The router maintains counters for queues within the system for granular billing and accounting.
Each queue maintains the following counters:
counters for packets and octets accepted into the queue
counters for packets and octets rejected at the queue
counters for packets and octets transmitted in-profile
counters for packets and octets transmitted out-of-profile
The counters available vary among the 7210 SAS platform. Not all the counters are supported on all the platforms. Additionally there are restrictions on the number of counters that can be used simultaneously with a single queue. Some platforms can only count octets or packets and other can count both packets and octets. Counter (and corresponding accounting record) support available on each of the platform is listed in the 7210 SAS-D, Dxp, K 2F1C2T, K 2F6C4T, K 3SFP+ 8C System Management Guide in the Accounting Records/Logs section.
