Chapter 7 SPVC and SVC Commands
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).
