CLI Procedure for Creating SPVCs

Note: Switched permanent virtual circuit (SPVC) refers to a connection between a Passport 4400 unit and a Passport 6400 unit, or between two Passport 4400 units. SPVCs eliminate the need to configure each node along the connection. The end point is configured, but the connection route is selected automatically.

Use the following steps below to create a SPVC.

1. Display the SPVC parameters:

CLI> show fr port spvcLANData base spvc configured table

A table similar to the following appears:

ConnectId	10
DNA	"[x121]987654321"
MaxTxSize	0
MaxRxSize	0
MinTxThroughput	0
MinRxThroughput	0
MaxTxThroughput	0
MaxRxThroughput	0
TxBurstSize	0
RxBurstSize	0
TxExcessBurstSize	0
RxExcessBurstSize	0
TxPriority	2
DiscardPriority	medium-traffic priority
SetupPriority	2
HoldingPriority	2



2. Add the spvc to the applicable port.

CLI> add fr port spvcLANData

Parameter	Range of Values	Required Actions
<VirtualPortIfIndex>	INTEGER (1..255)	Enter the IfIndex of the local virtual port.
<RemoteNetDLCI>	INTEGER (16.991)	Enter the DLCI number on the remote DCE interface.
<SVCDNA>	Frame Relay DNA (as a quoted string) (1..34)	Enter the remote DNA of the SVC
<ConnectType>	slave | master	Enter which side of the SPVC segment will initiate the call.




Example:

CLI> add fr port spvcLANData 255 16 "1234567890" master

Note: The choice of which device is the master and which device is the slave is by convention. It is recommended that in the Passport 4400-to-Passport 6400 connection, the Passport 4400 be designated the master for the purpose of speedier service recovery.



3. Save the configuration changes and reset the Passport 4400.

CLI> save configuration update

CLI> reset system current reset

The above command adds an entry into the LAN SPVC table. This entry is mapped to the connect ID that is used to identify the SPVCs and the mappings.

To modify existing SPVC parameters, use the following CLI command:

CLI> define fr port spvcLANData (spvc or svc)

To modify the txpriority of an existing SPVC, use the following CLI command:

CLI> define fr port spvcLANData svc txpriority

To modify a local DLCI of an existing SPVC, use the following CLI command:

CLI> define fr port spvcLANData spvc localNetDLCI

Refer toConfiguring LAN Services for a complete description of SPVC parameters.
