This read-only value holds the committed access rate, described as the sustained rate permitted by the rate limit. This is the actual bits-per-second threshold CAR uses to distinguish conforming from exceeding traffic on this entry, so it's the number to compare directly against ccarStatSwitchedBytes and ccarStatFilteredBytes growth over time to judge whether the configured rate is well matched to real traffic demand or is being hit constantly. A rate configured at 1,000,000 bits per second with ccarStatFilteredBytes climbing steadily during business hours would indicate the traffic this entry governs is regularly trying to exceed its 1 Mbps allowance.
