Important: Unless otherwise indicated, all statistics are counters. For statistics with the Int32 data type, the roll-over to zero limit is 4,294,967,295. For statistics with the Int64 data type, the roll-over to zero limit is 18,446,744,073,709,551,615.
All counter statistics are cumulative and reset only by one of the following methods: roll-over (as described above), after a system restart, or after a clear command is performed.
All statistics are considered standards-based unless otherwise noted.
