For an example SPVC, refer to Figure 6-1. An SPVCs master endpoint is on a UNI on Node 1. The slave
endpoint is on a UNI on Node 3. The SPVC traverses a via node, Node 2. If you run the dsppnports
command on Node 1, th e display gives the follow in g information in the fo ur parts of the summ a ry :
Number of connections: SpvcR = 1
Number of configured endpoints: SpvcR = 1
Total of 1 connection, 2 endpoints (1 configured, 1 active intermediate on the via node).
If you run the dsppnports command on via Node 2, the display gives the following information in the
four parts of the summary:
Number of connections: Svcc = 1
Number of configured endpoints: 0
Total of 1 connection, 2 endpoints (2 active intermediate)
Next, a DAX connection has both endpoints on the same switch (the DAX does not appear in
Figure6-1). The summary information for a DAX co nn ec tio n w ou ld ap p ear a s follows:
Number of connections: SpvcD = 1
Number of configured endpoints: SpvcD = 2
Total of 1 connections, 2 endpoints (2 configured)
In summary, each active connection has two endpoints. Configured endpoints translate to the endpoints
added through the addcon command. (shown as spvc on AXSM). Active, intermediate endpoints
translate to the NNI sides for and SPVC or both sides for a pure SVC (shown as an SVC on an AXSM).
