Every day there is a rapid drop in my connection, this is not all the time, but it happens a few times a day,
It disconnects my connection that I have between my Router01 and my SW1, generating an alarm,
within the company it is only noticed when you are doing tasks where there is a lot of network traffic,
because usually the fall lasts about two 3 seconds and returns to normal.
It shows the message below
*Feb 3 18:12:56.305: %LINK-3-UPDOWN: GigabitEthernet0/0/1 Interface, changed state to down

Hello,
there is a bug, not sure if this is related, and if you have LISP/VASI configured...
%IOSXE_INFRA-3-PUNT_ADDR_RES_ENCAP_ERR: seen repeatedly in LISP coworking with VASI
CSCvv33349
Symptom:
The following messages are seen repeatedly.
*Aug 11 17:43:12 JST: %IOSXE_INFRA-3-PUNT_ADDR_RES_ENCAP_ERR: Punted address resolution packet with unknown encap UNKNOWN
*Aug 11 17:44:40 JST: %IOSXE_INFRA-3-PUNT_ADDR_RES_ENCAP_ERR: Punted address resolution packet with unknown encap UNKNOWN
*Aug 11 17:45:41 JST: %IOSXE_INFRA-3-PUNT_ADDR_RES_ENCAP_ERR: Punted address resolution packet with unknown encap UNKNOWN
Conditions:
lisp coworking with vasi interface
Workaround:
use static map cache instead of send-map-request

I do not have a LISP/VASI configured on my network.
in this case it's a trunk between my router and my sw1 only, then it's filling up with logs because alarms come in all the time

Hello,
also post the full running configs of both your router and your switch...
