Line Card VC Limitations

The Cisco 10000 series router supports four ATM service categories for virtual circuits (VCs):
•
•
•
•
The segmentation and reassembly (SAR) mechanism configures priority and additional traffic
management parameters for the various ATM service categories.
SAR sets for the service categories.

Parameter
Priority
The number of SAR priority levels and the service categories supported at each priority level vary from
line card to line card. For example, the 8-port E3/DS3 supports the two levels of priority and the service
categories listed in the
The ATM line cards support a maximum number of VCs per priority. That VC limit depends on the VC
limit of the SAR (SAR limit) and the number of priority levels configured.
