Add Connection—AXSM, AXSM-E, AXSM-32-T1E1-E, AXSM-XG
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 or SVPs.
AXSM supports a maximum of 64K SPVCs. AXSME supports a maximum of 60K SPVCs–4K are
reserved.
The connection is either a dual-ended connection or a single-ended connection. For a dual ended
connection, you first add the endpoint at the slave-end switch. Upon successful addition of the slave
endpoint, the slave-end node generates a 20 octet NSAP address for that endpoint that is used at the
master endpoint. The slave endpoint identifier uniquely identifies the endpoint in the network, and you
must use this identifier when adding the master endpoint of a dual-ended connection. For a single-ended
connection, you add the connection only at the master end.
Note VS/VD cannot be enabled on the port with WFQ disable in SCT.
Warning
Changing connection parameters will result in a momentary loss of traffic.
Warning
Changing routing parameters will not take effect on the slave endpoint of a DAX connection.
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 the addcontroller command in the Cisco MGX
8800/8900 Series Command Reference, Release 5.2).
2. A physical line must be active. Use the upln command.
3. At least one logical port must exist on the active physical line. Use the addport command to create
the port. If necessary, modify the port through cnfport.)
4. At least one resource partition must exist on the logical port. Use addrscprtn or addpart. The
resource partition should be associated with the controller added in step 1.
5. Optionally, configure the version of the UNI by using the cnfpnportsig command at the PXM card.
UNI endpoints do not require signalling. However, although the default interface type is UNI, no
default exists for the version of UNI. Remember to up the PNNI port by using the uppnport
command at the PXM card.
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
characteristics pertain to this master-slave arrangement:
