Configuration

Configuration

If the multicast tree has a large number of leaf connections, for example, 3000, then the cnfportq command should be used to configure the Qbin threshold to be greater than needed for half the number of leaves so as to assure that the multicast group will have no discards. The Qbin default depth is about 1200 cells.

Qbin example using cnfportq command:

•tstconseg and tsdelay commands may be used to troubleshoot a leaf connection both from the BME end point as well as on the other end point

•tstconseg is available on the root connection only on the non-BME end point

•tstconseg is not supported from the BME end of the root connection

•tstdelay is not supported on root connections.
