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.
2.
3.
4.
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:
•
•
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.
Cisco MGX 8850 Routing Switch Command Reference
7-6
The switch must have a network controller (see addcontroller description).
A physical line must be active. Use the upln command or the CiscoView application.
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.)
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.
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.
