SPVC and SVC Commands
cnfabrtparmdft
cnfabrtparmdft
Configure ABR Traffic Parameter Defaults
Configures the default ABR traffic parameter(s), used for SPVC, per port.
Note
Currently, this command is available but has no effect.
When a user requests an ABR connection, the controller adds the default ABR traffic parameters before
the connection is committed. The user can change the ABR traffic parameters, per connection, using the
cnfabr command available on the AXSM.
The default ABR traffic parameters are used in the SETUP message at the source when an SPVC for
ABR service category is set up.
