SPVC and SVC Commands
cnfmbsdft
cnfmbsdft
Configure Maximum Burst Size Default
Configures the default maximum burst size (MBS) for SPVCs on a port. The applicable service types
are real-time and non real-time variable bit rate (rt-VBR and nrt-VBR).
The most likely connection type for which you would use cnfmbsdft is SVC. You can also rely on the
value set with this command as a default for SPVCs if you do not specify an MBS through addcon for
each SPVC of service type VBR.
The new configuration applies to new incoming calls, not existing calls. You can use cnfmbsdft whether
the port is active or in the provisioning state.
