Cyclic timeout on the console port (mgmt / ethernet) - X690-48x-2q-4c

[wrepinski]

X690-48x-2q-4c
ExtremeXOS version 22.6.1.4

Exactly every 15 minutes timeout appears on the mgmt (ethernet) port.
No ping response, hangs up the connection.
The switch to which the mgmt port is connected does not report breaks or problems with packets or transmission.

Please tell me what else I can check.

To the same switch, the port next is connected to another switch with the mgmt x690 port. There is no problem there. The switch configuration for both ports is identical. I checked, MAC X690 is not lost from the arp / fdb table.

That quite sounds like the upstream switch aging out the MAC address of the EXOS switch’s mgmt interface. To confirm, check the MAC address table timeout of the upstream switch.
