問題

Output of ifstat in section TRANSMIT indicates increasing Total Errors for interface group, but not for its underlying physical member ports.
 Example: 
RECEIVE Total frames: 72688k | Frames/second: 266 | Total bytes: 207g Bytes/second: 760k | Total errors: 0 | Errors/minute: 0 [...] TRANSMIT Total frames: 397m | Frames/second: 55169 | Total bytes: 512g Bytes/second: 71122k | Total errors: 2720 | Errors/minute: 23
Note: Total errors on TRANSMIT increased
