Hello all,
Recently i got pretty regular alert from zabbix monitoring my cisco router, the error was interface high error rate.
Did someone have the same proble like me? this is my show interface output

RJ45 and the duplex and speed are hard-coded.
What are the chances that the errors are due to duplex mismatch?

the devices connecting to it's switch and this is from the switch port that connect to that router
sh interfaces configuration g25 Flow Admin Back Mdix Port Type Duplex Speed Neg control State Pressure Mode -------- ------------ ------ ----- -------- ------- ----- -------- ---- gi25 1G-Combo-C Full 1000 Enabled Off Up Disabled Auto
and my g0/0/1 has sub interfaces on it.

- Check software version being used, if applicable use a gold-starred or an advisory release, especially if current version is rather old.

Hello,
what device is connected to interface GigabitEthernet0/0/1 ? It might also help to see the QoS you have applied:
service-policy input WEBUI-MARKING-IN
service-policy output WEBUI-QUEUING-OUT
Also, post the output of:
show buffers
01-05-2021 12:21 AM
the device connected to that interfaces is switch sg350.
i think this qos referring to web-ui
service-policy input WEBUI-MARKING-IN
service-policy output WEBUI-QUEUING-OUT
this is the config

Hello,
I would remove the 'random-detect' from the classes:
class WEBUI-MULTIMEDIA_CONFERENCING-DSCP
bandwidth percent 10
fair-queue
--> no random-detect dscp-based
class WEBUI-MULTIMEDIA_STREAMING-DSCP
bandwidth percent 10
fair-queue
--> no random-detect dscp-based
class WEBUI-TRANSACTIONAL_DATA-DSCP
bandwidth percent 10
fair-queue
--> no random-detect dscp-based
class WEBUI-BULK_DATA-DSCP
bandwidth percent 4
fair-queue
--> no random-detect dscp-based
class WEBUI-SCAVENGER-DSCP
bandwidth percent 1
class class-default
bandwidth percent 25
fair-queue
--> no random-detect dscp-based
Also, try some buffer tuning, starting with the values below (these values double the buffers you currently have), and check if the errors decrease:
buffers middle max-free 4000
buffers middle min-free 200
buffers middle permanent 1800
!
buffers big max-free 3600
buffers big min-free 100
buffers big permanent 1800
!
buffers verybig max-free 600
buffers verybig min-free 100
buffers verybig permanent 200
!
buffers large max-free 600
buffers large min-free 100
buffers large permanent 200
!
buffers verylarge max-free 600
buffers verylarge min-free 100
buffers verylarge permanent 200
!
buffers huge max-free 66
buffers huge min-free 20
buffers huge permanent 40

thank you sir i apply this to my second router and see what happens, because this problem occours in both routers.
if nothing appears in the second router then ill apply to my first router and report back to this forum.
01-05-2021 07:39 AM
hello sir after changing the buffers on both router an alert 'interface high error rate' still appear

This is a switch?
That is a Layer 1 issue.
01-05-2021 03:11 AM
this is router interface connected to the switch
01-05-2021 04:17 AM
Can you check and make sure the switch link does not have speed and duplex hard-coded?
