter it at only the master
endpoint. This parameters has no significance at the slave end.
For the MGX 8850 2.0 release, if you try to enable frame discard at the slave end point you will not get
an error message. Nothing will happen, and frame discard will not take effect. In future releases, an error
message will be displayed if you try to enable frame discard at the slave end point.

cells that can burst at the PCR and still be compliant.
- rmbs
Keyword that specifies the Maximum Burst Rate (MBS) from a remote endpoint to a

cells that can burst at the PCR and still be compliant.
- cdvt
Keyword that specifies the Cell Delay Variation Tolerance (CDVT) from a local
endpoint to a remote endpoint (1–5000000 microseconds). Cell Delay Variation
Tolerance controls the time scale over which the PCR is policed. Note that no remote
CDVT is necessary.
- rcdvt
Keyword that specifies the Cell Delay Variation Tolerance (CDVT) from a remote
endpoint to a local endpoint (1–5000000 microseconds). Cell Delay Variation
Tolerance controls the time scale over which the PCR is policed.
- lcdv
Keyword that specifies the Cell Delay Variation (CDV) from a local endpoint to a
remote endpoint (1–16777215 microseconds). Cell Delay Variation is the peak to
peak cell delay variation expressed in microseconds.
- rcdv
Keyword that specifies the Cell Delay Variation (CDV) from a remote endpoint to a
local endpoint (1–16777215 microseconds). Cell Delay Variation is the peak to peak

- cc
(Optional) Keyword that sets the OAM CC: Enter 1 to enable or 0 to disable. The
default is 0.
- stat
(Optional) Keyword that sets the statistics collection: Enter 1 to enable or 0 to disable.
The default is 0.
The Cisco WAN Manager tool collects statistics for a connection if you enable it here.
Statistics collection is disabled for all connections by default. Statistics collection has
an impact (which may not be significant) on the real-time response, especially for
SVCs (which can be affected even though you do not add SVCs). Therefore, you
should enable statistics collection for only that subset of connections that really
warrants such a feature.
- frame
Keyword that sets frame discard: Enter a 1 to enable or a 0 to disable. The default is 0.

SPVC and SVC Commands
cnfcon
- mc
(Optional) Keyword that specifies the maximum cost (maxcost): a value that creates
a routing priority. If you do not specify this optional parameter, the connection
defaults to having the highest routing priority. Therefore, the maxcost parameter lets
you lower the priority of a connection—but only in regards to finding a route for it.
The range for maxcost is 0–2147483647. The PXM45 does not use a particular route
if the cost for the route exceeds the maxcost.
The cost of a route depends on a cost-per-link specified through the cnfpnni-intf
command. The cost-per-link applies to at the egress a port for all connections of a
particular service type. For example, the cost-per-link is the same for all VBR.1
connections that PNNI controls on a given port, but this cost can differ from all
UBR.1 connections on the same port.
For a route under consideration, the cost is the sum of all the cost-per-links at each
egress in the forward and backward directions along the entire route. In a one-link
route, for example, the cost is the sum of the cost-per-links at two ports.
To illustrate further with a four-link route:
1.
You specify a maxcost of 100000.
2.
The route under consideration by the switching fabric has four links for a total of
eight egress points.
3.
The cost-per-link at six ports is 5040 (the default in cnfpnni-intf), and the cost
per link at two ports is 10000.
The node would use the route because the resulting cost of 50240 is less than the
maxcost of 100000.
Note that you can specify no limit for a service type by entering a cost-per-link of -1
through cnfpnni-intf. A -1 cost-per-link makes maxcost meaningless.

SPVC and SVC Commands
cnfconsegep
cnfconsegep
Configure Connection Segment Endpoint
The cnfconsegep command lets you configure an SVC or SVP as a segment endpoint. When both the
VPI and the VCI are present, the segment endpoint is an F5 flow endpoint (for VCCs). When the optional
VCI is not present, the segment endpoint is an F4 flow endpoint (for VPCs). Use this command only for
established calls.
This command does not apply to SPVCs. The controller gives an error message if you attempt to apply
it to an SPVC. However, you can still use the cnfconsegep command on the SVC portion of an SPVC.
The controller determines if either side (from its perspective) is an SPVC or SPVP and rejects the
command if either endpoint is that of an SPVC or SPVP. In this application, you can use the cnfconsegep
command if a via node exists in the connection path.
Note
Before executing this command, be sure continuity checking is de-activated. If you leave it on,
continuity check failure occurs for the connection. Use cnfconsegep in conjunction with conntrace
for fault isolation.

SPVC and SVC Commands
cnfmbsdft
cnfmbsdft
Configure Maximum Burst Size Default
Configures the default maximum burst size (MBS) for SPVCs on a port. The applicable service types are
real-time and non real-time variable bit rate (rt-VBR and nrt-VBR).
The most likely connection type for which you would use cnfmbsdft is SVC. You can also rely on the
value set with this command as a default for SPVCs if you do not specify an MBS through addcon for
each SPVC of service type VBR.
The new configuration applies to new incoming calls, not existing calls. You can use cnfmbsdft whether
the port is active or in the provisioning state.

dspcon
dspcon
Display Connection
Display information about an SPVC. The contents of the display on the AXSM and the PXM45 differ
slightly. On both cards, the dspcon output appears in sections to make the information easier to sort.
Most of the information in the dspcon output comes from addcon execution. See the addcon description
for more information. Also, executing cnfpnni-intf can affect the dspcon output.
Display Connection on the PXM45
On the PXM45, dspcon shows the following connection identifiers:
•
NSAP address, status, and ownership of local and remote ends of the connection. The display shows
whether a particular endpoint is the master or slave.
The provisioning parameters in the display show:
•
Connection type of VPC or VCC.
•
Service type and compliance (for example, UBR for service type and UBR.1 for ATM Forum
compliance).
•
Bearer class (relates to voice traffic and is reserved for future use).
•
Whether continuity checking or frame discard are enabled (see addcon description).
•
Cause of the last failure. This field can also show that no errors have occurred since the connection
was first added by displaying “SPVC Established.” If a failure occurred, the Attempts field shows
the number of times the system attempted to re-establish service. If no failures have occurred, the
Attempts field contains a 0.
•
L-Util and R-Util are the local and remote percent of utilization assigned to the connection.
Currently, the default of 100% is the only value.
•
Cost values for the connection’s route: the two fields in this category are Max Cost and Routing
Cost. The Max Cost is a cost-per-link configured for a service type (such as UBR) through the
cnfpnni-intf command. When you add the SPVC through addcon, you can specify a maximum
routing cost through the maximum cost (maxcost) parameter. The maxcost represents the maximum
cost for an individual connection. The system uses the cost-per-link for the service type and the
maxcost for the connection to determine whether a route costs too much. After the system creates a
route, the total number of links yields the Routing Cost.
The default cost-per-link is 5040, so if a particular service type uses the default and a route consists
of 4 links, the Routing Cost is 20160. If the dspspvc display shows that Max Cost is –1, no limit
was specified through cnfpnni-intf, and the resulting Routing Cost is 0.
•
Broadcast type: point-to-point or multicast.
The Traffic Parameters section shows the standard parameters PCR, SCR, and CDV in the receive and
transmit directions.

dspcon
Display Connection on the AXSM
On the AXSM, dspcon shows the following connection identifiers:
•
NSAP address, logical port, VPI/VCI, status, and ownership of local and remote ends of the
connection. The display shows whether a particular endpoint is the master or slave.
The provisioning parameters in the display show:
•
Connection type of VPC or VCC.
•
Service type (for example, ABR).
•
A number indicating the controller. For example, 2 refers to PNNI. The addcontroller command
specifies the controller.
•
The administrative state is either up or down. This state results from addcon or dncon/upcon. Note
that, after you down a connection with at the connection master endpoint, the dspcon command
shows the connection as “down” when you execute it at the master endpoint and “failed” when you
execute it at the slave endpoint. (See also dncon description).
•
The operational state is either OK or failed. The operational state can apply to a connection
regardless of the administrative state.
The traffic management parameters consist of:
•
Local and remote UPC parameters of PCR, MBS, CTD, CDVT, and so on. A –1 in a field means that
the parameter was not specified. The characters “N/A” indicate that the parameter does not apply to
the service type.
These other fields also pertain to connection integrity:
•
OAM connectivity check enable or disable.
•
Loopback test enable/disable and loopback type.
•
Round trip delay in microseconds. This field is non-zero only if you previously executed tstdelay.
The dspcon command requires a unique connection identifier. If you do not have the information to
identify a connection, execute dspcons. On the AXSM, dspcons identifies all the connections on the
AXSM. On the PXM45, dspcons identifies all the connections on the node. (See dspcons description).

dspcons
dspcons
Display Connections—display basic information for all connections.
The default usage of dspcons uses no parameters and causes all available information for the
connections to appear. To narrow the scope of the output, use one or more optional parameters.
The dspcons command runs on the CLI of either the AXSM or the PXM45. The set of optional
parameters and the output are different on these cards. (See Syntax Description for the card-specific
parameters.) On the AXSM, the columns at the head of the information fields are:
record
A number for the connection with internal application only. It resides in the
database on the AXSM and is not affected by user input. The system creates
this number when you create the connection. The Cisco WAN Manager
application uses this number.
Identifier
Identifies the connection in the format port vpi vci.
Type
Shows whether the connection is a VCC or a VPC.
SrvcType
The service type—VBR, and so on. (See addcon description).
M/S
Indicates whether the endpoint specified by Identifier is the master or slave.
Upld
The hexadecimal Upload number is an encoded timestamp the Cisco WAN
Manager application uses to determine when a connection was created or
modified. In the CLI context, this field has little meaning.
Adm
The administrative state of the connection. If the connection is down, it
may have resulted from the dncon command.
Alarm
Shows the alarm status of the connection.
When you execute dspcons on the CLI of the PXM45, the output shows:
Local and
Remote Port ID
The display contains a column for the local port ID and a column for the
remote port ID. The port ID has the format that the network controller
utilizes: [shelf.]slot[:subslot].port[:subport]
Local and
Remote VPI.VCI
The VPI and VCI at the local and remote ends of the connection.
State
The State column shows whether the connection is OK, down (by the dncon
command), failed, or has an alarm indication signal (AIS) or abit errors.
Owner
Whether the endpoint is master or slave.
Local and
Remote NSAP
An NSAP address for each end of the connection.
