Issue

  • Increasing CRC errors in cluster network ports for multiple ports and nodes. Example of ::> system node run -node_name -command ifstat -a:
-- interface  e3a  (1 hour, 20 minutes, 0 seconds) --
RECEIVE
Total frames:      123m | Frames/second:     456  | Total bytes:      789g
Bytes/second:      111m | Total errors:      222  | Errors/minute:       0
Total discards:      0  | Discards/minute:     0  | Multi/broadcast:   999
Non-primary u/c:     0  | Errored frames:      0  | Unsupported Op:      0
CRC errors:        222  | Runt frames:         0  | Fragment:            0
...
-- interface  e3b  (1 hour, 20 minutes, 0 seconds) --
RECEIVE
Total frames:      234m | Frames/second:     567  | Total bytes:      890g
Bytes/second:      222m | Total errors:      333  | Errors/minute:       0
Total discards:      0  | Discards/minute:     0  | Multi/broadcast:   888
Non-primary u/c:     0  | Errored frames:      0  | Unsupported Op:      0
CRC errors:        333  | Runt frames:         0  | Fragment:            0
...
  • Switch ports transmitting errors and just one receiving them:
switch_name# show interface Ethernet1/1
RX
62347 input error  0 short frame  0 overrun   0 underrun  0 ignored
 
switch_name# show interface Ethernet1/2
TX
44 output error  0 collision  0 deferred  0 late collision
...
switch_name# show interface Ethernet1/10
TX
6 output error  0 collision  0 deferred  0 late collision
  • Switch port 1/1 flapping LED between orange-off-green continuosly
  • The issue remains after cable and QSFP
  • The issue remains after QSFP replacement in switch side
