EMS event"vifmgr.cluscheck.hwerrors" may be generated for interface group network ports during times of high traffic.

Example:

[Node-01: vifmgr: vifmgr.cluscheck.hwerrors:alert]: Port a0a on node Node-01 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped). [Node-01: vifmgr: vifmgr.cluscheck.hwerrors:alert]: Port a0a-114 on node Node-01 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped)

Or [Node-01: vifmgr: vifmgr.cluscheck.crcerrors:alert]: Port a1m on node Node-01 is reporting a high number of observed hardware errors, possibly CRC errors. [Node-01: vifmgr: vifmgr.cluscheck.crcerrors:alert]: Port a1m-3006 on node Node-01 is reporting a high number of observed hardware errors, possibly CRC errors.

Only IFGRP TRANSMIT Total errors values increase, physical port in IFGRP shows no errors

-- interface a0a (2 days, 19 hours, 15 minutes, 16 seconds) -- RECEIVE [...] TRANSMIT Total frames: 72934k | Frames/second: 267 | Total bytes: 410g Bytes/second: 1503k | Total errors: 48441 | Errors/minute: 11 [...]

Note: Currently 48441 Total errors were counted. Compare with later date/time.

-- interface a0a (3 days, 3 hours, 47 minutes, 23 seconds) -- RECEIVE [...] TRANSMIT Total frames: 72934k | Frames/second: 267 | Total bytes: 410g Bytes/second: 1503k | Total errors: 52183 | Errors/minute: 11 [...]

Note: Total errors is increased. Any ifstats counter has to be compared to an earlier date/time to confirm increase.
