   I'm having trouble figuring out the difference between abr and ubr+.
   
   The docs show this for ABR
   In ABR transmission, the peak cell rate (PCR) specifies the maximum
   value of the allowed cell rate (ACR), and minimum cell rate (MCR)
   specifies the minimum
   value for the ACR. ACR varies between the MCR and the PCR and is
   dynamically controlled using congestion control mechanisms.
   
   and this for ubr+
   To select Unspecified Bit Rate (UBR) QOS and configure the output peak
   cell rate and output minimum guaranteed cell rate for an ATM PVC, SVC,
   or VC class,
   use the ubr+ command in the appropriate command mode.
