Routing and Switching & network monitoring

Question

hi i am facing problem in juniper switch Model: ex4200-48t ,Junos: 15.1R6.7 . i deploy network monitoring check-MK software. there is showing errors of juniper switch ports and also show in logs file of switch. One of the error is WARN - [DL380-RU-5] (up) MAC: b0:c6:9a:d7:0a:89, 1 Gbit/s (wrong speed, expected: 100 Mbit/s)WARN, in: 0.00 B/s(0.0%), out: 838.52 B/s(0.0%) . i am facing same error in many ports even also in Snmp port. can you explain me how i can troubleshoot and resolve it . also i am attaching output of switch port with the help of command " show interfaces ge-0/0/6 extensive"

you can check different port errors WARN - [DL380-RU-5] (up) MAC: b0:c6:9a:d7:0a:94, 1 Gbit/s (wrong speed, expected: 100 Mbit/s)WARN, in: 0.00 B/s(0.0%), out: 3.94 kB/s(0.0%) WARN - [DL380-RU-9] (up) MAC: b0:c6:9a:d7:0a:98, 1 Gbit/s (wrong speed, expected: 100 Mbit/s)WARN, in: 0.00 B/s(0.0%), out: 826.83 B/s(0.0%) WARN - [DL380-RU-9] (up) MAC: b0:c6:9a:d7:0a:97, 1 Gbit/s (wrong speed, expected: 100 Mbit/s)WARN, in: 8.74 B/s(0.0%), out: 912.61 B/s(0.0%)

Answer 1

In your output, ge-0/0/6.0 is showing 639 carrier transitions and 4980995 output errors.

Carrier transitions likely means your link is flapping, and output errors suggest that you are saturating the link.

Use clear statistics interface ge-0/0/6 and see if the counters both increment again over time - the link flapping is most likely caused by something physical (cabling etc.).
